Have you done any dyno time with these cans, or feedback from customers with regard to power/torque improvements after remapping?

Nice looking slip-on's :)

there are plenty of people who have used these types of mufflers from me and others and the mufflers themsleves were not make or break on the dyno. most makers don't dnyo mufflers but they are very loud LOL

the pipes are going to be run of the mill as far as performance and i am not personally goiong to make claims. there are people who have bought them and with a remap they were happy. Please keep in mind i can sell you mufflers to retrofit you Erion pipes or supply you will a few pipe options too

let me know if this helps?

Thanks for the quick reply. The cans certainly seem light, Im guessing lighter than my Erions though I haven't weighed them.

There are too many options for the mufflers to make dyno'ing worthwhile. there are 3 sizes of core size, several sizes or rounds, many lengths and inlets i could dyno the same muffler in 20 different configs and get 1 hp either way. I have yet to see any other maker dyno their mufflers alone for claims so i ahve felt no need to do so for mine. I can't dyno and make custom maps for cans.

I do however plan on doing the slip-ons complete vs OEM and any new full exhausts as time and systems permit.

If you have any questions please feel free to contact me i am eagerly awaiting

Most manufactures provide dyno figures for the exhaust the sell...after all it is supposed to improve performance right? :confused:

not factual John.

most don't, very few do.

just FWIW look ate the greatest slip-on ever for the 51-sato. find me a sato dyno made by sato not a third party.

the reality is the is no way to dyno muffler but again we have been through this already:rolleyes: the variables on muffler length, core size, and shape would be impossible to dyno. I am doing dyno work on fulls but for the 51 the simple slip-on is a simple slip-on IMO. I make no HP claims so i don't feel i have to prove they do anything other then sound great and look great too. As i move forward i will do the best i can to work harder to be providing more dyno info but when people buying MGP growlers for $289 and complaining about them costing too much there is not much incentive for high end exhausts, again look where sato is now with them, defunked.

You can call me john i would love the chance to speak with you more in depth about any questions or concerns you might have. I am all for bikes and i look forward to making more parts and offering more exhausts and i welcome your thoughts

Sato always did on their Japanese site, but the main US importer made many Dyno runs, both on low and high mount.

Why dont you focus on 1 or 2 then and have them make power, why do I want your exhaust if it will not increase performance?

Last I heard Sato's were in high demand for the 51. Did'nt you make a copy of them? What do you mean defunked?

their importer soley made the brand from a warehouse company to huge here stateside. i have not seen any sato graphs but that is not the point. my point is show me all the graphs from all the slip-on companies that are not the importers or sellers. i can find you 10 makers for the 51 with no graphs and people buy them why shoud i do what million dollars companies don't?


Why dont you focus on 1 or 2 then and have them make power, why do I want your exhaust if it will not increase performance?

same reason people bought sato or others GP cans without any perfomance gains, they were cool looking, cool sounding and mine are custom made and not many offer that. I do intend on working my way up and offering stuff like ti pipes but the economy and people will not buy it right now and that is part of the reason companies like arata and sato don't even make pipes despite all their glory and high end appeal they can't sell them. the market wants unique and cheap and making $1400 slip-ons for a 10 year old bike is not happening even if it made 10 hp and was all ti nobody is buying em.

People want sub $300 MGP growler type slip-on that are loud and cheap. i am trying to sell what they want and continue to grow until cooler projects allow. i am trying for this 2-1 ducati full coming soon and a high and low mount full RSV4 too but again, not much there for customers and it is not just me, ask around the exhaust market is crap all over.


Last I heard Sato's were in high demand for the 51. Did'nt you make a copy of them? What do you mean defunked?

i did not copy them unless you call high mount location and using pipe a copy:D I had made a similar mount because of the fact people like that, supply and demand. I used different tapers and added a bolt on carbon boot guard to combat the years of people complaining about burt boots so i feel i did a upgrade. Mine together are actually lighter then a set of sato's because my larger cars are lighter then sato's even with steel piping vs ti, again not too bad IMO. OH, i use ceramic coating as standard, who else does that?

i am working hard to get some small options moving to get in the postition to attempt a larger scale high end deal but you can't just make a thing like that overnight. In a year and a half i went from mrgrn's mufflers to retofit to BD and now fulls and slip-ons.

give me some time and support and i will keep trying to grow and expand:)

would be nice if you did, i am not so nice on the net:D

be great to speak with you and my door is always open if you hit louden

Why do I have to produce the graphs, I don't want to sell the exhausts, you do. Jardine has them, as does Akro, you gotta dig but they are out there, all of those exhaust companies have dynos in house.

Yeah I noticed that after poking around a bit on SpeedZilla, any reason why?

I read this thread over there:
http://www.speedzilla.com/forums/rc51-general-discussion/60806-chronicles-mrgrn.html

and I gotta say I am a little leery of doing biz. What is the deal with that guy rothman and you and jami69.
That thread is pretty long but there is a lot of crazy stuff in there about you.

you have posted the same link twice that i have not read, why?

I read this thread over there:
http://www.speedzilla.com/forums/rc51-general-discussion/60806-chronicles-mrgrn.html

I have had jamie on ignore there for 2 years, i can't even see what he types and glen is pissed because i told the truth and he took it personally. the whole point of the thread to damage me and i am not even bothering to deal with it as it makes no sense. i am here if anybody has a real issue but people causing hate fed threads are not what i am into.

I am not even going to resond more to a thread made in the sole purpose of ruining me and my bizz with the same people joining forums to bash me and link the same thread over and over. Neither Glenn or jamie bought anything from me and a few of them stand to gain in their bizz if i lose mine;) and the rest is banter from a forum with no mods, a free for all forum if you will and what's good for the goose is good for the gander i spose. I have been there for 10 years and long b4 i made or sold anything i must have made fun of somebodies racer in jest now 5 years later some of them join sites to start crap, Oh well

i have ecellent feedback on forums and ebay from actaul customers and i back my products 100%. I am here to call, email and PM if you have questions or issues.

I am hoping i get a change to serve and if you feel like it give me a call and let me have to chance to show you i can provide a great product and CS instead of selling me short due to a few trouble makers with a agenda

yes, you ahve names the largest afermarket exhaust company in the world and one would hope akra had their own dyno. you have named a couple of the largest but you sad most i believe and i said that was not factual, most don't. Factually about 1 out of every 25+ do if that and i am a small deal working on custom mufflers not akrapovic

I just read that brake caliper thread and I don't see where he edited anything which I guess was the issue, you never seemed to answer that.
. i am here if anybody has a real issue but people causing hate fed threads are not what i am into.
Understandable, but you seemed to have a lot of that hate in all those links, lots on other forums to.

There are lots of people there saying a lot of things and linking to a lot of forums, I think you should anwser that, if nothing else to refute it, because if you say nothing and remain silent then maybe it is all true.

Well thats fine but there is all kinds of stuff all over the internet saying the opposite, and as a potential customer that worries me, I would like to see you refute that stuff on SpeedZilla, I like that site as it has a lot of good info this forum is missing.

Mrgrn, that is more than just a couple trouble makers, I think you have a serious image issue you have to get squared away before you can sell stuff.

I am not sure I understand, can you clarify?

here is one.

i don't feel i have to argue on a site with no moderation. the same people are on the same forums slandering the same things repeatedly. i have been a round for over a decade. i am not saying i have not rubbed somebody the wrong way but that is the net. Stuff that is said about my bizz is intended to slander and lose me bizz and if you can't see that i don't know what to say really. A real customer will call, email, or PM me and i will resolved it. How is it people without a sale from me are considered viable or believeable. i can't refute lies and crap. Until i have a email here or a call from a customer from whom i have really done something wrong too the rest is a attempt to hurt and why repsond and rerute to further make the circus go around or is that the point? I think you will see it is the same people with the same tube posting hundreds of times like it is fun. it is some form of entertainment for them i think. if they truly had a issue i have been here waiting as a man to deal with it or resolve it and it never comes;) you don't find it odd people who i have never done bizz with join sites to start threads that try to damage me and my efforts? a little scary really IMO. say your beef and move on.

Like i have said. i have had some fun on the net as much as the next guy and at times i have been heated and or taken too serious. i am also a fun target because i make things and sell things while others have nothing on the line to win or lose. I have tried to contact a few persons to rectify the sitations they might have with me for spite or whatnot and i never hear back. hard to worry too much about people i have not done bizz with who are out to damage me what came come of some trash fest?

i am here and really there is no need to hash out why people are messed up and if you feel i have done you wrong email, PM, or call me i am always here no worries. I will be glad to show you what my customers know or you can listen to what trouble makers say trying to lose me bizz. I get pissed at times but would never try to damage a person trying to better themselves and help because i was angry over petty stuff.

Any time I want to buy something online from a new company I always Google them first, and curoius about your company I had a look today and on the first page is this:

http://www.r1-forum.com/forums/showthread.php?t=295540

A thread on the R1 forum from last week that says do not buy from mrgrn.

So I am just saying maybe work on the business image a bit before making any more products!
yo know exactly who i am and you kow i am not new.

pretty hard to keep working on it when every post is the same thread posted.

i have handled the situation correctly and i feel i did nothing wrong. i am sorry for the customer and refunded the money, can't win them all

Well mrgrn, I believe in the saying where there is smoke, there is fire.

I just read some more of that thread, sounds like that guy that started it was pretty clear he was not trying to hurt your business or bash your parts, his problem was how you treated people.

I think you should go square things away with that dude, he seemed pretty sincere. ( and there is like a dozen pages of people agreeing with him )

Good luck! :(
