An exhaust gasket leak should not cause your bike to stall.
Does your exhaust smell very rich in fuel? If so, you may have a bad fuel pressure regulator, which is not an uncommon item amongst Hondas.
The '01 exhausts are different than the '02 due to the different swingarm designs.
Plus the SP2 used D-shaped exhaust ports while the SP1 used round ports, although both used round exhaust gaskets for the head pipes.
The SP1's were only made two years ('00-'01), so most of the accessories were for the SP2 ('02-'06).
And most companies ceased making exhausts for these bikes years ago.
There were some exceptions, like LadyBird Performance, but even their full systems were only for the SP2.
About the best bet is to install a slip-on system from LadyBird Performance.
These are about on par with Sato, which was the best slip-on system, but also out of production.
Search for user SimonKobeJapan (at LadyBird Performance) and send him a PM. He is a super nice and helpful guy. And LBP is a real high quality product.
Their HRC replica full system has welds that are works of art.
Almost a shame to mount that exhaust and expose to Nature.
