Thanks mototireguy, I'll give him a call.
I'm just looking to remedy a recurring problem with the crap Triumph put in after the collector (frozen exhaust butterfly valve and dead servo motor). So replacing a chunk of the stock exhaust with a stretch of straight pipe will do the trick. 2 cuts, 2 welds.
I would have to buy a 'full system' and I've only found 3 aftermarket options starting at $1000 and way up from there.
