Hi I have the Staintunes on my TBA and they sound great about in line with the Thunderpipes, the workmanship on these pipes is first class and they will last the life of your bike. thay have baffles you can remove so pop them out for loud, pop them in to tone it down. takes 3 mins to put in or out.
Have a look on the Staintune web site, these pipes make a Triumph sound like a Triumph should.
Safe Riding out there
