@CYBER-NINJA alot of that guide is correct, but things like cutting and chopping up the inlet manifold is just bollocks, you loose power doing that, dont take this guide as gospel

@tunertom I take your point, my DTR had it's stock front pipe cut open and derestricted. I was unable to test for a before and after to feel the difference personally. But it's probably a safe bet that most owners will not go to that trouble and just swap the whole exhaust over for a DEP, Giannelli etc or similar after market exhaust set-up.

@tunertom Yeah that inlet manifold is a load of tosh, but don't discount Scrim, he knows his shit.

@CYBER-NINJA haha yeah I did chop my exhaust up and removed the cat, but oh my seriously those pipes have some serious weight, so if not for the performance the weight alone is worth swapping out lmao!

@Calum Added bonus with the weight saving as well - good shout dude!!!

@CYBER-NINJA Weight is a restriction that affects every single aspect of performance.
