So i recently purchased 2 manual cut outs the one with cables you have to pull "mr.gasket`s" What i plan on doin sense i have already butchered my stock H pipe. I had an exhaust shop home make an Offroad H pipe. so i will install cut outs by tranny.
My other friend has a 335i whom took off his secondary cats. which are alot less restrictive then stock gt cats.
I plan on installing the cats after my cut outs with my current stock mufflers. So its sounds super quiet.
then all of the sudden a monster gets unleashed. I am hoping i can shoot flames

 

Couldn't shoot flames when I ran just my o/r h and no axlebacks.
