^_^ Hi to all the pro, i got some exhaust questions. I hv search for lots of thread, but still can't really get the conclusion. Any1 can help? Pls only tell the fact, and dun jz guess guess only, it will make me blur~~ ^_^
1)Extractor - What is the different for OEM short route 4-1 direct to turbo compare with aftermarket long route extractor? (Izit OEM short route gv more touqe, aftermarket long route gv more HP?)
2)Downpipe - Lets say the turbo turbine housing come with 2.5 inches, izit best v follow the housing size 2.5inches, or make it bigger lets say 3inches?
3)Midbox/Bullet - Lets say if the piping is 2.5inches, izit best use 2.5inches bullet or bigger like 3inches? will bigger size bullet cause turbulance inside the bullet itself create unwanted backpressure?
4)Muffler - Again, follow the piping size or bigger? ^_^
