And how do I measure my header to tell if I've got what's considered a short or long one?
I understand the theory of pipes but is the one thing I've never gotten into and fully understood. Need some help. I know it won't be the BEST choice but if I can measure my header and you can tell the the pros and cons of the 9886 with an S5 I sure would appreciate it!
I have never ran that pipe before. I just want to say I just got my first GO 7port and dammnnn its fast. It's a good bargain at $209 I just can't testify to long life which is my favorite thing about the RB's. Well maybe it's there ease of tunning or maybe it's the way they scream as well. Definately impressed with the GO!!!
