i have a 2001 pontiac sunfire 2200 4 speed auto . i thinkin bout getting a obx header off ebay for it but i want to know some of yall opinions bout it first . any problems with it ? and can you tell the difference with it ? i have 2 1/2 inch piping from the flex pipe back and no cat just a ractive muffler . thanks for any info yall give me .
Man, I would think about changing your exhaust setup first. Having no cat is hurting you, plus the 2 1/2 inch piping is too big for our cars unless you're running low boost or whatnot. Adding a header wont do you any good unless you fix your exhaust setup first. Hopefully that helps
I need a sig
you might get 3-4hp off it
