OH MY GOD NO!!! According to 70% of Stangnet here Flowmaster makes you LOSE power...you would probably have like 500rwhp if you put on Magnaflow!!! One guy claims Flowmaster alone made him lose 8rwhp
You know if you just end all of this and supercharge your Bullitt you will be a lot happier. Forget the stroker kit, if you wanted to touch the internal engine you just of just gotten an older muscle car thats what they are there for. Or like Kenny know what you are doing with a mod engine 2v.
