Thinking of changing from magnaflow 3.5 to a 4 inch or dual 3 inch. Input please!
Hey guys
I have been toiling with this for a while now. I have a single 3.5 magnaflow exhaust on my truck now, and I would like to know what you guys think as far as exhaust restriction. I have a 4.125 stroked L92 engine with a TEA heads and ported L92 intake, with 90mm intake. the exhaust currently is 1 7/8 Kooks headers to a 3 inch y then to the Magnaflow cat back with resonator. I am preparing now for a Fast intake and custom 4 inch intake setup, and I am just wandering if i would see any gains with eith of the two upgraded exhaust in comparison to the current 3.5 magnaflow.
Also anyone running a dual 3 inch or single 4 inch exahaust;that changed from a single 3.5. Were there any gains, and how your setup respond to the change.
Thanks
