after all the talk i guess flomasters the best but the system they make for 3.8s is 2.5, most of u guys have custom 2.75 or even 3in. Isn't there a reason they only make 2.5in for our cars? We need a certain amount of backpressure. What size catback will give me the most hp gain? And if 3" is the case, will the 3"american thunder for the v8 fit my 3.8??
**P.S. the only performance mods on my car right now is the slp cold air scoop, and whisper lid and all i wanna do is make my car faster, if that helps)
