Cat Back diameter question

[paco]

I have a Matrix universal muffler. I like the sound.

<div class='quotetop'>QUOTE(dicksteel)</div><div class='quotemain'>well fellas, with all of this talk about I-4's and 2.25" exhaust, how about a V6? would 2.5" still be to big or would it work alright because it is a bigger engine? thanks</div>

umm i must be the freak of the group but i have mandrel bent 2.75" piping on my N/A V6. i have a THERMAL R&D straight through muffler, MPH downpipe w/ hi-flow cat (no pre cats) and an AEM CAI w/ bypass. we figure i am pushing about 225hp to the flywheel; my car is faster than stock as i run 3G GT's often and almost always walk away (unless of course if they're modded similarly). if u r not going forced induction or squeeze, i suggest doing 2.5" on the V6 to avoid scavenging. once i get my turbos, i will move to 3" piping and a new muffler.
