Do you run 3" cats or 2 1/2"?

I read the sticky and I get all the velocity stuff. The pacesetters are 3" collectors. Do I want 3" cats maybe reduced to a 2 1/2" X-pipe and 2 1/2" in/out dual mufflers? Or put a reducer on the collector and run 2 1/2" cats?

About to blow $800 on exhaust parts and I just want to get the right crap.

I'm looking at LT's, cats, X-pipe, dual Dynomax super turbos, rear exit.

Have a 440 hp Ls6 with a mild cam and CAI, Hp tune, using all o2 sensors, no egr, no air pump, street use, 3.73s

I do. AS&M headers into 3" Magnaflow cats reduced AFTER the X into 2+1/2" pipe and dual Borla XR-1 Ovals.

I run pacesetters reduced into 2.5" stainless through high flow cats and hooker aerochambers on the back end. xpipe will be added soon and cutouts will replace cats soon as well.

I got 2.5" off each header, no kitties, then IMCO x-pipe, with two borla oval mufflers dumped right before the axle.

Don't mean to thread jack but who makes a catted y-pipe that will mate up to pacesetter LT's without modding or welding or anything like that?

I have pacesetters long tube headers with 2.5" pipes for Magnaflow high flow cats into Flowmaster Super 44's all 2.5" then after the mufflers I go to 3" out then 4" tail pipes out the back, no X pipe either.

Bill, do you have any pics of your exhaust (I know you posted them ages ago but I believe that they're gone)? It's the coolest set up that I've seen on a 4x4, with equal length pipes
