quick question about dp on my application
ok...so im going tomorrow to have a new downpipe and exhaust installed at clear image...im using my exhisting muffler and clear image tri y header....but the question. In the long run, will i show a worth while gain by going catless??? i know some people say its raspy...but what exactly do you mean by that. For my application as of now I have a CAI, 4--2-1 header and a tune plus it will have a 2.5" exhaust with a resonator and my muffler is a canister style magnaflow. Eventually im going to do a full engine build with a higher compression and staged comp cams.
Just wondering on ya'lls opinions...and i have to go in tomorrow morning...early...so ill post up what i decide

ill have it tuned out. when i got there they hadnt gotten thier shipment of cats in...so i am now catless
he had already bent the pipe for 3"...so we did a 2.5" dp with a magnaflow resonator, 3" exhaust piping with my existing 2.5" muffler...so i do get backpressure, but the exhaust is also ready for future upgrades if needed.

also as far as emmisions, make sure they don't do a visual test. i had a buddy that welded a heat shield on so if you take a look under the car, it LOOKS like there's a cat there

sigh... again... you don't want backpressure what do you have planned in the way of mods? 3" is way too big unless you're going turbo. unless you're doing a HUGE n/a build it will be too big.

i am going to be doing a FULL n/a build...higher compression, all internals, port and polish heads, everything i can do.
