dohner did you ever delete that stuff? how's it sound and do you have the stock mufflers, you should try and get some sound clips

I've heard plenty of 3800's with no cat and frankly I think it sounds like ass. The cat isn't hardly any impedance to flow (unless clogged) so why bother? Get an aftermarket or something.

im going to swap out my dynomax turbos for stock mufflers. so it will be plog, pem, 2.5inch racepipe, dynomax res and stock muffs, i might go with a spiral flow, im having a custom 2.5 inch system made

the mufflers arent anything special, I got them off ebay, look cool so i thought I'd just give them a chance. here's the address

Just thought I'd let you guys know, the mufflers that I told you about that I bought from ebay, are amazing, they look great in person and sound incredible, very deep rumble, now i just have to get rid of the cat and ubend. very very pleased with the mufflers.
