I'm going to be ordering a downpipe probably later today, if not, tomorrow...

I was told to do both, get a cat and get rid of it..

I have stock everything when it comes to exhaust.. except a flowmaster muffler..
That thing already sounds like total ass once I hit about 3k..

I know the catless will be louder (still not sure how much?) and i'm already loud w/ that muffler..

What're some of the advantages and disadvantages of each..

Thanks.

get a high-flow cat

advantage to catless is slight hp gain. disadvantage is exhaust sounds raspy(some people like it, most dont) and that youd need to get someone with hptuners to delete the cat from your system. also wont pass inspection catless.


advantage to cat is way less rasp sound and not having to use hptuners to get rid of it in your system. disadvantage is slightly less hp gains. cat will pass inspection even if its a high flow cat.

im catless and have ZERO rasp! the secret is to get a 20+inch glass pack to put after the downpipe.. then u have 0 rasp!

do you have any video clips of your exhaust. ive been wanting to see what glass packs sound like with a catless 3" dp.

I was catless for a while to, and had zero rasp. My secret was my Corsa Catback. I just got sick of the smell. The exhaust smelled like my pop's 65' GTO.

I also passed inspection, but PA does not use tailpipe sniffers so can't say this would be true everywhere.

I'm Currently running the ZZP 3" catless DP w/ stock catback. raspless until recently, think my resonator and/or muffler has come apart. My reasoning was the slight hp gain, and I don't want to keep going through cats. I had already went through 2 on my stock setup..

i already have the catless dp. now im just waitin for Brad at Bad Mab to ship me the header. im at a stage of not knowing what im going to do as far as the exhaust goes. i hope it sounds good with glass packs cuz i can get a really good deal on 1.

The only reason I would want to go catless is to be able to make flames out the back )))

Don't glasspacks blow out after awhile? How long have you been running the same one?
