Cats or no cats what is better?

Cantbeatblack · October 2nd, 2007, 09:54 PM

i have a X pipe with cats on and i had bought the car with them on here i was thinking about buying a x pip w/o cats but i was wondering if there is any differnt with or without cars on a X pipe

with the way that high flow cats are engineered these days, there isn't really going to be a difference either way. i have cats due to my stay requiring them and i have a little bit of hippie in me

Simple decision. Cats are for emmisions. If you have annual emmisions check cats are your best friend.

will is sound any differnt without them?

GTsetGO · October 2nd, 2007, 10:00 PM

yeah they have a different sound, but I can't remember what it does to it though

The only difference I noticed was at idle. It was slightly quieter. But at full throttle it sounds the same.

I installed a non-Cat X-pipe with my stock GT mufflers and the car is considerably louder. Almost too loud. The sound is completely different than previously. The change in sound is due to the X-pipe, but again quite loud. Hope this helps.

i have a catless h-pipe with magnapacks. it is a loud friggin exhaust. your car will be loud, and illegal if you do no cats, but it sounds so much better imo. if you want that bad ass deep fuckin roar, you will love a catless pipe.

silvergtstang99 · October 3rd, 2007, 02:38 AM

o/r x-pipes are a little raspier than catted ones and they are louder!!

when i had my headers and o/r x-pipe installed at first i didnt have my flowmasters on yet so i had the stock ones. it was a little louder but mufflers/catback make THE biggest difference!! my faves are flowmaster and the borla stingers!

gotta love the sound of a v8 stang!

superbeef1000 · October 3rd, 2007, 02:55 AM

stay with the cats ,,its a minimal gain to not have them

GTblackprodigy · October 3rd, 2007, 03:01 AM

without cats you get a raspier sound..also i think i've heard cars dyno more with cats taken of but the gains arent incredible or anything..so i dont know

energiesource · October 3rd, 2007, 03:02 AM

id get o/r for the sound not the gain
