I plan on (gotta love the military bonuses) ordering a DP on Monday of next week and can't really make up my mind which one. Anyone have the catless on their stock exhaust and it sounds ok? Anyone have any recommendations?

 

ive got a catless zzp dp and the zzp header and it sounded ok on stock exhaust...

the power blew out my stock muffler so now i have a corsa exhaust and it sounds sexy

 

I have an adm full turboback and I love it. Catless os course

 

I've got a TC running a catless downpipe on the stock exhaust. It sounds the same when sitting at idle. Under light throttle its only a little louder. When you step on it though, it sounds badass.

 

I've had the Cobalt-Addiction/XTC 2.5" cat-less downpipe on my car for almost 3 years now and I love it. At only $180, it was money well spent.

 

We sell A LOT of the Hahn catless DP's... Many more than the "catted" ones...

 

i have the catless hahn thru the stocker catback

sounds great

 

Thanks everyone, sounds like catless is what I'm gonna do. Just gotta narrow it down to which brand!

 

go with CIA... good product, low price, no codes!

 

i have a catless dp on my stock exhaust, sounds ok once its warm but when you get on it it sounds raspy.

 

It's gonna sound much different on an SS/TC compared to your SS/SC.

Go with Dejon Performances catless DP with cutout. Only $299!!

 

Hahn Catless on stock exhaust here...

Sounds identically to stock in idle. During normal driving it sounds completely stock, WOT it definitely sounds louder

 

so can u run catless with no check engine light

 

if u get the hahn or CIA... some of the downpipes are known to throw codes

 

With the hahn and CIA yeah because of the angle they put the bung in

 

what happens when you have to get your cars emissions done? since there is no code its ok?

 

Yup that is what most will say

 

I thought the angle was to prevent condensation/moisture build up to the sensor its self? But no ones throwing codes being catless with these?

 

so no codes and people are passing emissions?

 

No codes....but passing emissions I have no idea.....Dont have to worry about that stuff anymore atm

 

Hahn catless DP on mine too. Not loud at all.....unless you get on it. No CEL after 1300 miles of driving! Will not pass visual inspection, but if they just hook it up to the computer to see if you are throwing any codes, it'll pass. Depends on who's inspecting.

 

I threw a code with mine but i erased it with hp tuners so its gone for good lol

 

Hahn DP and no codes. Was catted now catless. Emission testing you will definately fail. Anyone with a nose can smell the fact that your cat is not there or working. Smells like a 4 stroke dirtbike now.

 

ya i have the xtc catless down pipe only thing is im throwing a cat code i need to get that fixed though sorry to get off topic but did any one do something to there o2 censor to not through a code like an extender or anything?

 

Get it tuned out with Hp tuners.
