does anyone have the xtc downpipe on their car w/o a cat?

i am trying to decide wether or not to go catless with that downpipe or get the one with the high flow cat

That is honestly entirely up to you. Do you have somewhere you can get an inspection? What are the consequences if you get caught with out a cat in your state?

 

in pa...u can do catless and passed emissions as longs as the engine light dont come on..but i didnt kn ow dat otherwise i would had went catless..

is it louder w/o a cat.?..mine car is loud with the cat

 

no i am not worried about the penalties basically what i want to know is it will pry throw a check engine light how easy is it to clear and once it's cleared will it keep re-appearing and whoever has the xtc whether or not they like it

 

go with the high flow cat, that way you dont get any cels, you wont notice a huge difference anyways performace wise, but you sure will sound wise the catless is quite a bit louder. They did a test a while back in one of the sport compact magizines about exhausts with a high flow cat coverter and one without, there was very little difference performance wise like maybe 1-2 hp difference, why put up with the hassle of CEL's and a super loud DP for 1-2 extra HP over a catted DP, just my thoughts others may disagree it just comes down to whats important to you?

 

i have a high flow cat on my d/p and i got 3 codes popped up i had to get them deleted at the local shop where i had it put on

 

catless if you want to be cool

 

Is the CEL's becuase you are running a 3" DP on the 2.4? Is it to big for your application or is it a Bad cat on your DP? or others? just curious?

 

I do not see any reason to go catless and polute more than you need to.

also, in pennsylvania, it is illegal to remove any factory emissions control.

 

quicksliver how do you like you zzp downpipe with the magnaflow cat??

 

I liked the downpipe, but my flexpipe actually broke on it so I just removed it, if I were to do it again i probably would have went with the 2.5"dp with cat for that extra bit of torque, the 3" is better in the high rpms but i drive most of the time in the mid rpm range and I think a 2.5" would have been best, however the 3" is a great peice i just have a faultly flexpipe, i am just going to order a new flexpipe and have my exhaust shop weld it back togather, you will notice a drop in boost but no loss in power just more efficient. I lost .5ln of boost from 17.5psi to 16.5psi
