im thinking of geting a DP but i dont know which way to go turbo xs,cpe, orthe Corksport what do u guy think
I voted for the Corksport as it allows you to keep the main under car cat.
I thought the "main" cat was the one on the dp.
Nope. The car has 2 cats - the pre-cat is built into the stock DP. The DP attaches to the main cat and the exhaust goes from there.
CP-E and most others DP's remove BOTH cats and replace with one hi-flow cat. The Corksport is technically a shorty DP and has no cat built into it ... just bolts right up to the main cat. Good if you need to go completely catless 'cause you can then replace the main cat with a test pipe or if you need to worry about emissions testing 'cause I'm sure the main stock cat is better than the hi-flow ones for cleaning the exhaust.
I disagree. Whatever you want to call it, the 1st cat in the downpipe is the one that will throw a CEL when you get rid of it. The rear cat has no effect on the engine or ECU, its there simply for the EPA and emissions standards.

cp-e trust me this coming from expierience
My previous Turbo XS DP through a CEL light and there was no remedy but to reset it every dayI simply don`t like any CEL`s period wether the car is modified or not because not having a CEL, the mod was truly engineered and designed correcly,therefore any mod causing a CEL should not be put on a car in my books.

Hey Aaron. What are you actually disagreeing with on my post?
I'm with you on the elimination of the 1st cat being the one that causes the CEL. And I agree with your comment on the function of the rear cat for emissions. Up here in Ontario they put the car on a dynamometer and put a sniffer up the tail-pipe and measure a whole bunch of pollutants with a read-out provided to see if you're in spec or not.
I think we're both correct in what we're saying, but for the sake of clarity, I'd like to know what the dis-agreement is on.![]()
