i dont know if i am posting it in the right place or not but i am wondering why does a check engine light turns on cuz mine is really bugging the shit out of me and i want to the delarship and they told me it was cuz of my exhaust and i am wondering if it could be that?

thanks and hopefully im not asking a stupid question

Its a valid question, but we need more info. What exactly have you modified on your car?

nah man when i got the car from the delarship it came modified already. and from what i know it has a invidia exhaust, turbo timer, boost gauge, lowering springs, SAFC witch is protected, after market clutch, and from what i can see in the engine only a home made boost controller. Everything else is stock.

car probably came with a test pipe. you need a fouler :D. you should get an obdII scanner to see what the code you are throwing is. it is most likely that your car came with a test pipe.

correct me if i am wrong, but a dealership probably cant sell a car with out a cat on it. unless they shady. which is cool then i guess.

cel can mean a lot of different things.. Not just a cat problem. Having a testpipe, or a failing cat. converter is only one of them. Best thing to do is Find someone with obd2 sensor and it'll help you narrow down the problem.

good luck.

EASY fix pm me if u need help its a simple 5 $$ fix and a trip to autozone dont run your car with your check engine light for too long your sensor might go bad and its around 2 to 3 hundred brand new from the dealer!!..
