i m thinking about the draxas exhaust... i have a trd s/c and would like a little more performance and better sound... the question i have is: the draxas comes with an s-pipe and a catalytic in-line. does the new s-pipe delete the old cat? if i use this exhaust system with the new s-pipe and new catalytic, will i have the CEL come on? which is the better fix: o2 sim or that little pipe that moves the o2 further away?

 

u shouldn't get a CEL coming on. i have the cc catback with high flow cat and s-pipe, along with a bunch of other people, and i'm almost certain that no one has had the CEL come on because of the exhaust. tc has 2 cats-u're getting a high flow cat for the exhaust, the other one is attached to the header. u would get the CEL if u replaced the stock header with one of the aftermarket ones-then u can use the o2 sim or antifouler to get rid of the CEL

 

thanks for the info.... i crawled under there to change the oil and didnt even realize i was looking at the second catalytic.... i was mistaken in my thinking that there was only the one cat.... thanks again.... i will have to save my paper route money for the new shiny exhaust....!
