Im ordering a Dezod S2 Turbo kit very soon for my 08 tc, and i had some questions about the downpipe option on the kit. The 2 options are Off Road Special Catless downpipe and a Catted downpipe. The Catted downpipe is $150 more and some of the questions i had are as follows :

Whats the difference?
Is it worth getting?
Pros and Cons?
Sound/Performance difference?
What do most prefer?


Thanks for the help!!

 

Whats the difference? Off road catless is a straight downpipe but catted has a filtration section that should keep you from throwing a catt efficiency code.

Is it worth getting? It's personal preference your choice.

Pros and Cons? Catted will let you pass emission test if you have to take one

Sound/Performance difference? Catless will be louder when you get on it but a high flow reosonator should help you. Performance wise not really sure how much hp you'll lose if any running a catted over a catless.

What do most prefer? Most prefer catless

Hope this helps you a bit. Go to youtube and watch some videos to get a better idea of what catless turbo cars sound like.

 

This man hit the nail on the head for you OP.

 

Thanks Paul just trying help out.

 

catless ftw

 

Go catless, if only just to throw flames.

Its worth it lol

 

If I could throw flames AND not have a CEL, I'd be in heaven. lol Hell I even had a CEL with the catted downpipe.

 

Yeah I had a (used) catted DP for a while, but still threw a code.

After further inspection there wasn't anything even in the cat, so I'm not sure if a real catted DP would throw a code

It never used to throw flames tho, up until this summer. Now it throws em everywhere haha I love the look on peoples faces

You guys are awesome! I really appreciate the help! Definitely going catless then.

 

For those of you guys using catted downpipes, how are your AFR readings on your wideband? wouldnt the cat mess up the accuracy?

 

I have done sensors before and after a cat, to be honest, on a Random Tech cat, the readings are minimally different.

 

Is that why it still throws a code? haha I have the Dezod w/ catted dp and could not get my CEL to go away. I ended up having to take the kit of to pass emissions (even though technically I was 'legal').

 

What year is your tC?

 

'07

 

catless. Went with a random tech cat on my S1 kit years back, would have gone catless if i could do it over.
