I will be purchasing an exhaust once I get my tax return.. I tryed a search and didn't find the information I needed to know.

Does anyone know which exhaust system throws the CEL? I'm looking for the best performance gain with no CEL. I'd also perfer a bolt kit system but I will bring it to someone to weld if needed.

 

which system would you want to know about? Our systems for the tC do not turn on the CEL when it is installed. We have tested it already. :D

 

Has your cat back been dynoed if so what were the results?

 

Yeah the catback was dynoed, but I want to dyno it again. I was not impressed with the shop that we dynoed our vehicle at. So we are gonna dyno again at another shop with high regards. Better to have a newer dyno run our car than a 10year old one. :?

 

So, the dyno numbers weren't good then...

 

Not to my liking, and on top of that. The dude dynoing the car was new at it! I had to tell help him out on gettin the car started on the dyno.

Time to redyno the system/car. (sigh)

 

you won't see much power/if any power gains with just an exhaust. you'll need at least an intake, and a high flow cat or test pipe would be even better. but high flow cat or a test pipe will throw a cell. race headers help alot to

 

What the heck is CEL?

 

check engine light...

and the precision muffler.com tc exhaust does not trip it..i have it on my car

and its the best..

 

seems like i'll be going with precision muffler..

sctiontctrav, do you have the full system? (did you replace the cat?)

 

Yes..I do have the Full System. From the Downpipe back..no it came with a resisnator...the cat is removed.. which is what give your the horsepower..only flaw is its not street legal.

 

I had my system custom made from the header back. Straight 2.5" pipe with a aerospeed muffler. I'm ordering the DC Sports headers soon. :D

 

With the DC header your car is going to be SO LOUD!!!!!!!!!

Anything from header back shouldnt trip a CEL. The 1st cat should give enough backpressure to fool the o2 sensor. Once the 1st cat is removed is when the CEL comes on.

I'll definately be going with the full system since it doesn't throw the light.

what type of WHP gains is everyone getting from the full system?

 

Im not quite sure yet..I wanna guestimate around 8HP But I havent Dynoed mine.

 

The dyno that we had was about 4-6+HP. The + is when you add CAI or more. :D

HeHe! It's not so bad right now (either that or I'm used to it!).

 

Yeah that system is going to be srceaming for a ticket!

 

If you lived where I live you wouldn't be worried about that
