I just got my vibrant header installed and wow! it sounds awsome and theres a noticable difference in power, i'm running it with a magnaflow cat-back, its really loud at full throttle but under normal driving its a bit quieter. There was no fitment issues at all, very good header!

 

very nice, how long did it take to install?

 

about an hour

 

is it worth all the money?

 

any CEL? did you have a lift to do the install?

 

Wow. You're lucky. Mine leakes like a ****.

 

i think its worth the money, and no cel's and it was installed on a ilft

 

As said before. It is deff. worth every penny

 

I agree!

 

I got a CEL after I installed it on my SS/SC. It was previously installed on a 2.4 SS.
P0420 Catalyst efficiency below threshold.

 

That sucks any ideas whats causing that

 

The high flow cat is causing it. Catalytic converters are so restrictive because they actually filter out all the bad crap. High flow cats let more stuff through.

I emailed vibrant about it and theey said it was normal. So it looks like im gonna have to get dyno tuned. =) yay.

 

Still on the stock catback ?

 

Yeah I want to get a Corsa touring like the old setup I had on my 2.4

Is that not good?

 

I have had no CEL's with mine

 

alright thanks, i forgot to ask, did you get new studs and a new gasket, or did you re-use the old ones?

 

Get at least a 2,5" catback, but I'll suggest you the Vibrant 3".

 

no new studs re used the old ones with no problems and i used new gaskets

just got back from a little driving fun and still no leaks or cel's, i love the sound!

 

A 3" exhaust is overkill and its too loud. But thanks for the suggestion anyway

 

thanks man + rep given!

 

i got magnaflows cat-back with the header and its loud

 

just an update, still no leaks or cel's i love this header!

 

gah i don't know which to do, Vibrant Header or
Stage 2!!!

 

i would get stage 2 first

 

Dibs on your manifold,pm sent.
