I don't know about the 3" o2 pipe, since I am going to get s3, eventually, I decided not to do it since it isn't compatible with the s3 manifold.

I can say that a 3" dp made a big difference. After that, adding a 60 mm tb finished off the airflow nicely.

 

Sweet thanks for the info... i think i will be doing the downpipe + mopar catback.. i have to get a new exhaust system. Any other exhaust suggestions?

 

has anybody else put on the extrude honed intake manifold on there car seams like im the only one here who has it.[sm=feedback.gif][sm=feedback.gif]

 

You're the only one I know so far, black4. I may be there with you soon, though. Just trying to prioritize my mod schedule - It is in there, though.

 

Same here, it's on my list, I just need to get the money for it now.

 

rr if you get it do the t/b at the same time you wont believe the difference.

 

It really makes that much of a difference?

 

you know how it felt when you went from stock to stg 2 the throttle response difference know imagine the same step up in throttle response again it eliminates a huge bottle neck much better power below boost,not to mention it spools so quick now its hard to stay out of boost. highway pulls in 5 gear lets just say even going through the moutains i dont have to dowshift out of 5th gear any more.

 

That is tempting. I found similar results with just the tb, I wonder how much the manifold does. 630$ is a chunk of change, though. Do you know of anyone who just did the manifold? I would love to hear about that experience.

 

im the only one i know of so far but remember you get 200 of it back when you give them your old manifold.
