Hello,

I will soon have a Gruppe-S Jet Hot coated Unequal-Length Header for sale.

The header is in excellent shape and already has a DEFI EGT Bung welded to it...

It is currently on my car...

This header will up both your hp and torque...according to a Gruppe-S test...just the addition of the header without a tune upped an STI by 11whp and 18ft/lbs.
They also concluded the following:
1. There is no low-end to mid-range power loss with the Gruppe-S 4-1 headers
2. Positive gains are achieved with headers, with NO LOSS on the 2.5 car

If you are curious on how it sounds, it's in between the stock UEL header and EL header sound...you will still hear the suby thump, but it will sound smoother.

It works great with a stock STI up-pipe...

New this was $499 plus shipping with another $99 added for the coating...

Let's start it off at $350 obo...lmk.

pm me if you are interested...

Thanks for looking.


BTW...the picture below shows what they look like new...the header is currently on the car and used...but in fine condition.

 

Updated some info...
