Hello guys,

We here at Gruppe-S would like to introduce a Power Package for the EVO market!
The Gruppe-S Power Package #1 was designed to provide the best "power for the dollar" solution to entry-level power modifications. After extensive testing, we carefully selected a parts combination that will yield the maximum amount of power without sacrificing drivability, reliability, or your wallet! We found that because of the stringent emissions regulations in the US, significant power can be made with the stock turbo by simply allowing your Evolution to breath better. The combination of the Helix CEL free cat delete, downpipe, and cat-back exhaust system yields an incredible hp gain (15%!!) for the Evo. As can be seen from the dyno graph, with our Power Package 1.






Helix EVO Downpipe $270

Helix Cat-back $449

Helix CEL FREE test-pipe $139

Special complete Helix turbo-back introductory offer $799 shipped!

Please Hurry! This special offer will end soon! Please give us a call to order while supplies last!


Thank you for looking!

very nice

 

i had my test pipe on and my down pipe test installed before my accident and the cel light went off. you have to make some sort of bracket so the wires don't touch the piping if they do my car died twice and is wasn't fun. it actually blew a 20 fuse twice until we realized that was that was the case. so case in point make sure the wires for the o2 sensor r secure and tight, but why it blew a 20 suse sensor i don't know.

 

Is the $799 shipped price still good?

 

YES! Please give us a call!!!

Thanks!
