The cat-back system comes with a silencer to quiet down the noise. All the hardwares are included (bolt/screws, metal rod for removing silencer and silencer). See pic!

Thanks

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 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.

I can't believe I don't have the $$$ for this...the exact setup I want for only $748!
Maybe Santa IS real and he'll leave this under my tree
I won't get my hopes up, last year he didn't even eat the cookies I left out.

The cat-delete pipe will work w/ stock downpipe. 3" gaskets are included in the package. It will also work w/ most 3" cat-back on the market as well.
Thanks

This is definately a good first mod. I just got my car dynoed with my helix downpipe ,test pipe, and megan racing catback (very similar to helix catback) and I got 265hp and 266 lb/ft of torque at the wheels. 2 simple words....buy and it.
