So I'm ordering a few new things for Christmas and just wanted to make sure these will be smart investments and actually help.

1. Stillen Headers
2. Stillen Grounding Kit
3. Unorthodox Racing Crank Pully

Question: does the Stillen Lightweight Aluminum Flywheel work for automatic transmissions??

cant wait to get the new mods and as soon as I get them in and install them I'll post pics up

thanks,
Chris Cary

I'm not a fan of Stillen, but the flywheel is only for manual transmissions.

Save your money on the stillen grounding wire set. BlackBetty on myG37.com makes better kits for less money. Here is a link to the ordering information.

The UR pulley is debatable. The cost of the pulley and installation vs the improvement is kind of hard to justify.

Headers are decent....but looking at the sale they are having now, it would be hard to pass up...

+1 on the Black Betty's
