Here's a link to the product page. The design saves about 23lbs off the factory exhaust system.

Our second design will be similar to our street muffled axleback but will simply have no mufflers in it. Should be getting that mocked up sometime next week and tested out on a local FRS here perhaps the week after. Have a rotated turbo kit for the STi to design next week (HTA3586R w/ Tial 1.06 Exhaust Housing) or we'd probably be test fitting it then.

Here's a shot of the muffled axleback:

PM me if you would like more details. I can post some video up here very soon of the track axleback. It's surprisingly quiet, no drone in the cabin, etc. Kinda shocked us actually. Dyno wise, both exhausts made the same amount of power. Combined with our high flow catted 2.5" downpipe we hit 19whp at the very top end of the powerband with average hp gains in the 8-12whp range and torque right around the same amount.
