Test pipe with a 2.5" Qtec electronic cutout welded in. Unit takes place of stock cat and makes a WORLD of difference in a turbo app. Made my t3/t4 reach 20 psi 600(ish) rpm's faster. Never dyno'd with or without but i'd estimate a 20whp difference with the cutout open. The motor on the Qtec was replaced just 7 months ago so no worries there. The testpipe was just recently painted with high temp black paint. Great sleeper mod.- $125
Apexi AVC-R - $275 Its still in my car but i'll pull it out as soon as someone wants it. Works perfectly well. Front cover has 1 scratch in the plastic, doesn't affect performance obviously. I'm going to get rid of it and go with an old school reliable Hallman. Thx for the space.
