[QUOTE="Jesse@MBRP, post: 10014861, member: 18263"] Exhaust systems on this car are really more of a supporting modification, as they are with any vehicle now days. Note the second picture above, testing shows that while at the stock power levels, the exhaust can get away with being nearly flatened and restricting flow, if you up the power levels just 10% (55bhp gain) that small section robs you of nearly 14rwhp over that of a fully mandrel bent section in the same diameter. Increasing the tubing diamter from 2.75" to 3.0" has an exponential power increase over those numbers. I've also got VMP tuning for my car and have baselines (stock pulley) vs. our standard street kit shown here. Running just Justin's tuning I was able to grab an additional 10rwhp over my peak gains with the stock exhaust system. My next round of tests will be with the stock catback and this kit with a 2.6 upper and VMP tuning. My thoughts that when boost is increased the gains over the stock system will be that much more.
