			A few years ago my GTU made 131rwhp, that was with RB pre-silencer an mufflers and a mild port job, A/C components removed. S5 engine btw. (I can't really remember if I had the RB or if I had the stock exhaust system on when I got it dynoed. The time I put the RB exhaust on was close to that time.) Since then I've removed the emissions components, 5th & 6th port actuator sleeves and rods, wired open VDI. I've mentioned this on the other forum, some will argue this, but I did notice a difference with the sleeves and rods removed. Mainly: smooth, all the way up the RPM range. Low end: no difference. I might get It dynoed again in the spring after a needed tune-up. Id like to see what its been making.
