We got the R/T on the dyno today to see how the 3" MBRP exhaust changed the power level, and I have to say ... WOW. I had been running the MBRP 3" exhaust along with the Techco CAI and 85mm throttle body, but both of those were removed and the car was completely stock, except for the MBRP 3" cat-back exhaust. 100% stock = 334 rwhp MBRP 3" cat-back = 363 rwhp *** 29 rwhp gain *** Note: the same dyno was used for both runs, and two pulls with each set-up were done to verify the power gain. The stock run was performed on 10/6 and the MBRP run performed on 11/21 which was 10* cooler for outside temperature. Here is a quick pic of the dyno sheet I took with my iPhone (sorry for the quality, but I wanted to get you the 'proof' right away). The red line is the stock run, and the black line is the MBRP run. MBRP ... this is outstanding!! Even taking into consideration that it was 10* cooler out for this dyno run, a 29 rwhp gain on a cat-back system is amazing!! Last, but not least, here is a video of the run with my car stock except for the MBRP: http://www.tvbmc.com/play.php?vid=1085 Notice there is no flutter, and just an amazing, rumbly sound at cruising and WOT. MBRP, you did a great job with a killer sound, and strong performance gains to go along with it. Thanks, again!! P.S.

I am really pleased with the dyno results! It was 10* colder on this MBRP run than the 100% stock run, but otherwise the car was the same and pulled nice and hard. In MBRP's testing they got a steady 24 rwhp increase, with some pulls as high as 28 rwhp, so while I am thrilled with our results, I am not surprised at all. This is an excellent system, built by guys who do a ton of testing, research and put together what they get the best results from. We are going to be testing out something with the TCM to try and be able to pull to a higher rpm (we can't now because the transmission will shift into 4th on us at redline) and it will be interesting to see how the power band looks with a higher rpm band. More to follow!!
