Motordyne Shockwave Exhaust (pics added)
Well i got my motordyne exhaust installed and dyno'ed the other day. The prior exhaust was a Tanabe Hyper Medalion with a Tanabe Y pipe. We dyno'ed the Tanabe first, swapped the exhaust and had it back on the dyno in an hour. The only difference in conditions is that it was 4 degrees hotter outside for the dyno on the shockwave.
Impression, well first off just looking at it in the box, definate WOW factor. Second the welds and craftsmanship, night and day difference compaired to my old exhaust, Next is the fitment, well the Y pipe fit perfect no tension on the test pipes, the tanabe had plenty of tension and cracked a couple test pipes for me. Long term we'll find out if they get cracked. The Y back, perfect fit , fits the hangers as expected and no clearance issues, it fits in there close, but nothing touches and nothing touches under load.
Peformance, we'll let the dyno charts speak for themselves.
Sound, well its loud. So far everyone who has heard it likes it. Some say it got a sportbike sound but so much deeper. All say it still has most of the standard VQ sound. Personally i love it , but IMHO its a little to much for my DD, i will have the next tail section when MotorDyne gets it on the market. One V band clamp and its swapped over. Personally i'mm going to run the quieter VQ muffler on the street and the Shockwave track use.
The Dyno runs were performed at http://www.silverstatemotorsports.com/ , they were sceptical and thinking the exhausts would be within 3 Hp of each other.
The exhausts can be ordered from http://www.motordyneengineering.com/
Mods to car, DC headers, Megan Test pipes, Kinetics V+, JWT flywheel, JWT popcharger is about all for the power mods, i know i need to tune it soon, but will be done with FI later.

After watching the vids on youtube.com, you're right about the Shockwave sounding like a sportbike with a custom exhaust. The Vq muffler is pretty quiet.

I love the idea of this exhaust. I'm still trying to figure out if I like the look. Can you take straight shot from the driver's side?
I'm sure it sounds wicked

So.... it sounds great and adds 10whp over another aftermarket design, and you're hung up on the looks? lol
