I will try and get a clip ... the muffler is good enough to flow (single muffler) for an engine of 222hp, according to the local dynomax dealer.
Its funny, I don't know if its the angle on the exhaust tip, but I was showing some friends what it sounded like, and I was on a gravel driveway.
When I revved it, I blew a small crater in the gravel right under the tip... you can really feel the BAS Header/Dynomax muffler flow when you put your hand under the tip.
