Dyno was done a mustang. theres your problem.

So what was the point of posting that link?

Please understand. We are not all you. Most of the premium performance mufflers are very close when it comes to HP/TQ numbers.

After that it is sound tuning and for many this is equally important.

Not everyone is after the "flavor of the month" muffler that happens to pull the best numbers on a who knows what combo.
