Aha... the one "turbo" muffler that actually makes more power than straight pipe is a turbo itself!
BTW... I killed the rasp monster as well on my no-cat-havin' exhaust. The Borla went out and the YoDude 2.5-inch mandrel-bent stainless cat-back went on. All it took was a 20-inch case Dynomax Ultra Flo in the res position to kill the rasp.
Now it sounds like this:
MSDS headers, MSDS y-pipe, no main cat, 20-inch ultraflo, 2.5-inch mandrel-bent exhaust (sorry, Terry, could not get it in 2.75-inch pipe
)
