nope, i found the problem, the "newer" glasspacks dont "blow-out" like the old ones, it was a pesky exhaust gasket leak.... but ive since gotten a new titan....

yea i have one on my 92 toyota 3.0 it has headers and an high flow cat but thats what you expect for only 25-30 bucks for a muffler i have the dynomax thrush also

The main reason is because that after a while the glass finally melts so the sound changes.

its because it takes a while to blow out the excess fiberglass bits thats left in during manufacture

uh that sounded horrible after 8,000 miles.

much better
