mufflers ?????
« on: July 13, 2009, 06:16:47 PM »
Hi
I need some advice on mufflers
I've got a pair of 50 series flowmasters behind a mild 454 with stock manifolds, a typical 2-1/2 inch system and the DROAN inside the car @ around 2500-2700 (cruising) is pretty bad !
The mufflers sit right under the seats in the typical place.
I've added an H pipe and resonators with no noticable difference.
Can anyone recomend a muffler that will shut this thing up inside and still have a decent note ?
Cheers
Dave

The mufflers arent hitting something (crossmember?) causing the droan/vibration??? because the H should have fixed it????

No, all that's o.k.
It sounds fine untill you hit 2500rpm then it resonates through the cabin untill about 2800rpm then quiet again.
Muffler shop says tripple flows (turbo) mufflers will shut it up.
Anyone got a similar set up, they're happy with ?
