Hey Guys I'm trying to decide to put magnaflow mufflers on or another brand. I currently run straight 2/12" chambered exhaust w/o any mufflers . Any thoughts,the resonance in the interior is pretty loud! Thanks for any advice.

I have magnaflows on mine and am very happy. I've driven it for 2 hours straight and carried on a conversation with a passenger without any trouble. I run about 2350 rpm at 60 mph (when my tach worked). I really like the sound. And get a lot of compliments from others. :)

Vette(s): White '79 Corvette. It's a driver.

A few years ago I changed from 2 1/2 chambered to Magnaflows. I did'nt replace the chambered sections with straight pipes. I just cut the back of the system to accept the (Magnaflow) mufflers and installed them.

I really liked the sound over that of the chambered system!

I also liked to once again be able to talk to a passenger or listen to the radio instead of exclusively listening to the chambered exhaust.

(No offense intended to anyone who has a loud exhaust system. Just my preference).

Vette(s): 1976 Silver/Firethorn. L48, 4spd. Original 2 bolt, vortec heads, 9.4:1 CR, Speed Pro Cam: 224/224@0.050, 112 LSA, Eagle Steel Crank.

I have 2 1/2 true dual Magnaflows on my '76 and love the sound. I do sometimes pine for the cool idle of the chambered systems, but not sure I'd want the tradeoff of the noise at highway speeds.
