Ok, I've had my magnaflow cbe exhaust matted to my stage 2 LGT for two years now. Love the rumble, but at highway speeds it can get a bit drony (if thats a word) especially for those in the back. Recently I've moved and have doubled my commute time. Due to the extra time in the car it gets to be a bit much for passengers and although he doesn't complain, I don't want my son to go deaf. So what to do? I like the fit and finish and free flowing power benefit. Like some other LGT owners with the same set up I am looking into adding a third muffler to the midpipe section right after the DP. At the moment not interested in swapping out exhausts due to the extra cost or going back to stock as I just hated it that way.
1. Magnaflow 11219 (14x9x4 oval) Straight through perforated stainless steal tube with packing. Other members have had success with this muffler. But two things that concern me. 1
: Due to the width you need to angle the muffler down (pictured
). I'm already lowered and am concerned with scrapping. And 2
: the sound reduction seems to be a lot. 75% normal driving and 50% WOT with no drone. Seems a tad drastic, I'm afraid I won't like it.
2. Dynatech 76-014302 (14x7x4.5) Straight through baffled (oxymoron?)
"6-8 dB" reduction. Don't know of anyone else that has used this and what to expect. I'd think it would be similar to the magnaflow but about %15 more noise given the less internal volume. (60% reduction, 35% WOT ???) 2 inches narrower that the magnaflow so it should tuck up under and keep things straight. Should have about 1.25" between muffler lip and driveshaft.
3. Vibrant ultra quiet 1142 (10x6.75x4.5) Straight through perforated stainless w/packing. Concerned it just may be too small. Classified as a "resonator" not a muffler...if that makes a difference.
40943 (12x7 7/8 x 4.5) $$$ A bit more than I want to spend. Could be too wide and need to be dropped.
40944 (16x7 7/8 x 4.5) $$$ A bit more than I want to spend. Could be too wide and need to be dropped.
40085 (15x5) Enough sound reduction? Kill drone?
5. (JUST ADDED)
Magnaflow (14 x 4) Perhaps not taking the volume down a lot, but will it cut the drone?
