I have a magnaflow bullet in place of the LM resonator. It is loud at WOT, but its pretty decent when cruising.

TSP True duals, removes the bullets that came with them, and installed Dynatech mufflers. Now it passes the Englishtown 90DB noise regs for Friday and Saturday racing...

Come on Charles, You must be mellowing with age. I seem to remember you rolling in at the track running slicks and open headers.

just stick some single chamber flowmasters in there after the bullets. make sure to flange them, so you can take them off when you want the old sound back.

Please don't put Flowstoppers on your car.If you want quieter power get the biggest straight thru muffler you can find and MAKE it fit under your car.
Thats what i did. And its quieter than most of my friends true dual cars.

I just put some moroso spiral flows on my car in place of the bullets in the TSP TD setup. I love them so far. Drastically reduced interior resonance...quieted it down quite a bit...gave the exhaust note a good tone.
