I am looking to get some LT's soon and I was wanting to know if the loudmouth with the dynomax muffler helps quiet it down and if it sounds good with the dynomax bullet muffler ?

I don't have headers but I have a friend with the loudmouth and I have the dynomouth. His car is clearly louder so I would say you should get a nice sound with the dynomax/LT combo.

By the way I still prefer the dynomax sound over the resinator because I have no noticable drone at any rpm range and his A4 is deafening at about 65 mph but then again he says the drone is music to his ears.

The Loud Mouth was designed for the best sound and performance on a car to remain mostly stock, so the bullet is a good idea to kill the drone that the LTs will give it. the resonator cant do it. I heard a car with long tubes and a LM, not sure what muffler exactly he used in place of the resonator, but it sounded good.

That is what I am wanting to get out of the Loudmouth and the dynomax bullet muffler with the LT's, Because that is what I have read people do. I just don't want it to sound bad. So if anyone else has seen or read about this let me know

I had a stock engine with stock manifolds with Loudmouth, and it was very loud and tinny, no rasp, and drone around 2200 RPM.

Then I put in LT headers and replaced the resonator with a Dynomax bullet at the same time. The sound got considerably deeper and louder, still no rasp, but the drone is still there.

Then I did a heads/cam swap and with with a pretty big cam, amongst other engine mods. Exhaust tone got even deeper, and more rumbly, not much louder, still no rasp, drone not as noticable at 2200 RPM.

Then I installed 100 square feet of B-Quiet Extreme in my car, and I can't hear the drone at all. With the stereo at a moderate volume, at highway cruising speeds, I cannot hear the exhaust over the music.
