I know its not going to be quiet but I'd rather have a quieter muffler.

Bullets and 1 chamber mufflers are both LOUD

Dynomax bullets here. They are pretty loud inside the car once you get above, say, 2500 rpm. Sound really nice, but you don't want bullets in your case because there are quieter mufflers. Look at some sweet thunder chambered mufflers maybe.

I'm running Dynomax 18" bullets and hate them. Just bought sweet thunders for a more aggressive sound.

I'd recommend Borla XR-1s or Magnaflow 4x9s if you want it on the quieter side. Mainly Magnaflow b/c they're great mufflers and don't cost nearly as much as the Borla.

Jet Hot long tubes, no cats, H pipe and Magnaflow 4x9 oval mufflers(part # 11229 3" in/out).

idle - Barely louder than stock but nice and deep
Below 3000 - Still just a little louder than stock but sound bad ***
Above 3000 - It screams.

Here is a short video clip.

I a running the Brola XR1's. I have had the bullets and these are 100x better. Not near as loud, perfect sound, no drone. Just a awsome setup.

im running dynoomax bullets, mainly because theyre cheap. my setup is 2.5" so noise isn't bad at all. sounds mellow at idle, and sweet at WOT

I've got TSP duals with the dynomax bullets. It's really loud but it's amazing how much it quietens the car down compared to no bullets at all.

I'm running single chamber flows, and theyre ok, but I'm going to step up to a 2 chamber. Getting old / living in an apartment is taking its toll.

Here's some PN's for you guys...

FLO-325508 11.5" long, 8" wide, 3" thick. 2.5 in/out 3 chamber
These sound totally bad ***!! Not too loud, deep as hell, got many many compliments with these. I never had a problem with ground clearance either, I had to remove them because when I switched to a 9" and a BMR torque arm they would no longer fit where I wanted them.
FLO-325408 8.5" long, 8" wide, 3" thick. 2.5 in/out 2 chamber
I'm switching to these next, I think I can make them fit with my goofy *** suspension setup....
FLO-325108 5.5" long, 8" wide, 3" thick. 2.5 in/out 1 chamber
I'm running these on my car now, they are extremely small and loud as ****! Theyre not bad at idle or in the lower RPM, and very tolerable on the expressway, (I have 4.11's and an M6) However when you romp on it in the upper RPM's they get somewhat raspy, which I don't like.

SWEET THUNDER!

They sound great on my true duals. Its the first exhaust Ive been completely happy with them. Ive had them for some two years ago now. They arent quiet but I didnt want quiet. I wanted a deep agressive sounding exhaust and thats what I got.

There's a soundclip of my exhaust in my sig.
