What can I say I like the sound. I don't want it loud. Neway... go to this site http://www.magnaflow.com/02product/xl/xlperformance.htm look at the 4x10 and then look at the bottom one with the single in duel out. Would that work?

do a search for mufflers...there were a bunch of clips around

there were some on mnbonnevilleclub.com too, but for some reason that page is down.


from what i remember
in general:
flowmaster was the loudest
then magnaflow
then dynomax

i have a flowmaster and very pleased with it. 2.5" in and dual 2.5' out....stock cat. It'* about the perfect tone and volume for me.

Each car with produce a slighty different sound, but if you find the clips you'll get a general idea

My magnaflow has a nice growl to it. I can shoot some new audio of it tomorrow if you want. I actually plan to tone it down soon with a cherry bomb as a resonator.

That has some clips of my car NOT in motion. The sound of it going away is quite remarkable. There'* another clip around here of me pulling away from a camera at night.....I'll try to find it, too.

Here'* the other one. Notice the sound is totally different under load as opposed to Park.

I have an expensive speaker system with good bass on this comp. And it sounds great, but I want mine to be just a little bit quieter than that. Yours is really deep. How could you dampin the sound a little bit?

Remember one important thing. Our cars are quite different. Yours will be quieter with the same exhaust components I have.

You have an L27, I have an L67.

If it'* still too loud, add a glasspack. That'* what I'll do, but it'* not bad in the car. There'* a mild hint of a noise with the windows up. More of a low grumble or drone.
