    Hello all.
    So about a month ago i decided to remove the mids on my m6. Though the sound is awesome, I found it to be waaaaaay to loud on start-up(envision waking the dead). Sounded really great once warmed up from idle to about 2800-3000rpm. At 3000 or more the sound was really loud and hollow/metallic sounding. Passing a car with your foot buried into the pedal on the right became a little too obnoxious for me and constantally scared the poo out of neighboring vehicles.

    Not wanting to go back to stock, and not wanting to spend the money on corsa, borla etc., I decided to go a different route with surprisingly great results. Had my local exhaust guy install a 12" louvered glass pack with the louvers facing away from the engine. The result? About 10-15 % quieter than the mid delete. Startup just a little louder than stock, and reduced the popping sounds as well. appears deeper sounding as well. especially at WOT. Very pleased

    glad it worked out for you-when my A8 is in sport mode slowing for a light it is plenty loud with pops and cracks stock-that's coming from a 2010 SRT8 M6 with Mopar exhaust-for me stock is almost too loud lol...

    The popping is awesome, why would you want it gone? Also, it's a HELLcat...it's suppose to scare people.

    Just did my mid-muffler delete. Holy shit, it really is loud.

    I like the volume so far, but not crazy about losing that low, boomy/bassy exhaust note. It is much raspier now. I'm thinking I should have done the opposite, rear resonator delete and kept the mids. Having done that before on previous SRTs, it sounded great and the low grumble remained.

    NO-WEEDS maybe a better option for those that wish the volume to be ADJUSTABLE! :D

    Well, cutouts aren't really adjustable. They're just either open or closed. And for me I didn't want to feel that slight drop in pull on the low end (I've had them before) and the sound would totally drown out the supercharger whine that I love to hear.

    One odd thing I have noticed on both drives since the delete, my car is running hotter and the fans are almost always on. I see no correlation between the muffler delete and engine temp, but it is happening.

    Hey you should check out the exhaust sims that timmbo created in another forum on here. Great video showing them. I'm trying to decide between the exhaust sims or the mid muffler delete. The sims pretty much fool the car into thinking the exhaust valves are working like should but they are fully open now. I haven't got my car yet should be here in the next couple weeks but I think I might pull the fuse or disconnect the valves and drive around like that for a bit as the valves default to the open position and see how it sounds before I chop the mids right out. I think with the valves open all the time it should give that little extra bark we all want without being too excessive. Just some thoughts! I'll see if I can post his vid to this forum or go check em out I believe the vid shows them installed on his scat pack.

    Has anyone deleted the rear mufflers? It would be nice to hear what they have to say. Also to compare sound of mid muffler delete to rear muffler delete.

    The rear "mufflers" are actually resonators.
    If you delete them you will get drone, especially with an A8.
    Went down that road with my SRT8.
    The mid muffler delete is the best bang for the buck, but it is pretty loud.
    That said I love mine.
