    Loudest Muffler

    I'm going to change my exhaust this fall...I'm tired of the over the axle shit...I always have my cutout open, so there is really no point of me having the extra weight of my muffler, plus it squeaks. I plan on doing true duals dumped before the axle. I've grown very fond of my excessively loud exhaust, and I don't want too much of that sound through the mufflers (I'm not going to have cutouts this time around). I was thinking glass packs...they're relatively cheap ($20-$50 depending on brand) and seem to be the loudest I can get while still maintaining back pressure on the exhaust valves (no mufflers would be the loudest)

    Anyone have any suggestions for a muffler that sounds like it's not even there?

    Not really a muffler, more of a resonator, but the SLP Loud Mouth

    loud mouth is loud like it implyes but if you want to save some money you cant go wrong with a set of Summit bullet mufflers, they are right around $18 each

    I agree with the 1 chambers, very deep and a clean sound. The chamber eliminate alot of the rasp associated with some bullets.

    I hate all Flowmasters except zsingle chambers. They will sound the best. Glasspacks suck so much ass it's not even funny.

    Sounds like you are talking about what is on my car in a way. I have a 4" single system that was custom bent(mandrel) by a shop in MI. 4" back, over axle, threw a spin tech muffler.

    Sounds great IMO. Zero rasp.

    Avoid glasspacks.


    I had some $25 bullet's on my over-the-axle duals before getting the Magnaflow mufflers on there.
    Sounded great, and was quite loud. I prefer a more tame sound compared to most.
    Take a listen....towards the end of the video, starting around 1:45.

    I would stay away from flowmasters, they sound great but have poor back pressure. Flowmaster imo are the worst exaust for an LS1.
