I've got a 4-2-1 header to a 2.25" exhaust pipe, a magnaflow high flow catalytic converter and a cherry bomb 30" glasspack. I think this is a good setup. I need to get a new muffler.

I tried a Flowmaster Delta 40. It was entirely too loud. I double-layer sound deadened the undercarriage around the muffler with spray-on sound deadener, as well as laid sound deadening tiles in the wheel wells and the trunk, end to end, then I sprayed more sound deadener in the wheel wells. Then a baffle broke loose after 6 months in the flowmaster and I needed a new muffler.

I am currently running a Cherry Bomb Turbo. This was the quietest muffler available at Pep Boys. This muffler is much quieter then the Flowmaster Delta 40. It is about as loud as I'd ever want to go with a muffler though. Also, I've been running it for 6 months and now, I can hear a baffle has broken loose when I rev to high RPMs.

I would like my next muffler to be quiet and be internally welded so that the baffles cannot break loose as easily. I've never impacted a muffler, but they keep going bad on me. I don't know why.

I'm going on a road trip across the USA soon and I would like to get my exhaust squared away before then so that I really do not hear anything in the vehicle. I've been tossing around the idea of slapping a small resonator on the area that cuts diagonally to the passenger rear side as well, is this a good idea? What should I be looking at for my next muffler?

 

have you tried a silencer? my dad uses silencers and it works wonders on softening the sound

 

Get the super turbo I picked up, cost me like 45 bucks shipped. Dynomax Super Turbo, I posted the part number, and you know how quiet it is.

 

Borla Pro XS or Dynomax Super Turbo.
From all I looked around, these are probably the quietest performance mufflers out there, no idea which one of them is better tho.
I have the Borla Pro XS (40364) and a glasspack with stock header, it's fairly quiet but I'd still like it even quieter.. Anyway, definitely a LOT quieter than the N1 knockoff i had before

If the small difference in performance matters, Borla Pro XS is straight-through so it's probably a bit better than the super turbo.

 

super turbo me likey

 

Placed an order for 1 Dynomax Super Turbo muffler from Summit Racing. it should be here on Monday.

 

hm, i have the same issue going on right now. not that my magnaflow is that loud, or low quality, it's great! but it's heavy and i want something granny quiet. i'll be watching this thread.

 

iused a magnaflow and i love it. i would definatly recommend for anyone looking for a deeper tone in their exhaust but it very quite at idle thanks to properly sized resonator

 

I get exactally that out of my setup. My cherry bomb glasspack and turbo muffler is very quiet at idle, but then as soon as I tap the gas, the bass resonates in my car, out of my car, and through my very soul. It needs to be quieter.

 

I used a few Dynomax super turbo mufflers on my Sentra. They seem to fall apart internally and Canadian winters make them rot out underneath. In the Sentras it did resonate inside too. I ran the 2" inlet version with Dual DTM tailpipes.

BTW: The Sentra only has 110HP
