I'm in the process of having a 408 built to put in my TA and during that swap I'm wanting to go the dual exhaust route but I want something that isn't obnoxiously loud under normal driving conditions. The headers will be Kooks 1 7/8 race headers (no cats) and the tips I'm going with corsa clones 3" inlet 4" outlet, anyone have a suggestion on the mufflers? I want a good sound but I don't need it to sound like NASCAR in traffic... thanks

I love my sweet thunders. Bullets are loud, chambered are loud but sound the best imo...consider some borla, spiral flows, magna flows. You can't go wrong chambered though....throaty/pure muscle sound..I never thought my duals were crazy loud on the stock cam....especially warmed up.

i loved the sound of my dynomax bullets!!!

Sweet thunders sound mean, but very loud. I think they are even louder than the bullets.

I went with cherrybomb glasspacks... I love the sound but with a dumped x setup, it's loud under city driving. Cruising speed isn't bad at all.

What length sweet thunders are you guys running?

Also if you had to rank the following in your experience from quietest to loudest how would you rank them?

Sweet Thunder, Borla XR-1, Magnaflow 20" 14419, Dynomax Bullet, Others?

They are much louder.

This may be a stupid question but has anyone ever run a sweet thunder out of the x-pipe before the axle and then run something like a Borla XR-1 or Magnaflow bullet style muffler after the axle?

SWEET THUNDERS. Deep throaty sound in low rpm's that people will notice but won't attract unwanted attention(police). Then when you get down on it, babies will cry. It is the absolute best of both worlds IMO.

Buy my Sweet Thunders. I'm swapping to a different muffler.

LOL... The best way to explain the amazing sound of duals!!


What do you guys think of 1 chamber flowmasters?

What are you putting on now; going for something louder? What length are your Sweet Thunders? I'm getting rid of my Texas Speed Bullets in lue of something louder; possibly SLP Loud Mouth 1 Shotgun Resonators.

I was going to go with sweet thunders for my build when I get to it here soon. Now I'm looking into a set of the Borla Pro XS mufflers. You should check them out.

Rise, if I were you I's pass on the LM1 "resonators" as they arent anything but a bubbles pipe. It's just a metal straight pipe that's bulged. If I was you, I'd go with the 1 chamber FM's.

I myself will be going with a pair of MagnaPacks

dr whigham, what made you decide to get away from the sweet thunders for a magnapack. Is that the same as the magnaflow 14419?

Bullets sound like dog ****. Tames open headers just a tad not much tone difference.

1 chambers are slightly quieter but the quality of the tone is leaps and bounds over any bullet.

Loud does not sound good.. Sounding good sounds good.. If it is loud and sounds good it is a win win.

Are Borla XR-1s or Magnaflow part# 14419 chambered or are they considered bullets?

Those are bullets.

So what are my best options for a chambered muffler on a duals setup?

dr_whigham

They're considered bullets, but they have a LOT more packing material. The 1 chambers have none at all. They're hollow.

I'm going to dual 14419's and NOT the Borla's due to case size. The XR1's have a 5" case and the MagnaPacks are 4" cases.

Another reason is the Sweet Thunders actually have a 2.5" ID being that the total OD of the ST is 3". I think at my power level there's a few ponies to be had, plus I miss the bass and "tone" of the MagnaPacks.
