Honestly, I bought a flowmaster universal catback kit from Jegs or Summit. It came with 6 or 8 nice thick mandrel bent pipes in 90* and 45* bends. I just had to do some cutting and welding. I used a magnaflow 3" X. I did find some local exhaust and performance shops with some pre-bent pipe, but they weren't the same thickness.

 

Mine can get loud at times.

I have pacesetter LT, 2 bullets, Magnaflow dual 3" to a single 4" out in the stock position.

Thats on a CCSB 4x4 1500HD

I do have some drone at some speeds but around town its not to bad

 

Thats the same magnaflow I tried (without bullets). Nice deep and mellow and works great with the radix.

I had mine setup with a 4" dump, which didn't help the drone any.

 

Without the bullets it was much louder than what I wanted in a daily driver. when I added the bullets in it had a nice sound. and when Im on it, it still screams

 

Thanks for the info guys, I'll keep my fingers crossed for no resonance lol. I can deal with rasp. Does having cats on the Y-pipe keep the loudness down at all?

AP- Sorry for the late reply, what were you guys doing at Charlies?

 

heres a clip of my old setup. Mids,ORY and Flowmaster muscletruck exhaust

I've got to agree... You either need bullets or cats. I tried the magnaflow and liked it a lot until the RADIX came to town. The I took off the cats and positively hated it. So I went to bullets in place of the cats with the Magnaflow. Still hated it... but better power. Finally went to the Bullets and a Corsa touring. Seemed better... but still drone. I think the Corsa touring is the quietest aftermarket muffler out there for our trucks... but without cats inline as well... it can still be louder than you like.

My current combo is Dynotech long tubes with their high flow cats and the Corsa touring behind my 402. WOT is still loud and it still drones. Even with dynomat extreme laid from just behind the front seats all the way to the back door and up the side walls to the headliner! It's the price we pay... lol.

 

Thats wierd I had none at all, maybe its because yours is an SUV the muffler is under the passenger compartment. I had none whatsoever with the 418.

KB- Putting cats or bullets on will take away the rasp of it but wont quiet it down too much. The best way I can describe it is, that it takes the "bark" out of the exhaust note, the high pitched scream but its still LOUD. Me personally I love the lt, no cat and my corsa setup, I like it LOUD Its also nice when someone cuts me off I go to the left side of them and when that side exit gets right to the back of their car, punch it and watch their face as the tailpipe passes them.

 

Well I am running LT's, ORY, Dual 2.5" with Hooker Aerochambers and in the cab there is no resonation. At cruise and idle it sounds good at WO it is Very raspy, just put the LT's an ory on and I will be ditching the Aerochambers for a 22" magnaflow that I have.

 

Thanks for all the input guys, I guess I'll just have to wait and see once it's all done. Quik- the truck sounds sick in your clip.
