My muffler has rusted out. I recently installed the Radix and love it for pulling my trailer. But if I am having to replace my exhaust, maybe I will get something that will enhance the Radix... I am looking for low to mid torque in the 2 to 4,000 rpm range.

It has a dual 2.5 in/out exhaust with a 3.5 tail pipe. I am not going to put on LT headers, but maybe shorties.. maybe nothing. Maybe hiflow cats???

I am thinking about dual 3 in/single 4 out muffler. But also I don't want loud... low to mid and no to little resonance in the cab. I want the scavenging to work best for towing 2-4,000 rpm range!!!

What do you think??

 

1 7/8 headers with 3 inch y pipe kooks

then use a diesel 5 inch cat back bolt in deal for you that will flow like crazy

 

2.5 duals with stock cats are fine for what you are doing with youre truck. You might as well get L/t's if you get headers shorties are junk.

 

You would love a Corsa. High flow that's bad *** outside and tame inside. A straight through flow design.

I really love mine.

 

sport or touring?

 

I have the Touring. It and the Radix whine go together really well. I get all kinds of complements on how it sounds.

The Touring is just a tad softer than the sport. It has a packing that is good for 350k miles. It's the same stuff used in the Corvettes and Cadillac performance cars but tuned a bit louder than factory cars.
You know they are not going to put those babies on the show room floor with in cab drone.
I enjoty my XM sounds with ease.

They have gotten competitively priced lately. Shop around for sure.

 

I replaced my Corsa sport with the touring muffler and it's all good with the family when we are together.....but I sure miss the sound of my sport muffler and Radix combination. The sound is "INCREDIBLE" but a little to loud with the family. I'm going to sell my sport muffler that is made for a 5.3L.

 

How much? First dibs!! PM if you like.

 

Get the corsa touring especially if you ever decide to get LT headers.
