JBA Evol

 

Corsa....i have it on my supercharged silverado with long tubes and its not even noticable at crusie speeds. I also have it on my tahoe and its perfect at WOT but whisper quiet at cruise. PM me for pricing on whichever kit you decide on.

 

Corsa + longtubes + no cats = Ungodly loud at WOT

 

I just installed the corsa sport system on my wife's tahoe about 3 weeks ago. I am very pleased with it. You cannot even tell it has exhaust at idle or cruising speed. As you push on the loud pedal, well.....it gets loud, but not raspy or obnoxious and no drone.

The quality is top notch and it was a breeze to install. I bought the kit with the 4" dual tips out the side. It even utilized the factory exhaust mounts.

I like it so much, I am considering buying one for my Sierra.

 

how is it at part throttle and idle

 

thanks for everyones opinions JBA is the only one ive never heard of sounds ike its down to that, corsa, or the longer magnaflow muffler

 

I have a radix, corsa sport, and dynatechs with cats and its not ungodly loud at WOT.....and its really really mellow at cruise.

 

Cats make a whole lot of difference in the raspiness and overall db's the exhaust puts out. Im just sayin that the LT's with ORY and Corsa is loud. Corsa is great for a truck with cats or a bullet installed, but crazy loud without some type of resonator/cat. I'm pleased with the JBA's mellow sound. It should get a lot more aggressive with the LT's and the ORY.

 

maganflow gets my vote. i put a stock size case one on my tahoe. the wife didn't even know i put it on till it broke in. its got a deep rumble in town and quiet as stock on the highway.

 

I have a magnaflow 18in case dual 3in. in / 3in. single out muffler. Got it from summit racing equipment online. It is deeper than stock and has a nice rumble when you get on it. I wish they had the same muffler with a 14in case. I would like it a little bit louder. I too have a ls1 z28 w. texas speed true duals. I could get two 14in. single in and out mufflers and splice them into each pipe and run tubing out the back or sides. I would probably add a magnaflow 3in. x pipe before the mufflers to balance the sound. That would be the ideal magnaflow setup and much cheaper than a corsa or prefab purchase.
