But I do have a Corsa Touring edition single side exit.
I am the most picky person I know when it comes to in cab exhaust resonance. I will not have it!
I would not have the Corsa had I not seen it on an 04 truck in the dealership showroom. They dressed up a new truck with 20" wheels and a Corsa Touring. I got a demo ride and was sold. You just do not hear it unless it is laboring or when you stand on it and then it is tolerable. The sound when under a heavy foot is unique to any I have ever heard. A hyper, throaty roar. I love it. While there I did hear a Sport dual rear exit and it was totally different. A raspy sound I did not care for. The Touring flows the same. It has additional perforation and packing. A material that will not show signs of deterioration for 300K miles. The same material in the Cadillac CTX exhausts.
As for true duals, they are not the optimum. A cross over pipe has to be involved for balance to get the best from it so it is not really true duals.
The Corsa muffler is a straight through design with sound porting. You can roll a tennis ball through it. It really flows very well. The pipes are quality bent and big.
Since the install I have noticed no change in MPG under normal driving habits. I have noticed the power pulls better from mid to upper range rpms.
The 05 trucks have more torque management then ever before. This will change very shortly for me.
I have the 310HP L33 H.O. 5.3. It is supposed to be the early SSR motor. Questions on this engine is what brought me to this site.
With a K&N drop in element and the Corsa she pulled 267 HP & 288 TQ on a Dyno-Jet dynamometer in Marietta GA last month. This was a Base run before installing an intercooled Magnacharger Radix blower. It is being done as I type. I get the truck back Saturday. You guys contemplating a Radix may want to check back and see the final run results. Magnuson claims a 120HP gain. I say 90. We will see.
I can post it when done if you like.
See my dyno chart below. It will be updated within a week from monday 7/11/05.
