I know I could, but that's 1 more mechanical part to fail. I was trying to keep it simple if I could get enough flow out of 1. Thanks for the input guys.

 

I run nitrous, but I have 3" single for D/D'ing and dual 3" cutouts right at the collectors of my pacesetters... it flows PLENTY...

 

I think a single 3" would be fine. It would be a bit of a restriction, but for simplicity it's probably just fine for what you're going to do. If you were out for the best times I'd go with 3" duals with an X-Pipe.

 

Maybe I will do the dual cutout deal. Still be able to run the corsa to easy out of the Sub. undetected in the morning on the way to work (4:00am) Thanks for the input guys.

 

If you run the cutouts you'll want to have a seperate tune for the cutout's or you won't notice much difference.

 

hmmmmm..... that sux Man I wish I could keep my Corsa, but it looks more and more like a true dual or a bigger single is in my future. I'm spoiled to NO DRONE. If the Corsa wasn't the size of a battleship I'd look for a used one and have dual Sports.

 

It'd be tough to get me to get rid of my Corsa. The system is about the most perfect thing for a truck to me. Modding up a Diesel Corsa system might be an idea though.

 

my truck would go about 1/2 point leaner with cut outs. the other truck i had did the same thing. i tuned it closed to lower 11's and open to higher 11's and did see a nice gain. maybe it would have been a hair quicker if tuned leaner when closed but it worked prety good that way.

 

That sounds good to me.

 

That would certainly be a good way to go. Tuning it just a touch richer closed up and have it be about spot on with them open. Did you find any difference in the timing that you were able to run?
