Oh yeah, I knew that but the LSJ ain't gonna see much more gains considering that you are replacing a 2.5" exhaust with the GMPP 2.5" exhaust LOL!
BOOOOOOO!!!!!!!!
i hate to be the bearer of bad news on a good idea, but:

And why do you prefer the IRL to the 'Balt?

I don't like the IRL more. I'd take either but i won't overpay. I'm waiting for the LNF SS to come out. As soon as it does the LSJ SS prices will fall fast.
What if i told you the dynomax muffler i am planning on using flows 900cfm and a comparable flowmaster only flow's 450cfm? Would you still prefer the flowmaster?

My last IRL was stolen after i threw 4K dollars into it. The insurance company compensated me but it's still a bitter subject.

yes the GMPP exhaust has been dyno proven many times.
I still scratch my head at why that magazine article is dragged up time and time again.
its been discussed and discarded multiple times already.
it was done on an automatic 2.4 SS Sedan,
it was poorly tested, and they had leak issues.

once/if you get this up and coming it could be worth it to mock up a mandrel bent version as well(if you have a mandrel bender) and sell a mandrel bent stainless version as well for those of us who want the better flow and live in rust-ready environments.
Are the exhausts going to come with a cat as well? From your posts I'm guessing it'll be a one-peice exhaust and no breaks? Might be a little hard/expensive to ship that way. Personally I'd sell it in 2-3 sections that bolt togeather but if it keeps the cost down to do it your way, more power to ya.

What i want to do is produce a kit that "Should" be welded by a shop when it's being installed. Could you do clamps? Sure but welding would be the easiest and fastest way to insure no leaks.
The first "Test" Pieces should be bent up early next week so i will keep everyone updated.

Awesome...I would be very interested. I still can't completely justify shelling out that much cash for the GMPP exhaust, and it's only getting more expensive.
This would fit up on a 2.2 with no problems, right? And how hard would it be to get it sounding similar to the GMPP exhaust? I know most of us don't want anything that sounds ricey, and I wouldn't want something that's very loud. That's mainly why I planned on paying for the GMPP exhaust, but the money and questionable gains couldn't finalize it.

hmm sounds like a legitimate project. id like to see whats gained and id like to know what its gained from. is the stock muffler very restrictive or is it the piping that sucks? lets see some results im very interested
