I would love some sound clips - especially with different muffler setups.

I have AR headers with Corsa Touring, and Kooks headers with a custom B&B exhaust on different trucks, soon an Edelbrock supercharger on the 11' platinum, with AR headers, not sure on the exhaust, I have another Corsa but may want to make it loud with another B&B, but I have no sound clips. Where are you located?

I have Kooks 1 3/4 headers with HF cats to stock exhaust. It is a little louder, but i have been complimented by all how it sounds when i floor it...

I have the GMPP 3" catback but dont want to install it for i will downsize my catback from my now 3.5" I couldnt see the gain benefits

you guys get a tune done after the exhaust? I am guessing it had to help MPG and power?

I did get a tune, but mine turned into a bigger pig than before...LOVIN the extra power and i romp it all the time...Highway with cruise control on and it doesnt drink as much any more...With CC off , i watch the gas needle move to the left as fast as the speedo moves to the right...

Also have a cai and ported TB, intake manifold, and heads for more air flow, cam, and now a Ron davis Rad......

I have two Engine oil coolers and it helps keep the temps lower during heavy hauling

We have been playing with the tune for over a year on my black 10', looking for the best gas mileage on our 700 mile drives to and from our other home, we can now hold the 4 cylinder mode up to 82 mph, it under 70 stock, this allows the mileage to climb well into the 20's on the highway, we are talking to a hand held programmer company that we work with now, of course this does nothing for the around town mileage which is still holding at 12 to 12.2.

I have the Kook headers 1 3/4" with MBRP catback on my 07. I"m still waiting on my tune. I had CELs even with the high flow cats. FYI, LPP and Thorley headsers do not work with our trucks. Incorrect Y pipe caused fitment issues.

All the Doug throley headers I have seen are short tube headers, they offer no real gains over the stock manifolds on the dyno, do they make long tubes?

They do offer LTs but you will will to custom miodify the y pipe to make them work so that's why I ending up going with Kooks.
