I have a 2007 Lt 4.2 and I want to put an exhaust on it. But I want to be carefully about the sound. I dont want it sounding like some pos rice burner. Anyone have any sound clips of there exhaust setups

Get the Magnaflow cat-back. It is well worth the money, it sounds great, isn't too loud, and looks MUCH better than any exhaust shop special.

I think it was around $500, I got it off eBay and I made an offer with the seller and I also had a 10% off coupon. I think the normal price is around $600.

Does the catback affect mileage or engine performance? I have heard that these engines are picky when you try to reduce the back pressure.

This system is supposed to increase HP about 15 or so and I can't really say if there was any gas mileage increase, but I can say it didn't decrease any. I thought about the backpressure thing too, and I would imagine that's why they gave the system duals (because why else would an inline engine need duals for?).
