I see you have an LBZ, and adding a turbo back can make a truck throw a code. I have a California emissions truck, and the only time I would ever throw a code was when I towed a trailer a few hundred miles. You can run a tuner (EFI Live, PPE, Edge EVO Race) to eliminate the codes, or a finger stick will do that as well.

A 4" exhaust will be all you need, a 5" will do the same thing, it'll just be louder. Let me know, I have kits starting $259 shipped.

I got the 4" exhaust for our LB7 from Alligator along with a Chrome tip, looks great and seems like a 15-20 hp increase.

It is a little louder however the 5" would be overkill I would think.

I did the exhaust in one afternoon and all the parts were included besides the elbow grease and time.

Thanks Chad !

Hey Eddie, good talking to you today. As I said you can save your money on the intake and I would recommend the 4" to stick to your budget and still get the performance you are looking for. Check your PMs at RWHP:thumb:
