What kind of power gains is everyone seeing with the pacesetter longtubes on the 5.3's? also, is there any other company making the lt's comprable to price and quality of the pacesetter?

 

10-15hp with long tubes (once tuned)
no, Pacesetters (most affordable) are the budget tubes.

 

Thanks, thats what I was thinking but i've heard of some guys saying there not gaining anything and some guys saying upwards of 20 horse.

 

All depends on you tune and supporting mods!

 

I just put mine on this weekend and without a tune it picked up two to three tenths. Done on a Gtech, so take it with a grain of salt.

 

are the pacesetter's compatible at all with the stock cats? or just 86'em and run the ory? I know the arizona speed and marine lt's you can still run stock cats but im not sure with the pacesetter's but im not going to spend 800$ either

 

If by compatible you mean will they bolt up to your factory y-pipe the answer is no. LT's are much longer. You can either build a Y pipe with your cats in it. or just run an ORY.

 

Thats what I did just had them cut up the stock Y pipe and put the cats in....

 

i lost 3 tenths in the quarter mile with just the addition of Pacesetter LTs and their ORY.

 

Did you tune it?

You'll be running rich without a tune.
