Glad I could help. I haven't bought these myself but a friend of mine did and he said they installed and fit just fine. He drives a NNBS silverado so I don't know if that's of any help. Lol!

 

Too me it looks like theyve got more room to work with tho in stock height that is at least. I hope mine isn't a bitch because its lowered lol not even gonna attempt put pics up on this site. Their all on ls1tech lol

 

if you don't need cats & are looking at 1.75", just get the stainless ones off eBay for $300.

 

I saw them and looked at them, I went ahead and chose the pacesetters tho

 

I just put the long tube set up on my rig, DO IT, YOU will love it.
Even before my tune it has a lot more grunt off the bottom end, and the sound with a off road y-pipe and flowmaster 40 series, sounds like a 70's chevy muscle car.

just make sure you check fitment for your dipstick tube and spark plug wires, had to cut my oil bracket and extend it, spark plug wires are for now held in place with Zip ties till I get some 90 degree boots or wire separators.

 

Damn I already bought them lol the ones someone posted a link of in the first page from Texas Speed. I asked around and they say it fit nicely and didnt have to modify. But some say they do, Iv noticed that with the pacesetters its either hit or miss with some people when it comes to fitment. I do already have my exhaust coming out the side with a blowmaster (no offence but I know they suck when it comes to performance, but sound damn good) super 44 I put on there almost 4 years ago. I will make another thread right now about my exhaust tho
