just to warn you, those SLPs dont come with a y pipe, unless combo motorsports are making their own and no one has spoken about it yet, go to any site, www.thunderracing.com www.tbyrne.com www.ls1speed.com www.slponline.com whereever you go you will see they are just the shorty headers that bolt to the stock y pipe.

for that price i would buy those in a blink of an eye if it had a y pipe. heck , the mac dual cats with an offroad y pipe is 550 or so uncoated, so theres no way an SLP system coated with a y pipe and larger primaries is going for that price. lol

 

Thats what I was thinkin well here is a link...here part #SLP-30017C see???

 

hmm, it does say "includes y-pipe", maybe its time to call up CMotorsports?

 

pacesetter has lt coated headers for like 389 + 51 shipping.
