there are plenty of places to find some LT's for your truck....

most people, like myself, run the Pacesetter Long Tubes with the Off Road Y..... numerous places to get these, i think they are close to $440 + shipping.... ask Sprayd99, thats danny we get a deal on them...

or some people have other preferences, Moze, DAMNyankee, got a set of LT's but im not sure what brand, i know he was happy with his choice...

as for websites to buy them...

www.texas-speed.com
www.speed-eng.com
would be the website...

also Billy at TRT Performance can get them was one thing i heard... check those places, but i would ask around first, before i go out and get some.... word of mouth can be the best deal, and help you find teh cheapest place...

good luck on your venture
