I am looking for some opinions on my exhaust setup. I am currently running Stainless Works Long tubes with 2-1/2" collectors and y-pipe. I feel the small diameter collector and y-pipe is hindering some of my performance with my current setup. I was looking at some of the stainless offereings from Texas Speed and CalSpeed. Texas Speed makes 1-3/4" headers and 3" collector y-pipes that they say only fit 2WD (I have an e-mail to them). CalSpeed e-mailed me back last night and said their 1-7/8" offerings are discontinued and being redesigned to fit 4WD. My question is, if the Texas Speed can be "made" to fit, would they be good choice or should I wait for the larger CalSpeed headers due later this year?
