New y pipe?
I want to get ride of the cats on my truck. can anyone tell me if this is not recommended because of mechanical issues or anything? YES, I am aware of the law but thats not really my concern. I would like to find a y pipe that doesnt have the pre cat or the cat on it. I'm thinkin about leaving the one on there and cutin the big one out. I got some 3' exhaust for it and i would like it to sound really good. If anyone could give me an opinion, or advice that would be great.

You could
A. Hollow the cat out thats in your existing y pipe and go from there. ( airflow may be affected by the "box" (area where cat once existed) but not there now)
B. Get a 85 or 86 302 y pipe from a junkyard that dosent have the cat built in.
c. Put headers on
I would go with the headers. I just put hooker headers on I got from a junkyard. Also put in an H pipe with dual flowmaster 40 series mufflers. They headers were like new when I pulled them. Cant say about perfomance havent driven it yet.
Good luck! -Mike

I am currently looking for the same thing. Look into getting a set of Y pipes from an F-250 around the 94 or 95 year. Those don't come with the cat's, but have a flange to bolt a cat up to. I'm going to get one of those pipes, but the flange off the back, and hook duals up to the pipes (If I have room to cut it off and clamp to it.)
