Whats the size of the Y pipe on a 97 Z28 V8. I am cutting the cats off and putting in straight pipe. So I need to know what size the pipe is so i can order that size pipe and get it expanded over the stock. Thanks

 

it is 2 1/2"

You would be better off buying an aftermarket y-pipe with no cats. It will be mandral bent and bigger tubing, and will flow alot better. Plus you can save the stock y for emissions time or when you sell the car.

 

Who said anything about selling the car this one if not getting away ever and we don't have emissions

 

I was just trying to point out somethings that maybe you hadnt thought of.

Its only a matter of time before you have to deal with emissions and if you are keeping the car forever why not do it right and get the most flow?

 

Dunno. What y should I get?

 

We don't have emissions yet. But give it a few years and they'll be pushing them again. I made the mistake of dumping my cats, now I don't know what I'm going to do. I might just sell the car and get something else.

 

The best one ive seen and heard about is the Borla Y pipe. Its mandrel bent and is 2 3/4" which is 1/2" bigger than stock and is supposed to add close to 8-10hp at the rear wheels.

 

Borla doesnt make an off road y-pipe for the dual cat cars i dont belive, its only for the single cat cars.

There are only a few options, have a custom one made, stainless works ORP, or a Random Technology ORP. There might be 1 or 2 others.

 

You know I think you're right Ive been looking around alot lately, but mine is a single cat 95.

 

Is the stainless works offroad Y pipe any good?
