Im getting a set of hooker headers for my car and im wondering what I should do for a y-pipe. I was thinking about getting one made from an exhaust shop but I dont know what size I should make it ( 3 inch from each header into a 3 inch y-pipe or 2.5 inch from each header to 3 inch y pipe)? What have you guys that have custom made y pipes done? The car has a 305 TPI and im not sure if 3 inch from each header is a little too much.

 

You don't mention which Hookers you're getting. The Hooker 2055's, a board favorite, come with one of the best Y pipes available. You might consider them.

Im getting the Hooker 2460's. I heard that the y pipe for the 2460's is nice but the end of them is only 2.5 inches. Will hooker's y pipe for the 2460's still bolt up to the stock exhaust with it ending in 2.5 inches or will it take modifications?

 

I know of no performance Y pipes that will mate with an OE manifold.

I meant will the hooker y pipe bolt up to the exhaust from the cat back? Also what size should the pipes be from each header?

 

If your application is on the mild side, the hooker y-pipe should be fine provided that the header collector and y-pipe are at least 2 1/2 inches.
My earliest combination used a Hedman short header with a Hedman y-pipe which bolted directly to an OEM location Flowmaster cat back exhaust.
Except for constant collector flange leaking, it still managed to help in getting a 13.4 second time slip.

 

So I should just have a pipe made then that is 2.5 from each header into a 3 inch y-pipe?

 

I am also going to be doing this in a few weeks with the headers and y-pipe. What can i exspect out of this? Will it make my car louder? Houw much hp will it give me 10hp?
thanks

Any ideas as to what size since im probably buying the headers tonight and I would like to know what size reducers to buy?

 

Hey what ever you decide tell me what you got if you would and tell me how you like it!
