I have the emission legal hooker headers on my GTA. It has some crap y-pipe though! I need to know if hooker makes a y-pipe to fit these headers, and if so, please tell me the part number. I want it to bolt to the OEM catyletic converter.

 

So, your headers bolt to the factory y-pipe?
The 2055 Hooker Headers come with a high-flow y-pipe.
Which model do you have?

 

the headers came on the car, I don't know the model #. They have collectors welded to some crap homemade y-pipe that is welded to the very end of the factory y-pipe to cat flange. I want an OEM style hooker y-pipe if possible, does someone make it? I figured they should have come with one too.

 

You probably have the 2460 headers, with a 3-bolt collector flange to a reducer, with this y-pipe welded to the reducer. If so, Hooker does not make a y-pipe for them.

Your only choice is to go to an exhaust shop and have a better pipe made. Those are good headers, though, so a good y-pipe with 2-1/2 down pipes to a 3" pipe at the cat, should work nicely. You should probably have the shop make a flange that bolts directly to the collector and just toss the reducers.

 

thanks dude, but will a stock TPI y-pipe work if it is modified?

 

That would be slightly more work than making a new pipe.
