I am curious which headers people with dual cat y-pipes have installed on their cars. I have been told there are limited choices in comparison to the single cat y-pipe.

The car is going to keep the stock y-pipe but will have high flow cats welded in place of the stockers. To my knowledge this y-pipe is a 2 1/4 inlet.

Any suggestions?

 

If you're keeping the stock downpipes, it doesn't matter what headers you use. You're going to have to modify those pipes in order to attach them to the headers, so go with any shorties you feel like.

Now, if you're going to do this the smart way and dump the factory downpipes, then you're limited to Edelbrock TES and Hedman emissions legal for dual cats. They will have the downpipes all the way to the cats, which it sounds like you are going to replace. The downpipes that come with the headers will be highly superior to the factory pipes to the cats, so why you'd keep the factory pipes to the cats is beyond me.

 

I've got a set of SLP Tri-Y headers on my dual cat emissions legal (has A.I.R.) set up. Unfortunately, they aren't made any more. I found mine on eBay.

 

Yeah the stock setup is going on the trash for sure. I found some more options and it looks like I am going to go with Edelbrock's.

 

If it were me, I'd go with the Hedmans.

But, it isn't me.

 

i had the same problem.....i kept my duel set up and used the y that came with my 2055's. after i installed the headers i took it to a local shop to finish the y with new catco's

 

By that, did you mean the "Y" after the cats?

 

whats the summit part # for the hedmans?

 

66491, 68491 or http://www.hedman.com/pages/hedmanmain.html
Look under street hedders
Footnote 145 is what you want (dual cat ypipe)


hmmmm those part numbers don't show up on summitracing.com

 

68491 does.... but theres no description or anything.... you can add them to the cart....tho.... and will these bolt right up to the stock unit or will i have to get some downpipes fabbed?

 

Go to the hedman site and they have all the info on them... click on the word Footnotes to see what they all mean. But it should include the ypipe up to the cats.

 

I checked it out and it does state it includes the y-pipe to the cats. For $349 or so it really isnt a bad price.

 

yea i just checked it out to... includes y-pipe and everything bolts right up it says.... Thanks for the help!

 

five7kid pointed those out to me several months ago.... I didn't know anyone still made any dual cat ypipe headers..... I was wrong.
