The y pipe and the headers fits very well and also works well with straight or angle plugs. These headers and Y pipe helped my car put down 533rwhp and a time slip of 10.4 @ 129.8 mph in the 1/4 mile. I am upgrading to another header, otherwise there is nothing wrong with these parts. Price is $475 or best offer I would rather not have to cut the Y pipe to ship. So local sale is preferred, but I will ship if needed.

 

Here is a pic in the car and time slip.

 

What's the y pipe sizes?

 

its the SLP Y pipe that came with the headers it has stainless 2.5" collectors to a single 3". l believe it is considered 2.25" pipe but it flows well. I also have a new set of gaskets for the collectors that I will throw in.

 

Please double check the size on the y pipe. If they are 2-1/2" to 3" I am interested. I think they are but I'd like to make sure. Thank you.

 

Seems to be 2.5" too me see the pics attached

 

Here is a 2nd pic

 

Put some digital calipers on a strait section of the Ypipe and measure that. (doing some research)

 

I do not have any.sorry Please do some research on your end. I made 533 hp to the wheels with these on the dyno jet at indianamusclecar.com. I imagine these should work great for most people.

 

I have been doing just that for many many yrs.
I have never seen a 2.5" SLP Y pipe for third gens and that's Y I'm asking.
And yes, these are excellent headers, I have 6 different sets of them.

 

Well this is a set from slp I bought them brand. New from them so they are the same as what you have then so i guess you answered your own question. It's not a exact science measurement with a tape measure. Sorry for any confusion

 

Want any more? haha
