who has these and how do they fit?

what are the sizes of the piping on the y pipe?

i had flowtechs on another car and they weere **** for fitment

thanks

joe

 

Don't have them, but nobody else has responded.

The pipe is 2-1/2" after the "Y" with an adapter to fit the 3" cat inlet. Several members have cut them at the "Y" and put in a Flowmaster 3" outlet "Y", for a 3" inlet to the cat.

 

im running headman headers and y pipe fit is good on the headers.. the y is ok
2 1/4 to 2 1/2 and 3'' adapter.. at some pont i will mod the y to full 3'' at the back were it meets the cat i dont like the adapter..im happy with it..

 

These fit fine. I had to modify the y-pipe to make it 3", and to keep it from hitting my SFC's.

 

my headmans fit great little moving of things to get them in but all in all the headers fit well along with the y pipe. only problems you might run into are the cooling tube on the passenger side running down near the header(hard line) might touch or be damn close so you might have to bend it out of the way you definately dont want a hole rubbed in that. and second off watch for the y pipe hitting the oil pan the right adjustment itll clear if not youll hear a little rattle around there.

o and the ball and socket flange works great fits great and seals great too.

 

how is the clearence on the passanger side frame rail?

when i had flowtechs...it hit there very badly

 

Stock it wouldn't clear the SFC, i'm not sure if I didn't have SFC's how close it would have been to the sub frame. I'd just chop it at the Y part, and weld on a 3" mandrel bend there and connect it to your piping.

 

near the frame i dont believe mine hits there i havent driven or looked at my car in a while but pretty sure it never hit. all in all the headers and matching y are a great product and shouldnt be dissappointed.

 

are these similar to the 68460?

 

IIRC, 68460 is with the older 3bolt flange, 68470 is with the newer ball and socket style. 17470 y-pipe never had the part number changed when it changed designs, 3-4 years ago IIRC.

 

i have a crate motor with a deep oil pan. the drivers side of the "y" pipe didnt fit around my oil pan. my mechanics had to physically abuse the left side of the y pipe to get it in between the crossmember and the oil pan.
other than that they work fine.

i really want duals
