whats the difference between the Hooker Y-pipe on LS1 and LT1 cars?

The LS1 Y comes in a few pieces, i heard its so u can put cats on is this true?
if so does the LT1 Y come the same way ??

 

I think the LS1 headers and Y use the slip fit design whereas the LT1's don't, they use the flange design. Also, if you look at the LS1 headers and Y compared to the LT1's, the LS1's "kick out" more to the outside of the car on the driver's side. Would it fit? Maybe with some fab work but you would still have to use a flange adapter.

 

Hooker's LT1 Y comes in three pieces with weldable flanges and a dent/clearance for the tranny crossmember

 

anybody have pictures of each y pipe?

Not great pics of the Y pipe, but you get the idea. The 3 pieces it comes in are slip-fit, and the flanges you weld on yourself (the pipe is flared for them at the ends)
You can see the clearance in one of the pics above

 

I have the Random Technology Dual Cat Y-Pipe

Couldn't be happier, a nice easy bolt-on

I went with the Aluminized version due to the fact that the car rarely ever sees wet roads or salt, as It's my weekend car

I got mine from LS1 Speed (1/2 way down). The Stainless version is also available though most vendors if you like.

Sounds very nice mated to a Loudmouth with a Bullet Muffler

Hey Spinner,
Have you had any experience with the mufflex Y compared to the Hooker Y? I have a Mufflex right now and it drags on my garage floor as I pull in (car is lowered about 1.5") and I think that I am going to get a Hooker to replace it with since it looks like it gives a little more ground clearance.

 

long tubes are so hot , i cant wait to get mine

 

I think the better option would be the kooks Y pipe because it goes around the tranny xmember as opposed to under it like the hooker y. Mine's been good to me though, cant really complain. Fits better then any mufflex i've seen.

 

Ok, thanks for the reply.
