Hi, all.

I just got a 86 z28 for nothing but the exhaust system is completly gone except for the headers. My question is will a y-pipe from a 91 rs 5.0 T>B>I work on this car. it has a 5.0 T>P>I


Thanks in advance

 

any one????

 

stock y pipe w/ headers? Not w/o nig mods, and you'd be way better just having a custom y-pipe built. If you're talking headers to headers, then it depends on the type of headers...

 

I have the stock headers....

 

You mean you have the stock cast iron manifolds? If you do, measure the outlets on the manifolds and then measure the inlets on the Y-pipe. If they match, you're all set.

 

yea the cast iron manifolds. Is there a difference between years and t.p.i verse t.b.i.? I guess i'l have to messure them

 

I'm not sure I remember all the applications by the manifold they used, that's why I didn't mention it before. OK, I believe the TPI cars and maybe those equipped with the L69 used a manifold with a 2-1/4" outlet, where the L03 (TBI) and some others used the 2" outlet. I'm pretty sure your Y-pipe fits the 2" manifolds (that's what mine were) , but I don't know what your manifolds will be. That's why I suggested you measure it.

 

well necer mind I Just answerd my own question....It don't fit.
Apartenly this is not just an ordinary 5.o t.p.i. It is the ho 5.0 in witch case it make a difference in the way the pipe bolts up. I found one but it is specail order through Walker. $171 I hopeing someone has one laying around. Any way thanks for your help:hail:
