Re: exhaust
The Corvette rams horns were available with a 2.5" outlet. Originals are getting rare......I don't know if anyone is repoping them.

Re: exhaust
The old Iroc-Z's had a 2.5" outlet on them IIRC.

There's some now on ebay... http://cgi.ebay.com/ebaymotors/Corve...mZ170253511649 If that link doesn't work (it's long, myabe won't survive), here is the item title: Corvette Chevy 2 1/2" Rams Horn Exhaust Manifold Impala Then there are some interesting variations, like this stainless steel set with a more graceful curve than the OEM design. http://www.speedwaymotors.com/p/5425...Manifolds.html |

Re: exhaust
If his castings are any good that is a good deal. It looks like he has machined the surfaces and threaded the stud holes.
By bad castings I mean low quality steel, voids (air pockets) or thin walls. Result is warpage, breaks or leaks.
