Did you hook them to stock manifolds or after market headers?

wow that seems cheap. Is the quality ok ? I might have to pull a 3rd shift and get this..I also see they have the ZR headers too..

Jeff - I think OBX is less raspy and more mellow, bassy sounding. About the same or less loud.

Kevin - next time in DC area you are more than welcome to drive my car.

MikeGolf - I am running OBX headers.

Corbusa - quality is as good as OBX. The whole system is polished SS.

Would they hook up with stock manifolds? Thanks for the help but for the price it makes you wonder. I will do the headers later in year but with the coating and everything, I'll need an exhaust system first.

Yes it will hook up to the factory system - at least it would have for my 94. Driver side will hook up with 3 holed triangular flange and the passenger side will mate w/ 2-3/4"diameter pipe (factory size).

I have a few questions about the exhaust systems .. The OBX system for sale, will it fit right in place of the factory system or is major mods necessary ? When I do get the headers is there major mods needed there? Especially to hook up from the header flanges to the new system? How does it connect to the cat(s) or resonator..
Which part of the factory exhaust is the most restrictive ? Are factory old cats hard to get or expensive? I was thinking of getting old ones to hallow out so it looks correct yet can breath.. Any suggestions is appreciated..
FYI I am working day and nite to get my vette paid off asap.. But when cheap good mods come available I'll do what I can to get them and set them back for later.. any and all advise it really welcome...
