Cheap junk from China. Expect fitment issues, and even if it does fit correctly, expect it to crack and warp within a year.
So you think I should just put back on my original exhaust manifold? I have full mods from Stinger from the 3" downpipe to SS tips. I just haven't done anything for the manifold. Is there a good performance manifold for our T-Birds worth buying?
The stock manifold isnt really that bad unless you are planning on really big power or going to a way larger turbo with a different bolt pattern than a T3 or IHI. You could port the E6 manifold you have, or see if you can find a used Bobs "big log" manifold, which are known to last nearly forever. There are good tube headers out there, but be prepared to pony up around $400 or more for them.
I think I'll try to port it or clean it up.
If you are after looks, you could always clean up the E6, smooth the exterior out a little, and have it ceramic coated.
