Best place to get 3.4 exhaust for 1988 GT? No catalytic converter, just muffler and pipes w flanges. From what I can see looking up from underneath, the bolts to the exhaust are OK. Pipes have rusted through in a few places. Hangers seem OK.

Would the 3.4 (on which the stock red "Fiero" intake manifold fits fine) exhaust be the same as the stock 2.8? Excepting without the catalytic converter.

Thank you!
John T

You can purchase a bolt on head pipe from the Fiero Store than can be used to delete the CAT (of course for off road use only). The remainder of the exhaust system can be fabricated using mandrel bends and straight pipe. Spintech can supply an exact size duplicate of the Fiero muffler. Its also non-restrictive and sounds good.
