Exhaust system

I found a picture of an engine that this guy rebuilt and that he is putting in. What is the big thing that looks like a muffler. and getting a 3" D/P, does it connect on the top left where the pipe starts??? or do you start it below on the two exhaust pipes? If this whole thing doesnt look familiar i think this guy said it was a custom exhaust so i dont know

That motor is going into a rear engine car, Fiero.
That big thing is the muffler.
You can't compare a Fiero's exhaust to a GP's exhaust.

Hehe, that is kinda weird looking.

Yeah, he has custom headers and exhaust... it's impossible to say what he's got goin on there, and it would be impossible to replicate on a GP.

I was at a Pontiac show in Kissimmee a few months ago. Some guy redid top to bottom his Fiero and stuck the Corvette engine in the rear of the thing. Looked sweet (the whole car did too)! He did some nice work.

The Fiero? It's not the original engine.

L67 swaps are pretty popular for those cars. There was one at ACS running 11s, iirc. Stock L67 in a GTP = 14-15s .. stock L67 in a Fiero = 12-13s.

Edit for lysdexia.

Fieros are so lightweight, give them power and they fly. However, the only decent tranny for them is a Getrag, and if you're not careful you can grenade them with the power of an L67... let alone V8 swaps.

I think Fieros weigh somewhere around 2500 lbs.
