Im planning on building a new exaust on my 87 IROC.
Im am planning on having a set of full length headers going into pipes that go straight down the middle and end at the axle. There will be a set of chambered mufflers on there as well and maybe 2 small high flow cats.
Pipe dia will be 2.5 inchs.

I need a good set of cheap headers, chambered mufflers, and the cats.

Any recommendations are welcome, thanks.

 

no advice?

 

You mean like it will be loud in the passenger compartment, and since it doesn't exit beyond the passenger compartment it would be illegal in all 50 states?

There's also the matter of the torque arm being there. And not enough room under the car for a muffler unless you don't mind them hanging down and hitting anything on the road higher than a snake.

 

i dont care about it being legal and im using the mufflers GMMG uses for 4th gen cat-back. I really just need a good set of headers the will work for it and not be pricey.
