My Formula came with dual exhaust. The original owner had 2 mufflers put in VS the tranversley mounted stock muffler. (2 pipes in 2 pipes out)

So is 2 better then one? I think the exhaust is 2" as well. 2 1/2 good choice?

 

Yah, 2.5's would be a good choice dude...

 

Oh, and Crowfoot muffler had the best prices in town when I shopped around.... full dual 2.5" set up for a little over 500 bucks.

 

I have a 70 TA and I have a flowmaster 2.5" transverse set-up on it,and it sounds awesome...i'd show you a pic but I cant post em

 

What Flowmaster do you have, is it a 40 series?

My exhaust is terrible. Takes this alomst 90 degree bend near the axle.
I think it was put on to accomodate the trailer hitch Betcha its costing me power.

 

no actually its a 70 series,its nice a crisp.But then again I have a 455 huffing into it...
