I just bought two 1 chamber flowmasters for my 83' Trans Am and I was wondering what the best way is to route them for dual exhaust. I am using Hedman long tube headers and i have a 400 horse 350 small block, my tranny is a turbo 350. Please help!

 

Do a search on this site for Dual Exhaust and you'll find it. If you are dead set on doing dual, you're probably going to have to exit in front of the rear tires under the car with those mufflers.

 

Well, obviously youre not concerned with making too much noise, so why dont you go with the simplest way possible. Come off the collectors, run about 3 inches of straight 3" pipe, then connect the mufflers. Put 3" turndowns on the mufflers, hangers welded to the mufflers and bolted to the floorboard. My buddy has this on his 95 z-28, it sounds good and is very loud. I plan on running similar type exhaust on my car, but with dynomax race bullets.

 

here is a pic of his exhaust

 

ROTFL, is that gonna be LOUD!!

Sound Files!!

 

Cant, it will blow out the mic

If you happened to be at the '01 NFRA event, you would have heard this car run, and do burnouts. Jason Warren is his name, he won the LT-1 P/A class with a 10.10 at 137.7
