Has anyone done true duals with flowmaster race mufflers? I was thinking of an x pipe to two one chamber flows dumping before the axle. I have never heard these mufflers, but can't imagine they would be much louder than bullets. Also, any problems with the car loading up with exhaust fumes with the exhaust dumping before the axle? I live in the Phoenix area and need the A/C, no driving around with the windows down all the time. Any sound clips would be great. Thanks.

 

My buddy has those one chamber Flowmasters on his drag car. To call them a "muffler" is a stretch, they don't muffle much.......lol. However the car didn't lose any HP with them. OMG, the Borla snobs are gonna flame me!! Wait I mean when he bolted on the Flowmasters the car stalled and wouldn't run.
