I already yanked that pesky old resinator. Would there be any fuel milage / power advantage to chuckin the muffler out the door? (other than the awesome sound)

 

I would go with a 4" system with straight pipe

Rip from Source automotive sells a 4" system with no muffler

I think the much larger downpipe and bigger pipe is good upgrade.

 

who cares about mileage. cut that pesky thing off and enjoy the screamin noise that you can make. my 01 is str8 pipe ever since day one. i get 19, pen and paper figures, with an egde comp box. and driving like normal people. well i am normal but i have an extremly heavy right foot. i'm now piggy backing and don't get as good cause my foot stays in it. and remember



LOUD PIPES SAVE LIVES

 

doubtful you'll see any appreciable power or mileage gains by going with a straight pipe.

 

Straight Pipe it for the sound If it's to loud you're to old.

 

the resinator is the most restrictive part, thats gone already...

I'd say that if your looking for sound and power/mpg inprovement you can't beat Rip's 4" straight pipe kit for the money......

Source Automotive (look at everything but the exhaust systems are under the dodge tab)

 

go with with the 4 its worth the money
GO BIG OR GO HOME.
