'79rx7

I have the '79 with the 13B aggressive street port, i'm looking into a new muffler because my the inlet on the Racing Beat Muffler is smaller then what i'd like it to be... I like the way it sounds now, but i'm wondering if there is more power to be found with a different muffler... I'm just wondering what everyone can suggest for a good balance of power, without being just a straight through muffler...



Thanks

Shay



P.S. I'm running 2 1/2 inch pipe from the RB header back...

Personaly I run a 2 1/2" pipe into a flowmaster. It is one of the least restrictive and free flowing. just my .02 worth.

I have a question......With the exhaust on these cars, don't they require a certain amount of back pressure because of the way these engines work without valves, and there is a small overlap of the intake and exhause from what i know, that a totally free exhaust will cause more of the incoming air/fuel flow right out the exhaust port?

ya no, my magnaflow gives me a good tuned sound. ive always liked it and dit hasnt given me any problems

No, from the guys that realy race these cars, open that sucker up. I know one that runs a 3" x 19" exhaust.

How do rotaries sound thru a SuperTrapp tip? Got a sound clip?

How loud is it with the Magna? I think they are the least restrictive you can get.

My project (for now) will just have a dp, that's it.
