I'm working on a project where i'm putting a 302 into a little British MGB. There's not much room down there so i'm looking for a muffler that'll give me a nice, throaty, sound, but not too loud as the car will be a daily driven car. I don't need cats. One option i've looked at is running from the manifolds to an H pipe, then into 48" lengths of 2 1/2" chambered exhaust on each side. That will give me good ground clearance, but it's a bit pricey. Any alternate recommendations? Note that the gas tank is off center -- shifted right, so the best answer would enable me to either run both tips out the left rear or come together into one pipe that would exit on the left rear.

Some relevant info...
Motor is Ford 302 crate w/B303 cam, aluminum GT40 heads, Performer RPM, 600CFM carb
custom headers with 1 1/2" tubes into 2 1/2" collectors
Ground clearance is also limited

Thanks for any suggestions.
