Go for the undercar exhaust. I pick mine up Thursday from Cobra Restorers. Mine is a street style though. When my car was originally built, the exhaust ran all the way out to the back. Then one of the previous owners had it terminated & kicked it out just in front of the rear tires (see my gallery). It used fairly flat oval mufflers tucked up between the inner & outer frame rails. Unfortunately the mufflers were pretty restrictive and reduced the pipe diameter down to 1 1/4' in and out of the muffler. The larger chrome tips you see in my pics were just for show. I do believe you'll need different angled headers & it may reduce your flow if you end up having to reduce the system's ID from what you have today. I guess you have to ask what flow capacity do you really need to have? The upside is that you will get the noise out the back & since you'll be passing most folks they'll still get the full effect as you go by. With this update, I was able to run 2" ID smitty's (pertronix) mufflers , so I basically have open dual 2" ID glass packs all the way back... According to Jimmy & Chuck that's what the original street's came with, so the sound should be more correct, and since my motor's not a screamer, it should be better than before, and still not restrictive enough to make a noticable difference in power output. Getting past the rear axle is the real challenge. I've seen folks run them down the sides, tucked up & over the axles when the car had inboard brakes, and with outboards, as mentioned above, & I've seen them run down the center of the frame L & R of the driveline and then around the pumpkin. I'll post some pics later this week if that'll help. Side pipes are nice, but with your junk tucked under, the lines of the car are more contiguous. Besides, your's and your wife's ears and ankles will thank you. Go for it.

PS: if your car's got stripes, go ahead and get rid of those too. IMHO, undercar exhaust only looks good on solid color cars... I don't think you find one instance of a striped car with undercar exhaust, even with all the permutations on this site.
