I have an FFR replica and changed from side pipes to an under car exhaust system in 2006 for the reasons you mentioned: it is safer for my two girls - who were 7 and 3 at the time - and is also much quieter. I also like the look.

It was too big of job for me to do so I farmed it out to a local shop - Dr. Gas. I have a solid rear axle and they placed the counter-flow muffler tucked up behind the differential. They also notched my rear cross member and used ovalized tubing to maximize ground clearance.
