Exhaust Dimensions

The only draw-back i can think of for the street would be that the first time you bottom-out on a huge speed bump or steep driveway you would most likely smash the exhaust.

a friend of mine has been running an aluminum 4" exhaust on his GT40R civic for several years with out any problems... downpipe and all and its standard thin wall pipe.
