borla or magnaflow mufflers blown 340 3" or 3½" ?

Mshred: that sounds just right,truly the sound of a healthy motor,brings me back to late summernights watching stuff wish is not entirely legal.. will use the longer ones on my build for sure ,i cant remember your motorbuildpecs but i seem to remember that my build is slightly more agressive and that i may need alitle more mufflerbodyvolume to tame it down alitle, hope my car will sounds as mean and healhty as yours!
is the soundvolume in the car ok while driving?

BTW i also whant to thank Steve and Don at Borla for the time and advice given,top of the line people!
