Hey guys if I was looking to replace my stock muffler with a sebring muffler what size would I need to get

Thanks in advance

 

Get a quality replacement muffler from Magnflow, great sound with the best quality. There muffler is 5"x11"x22" #16641 Google, you can buy it on line....Gary

 

If you have the money... You should get the HKS Hi-Power Exhaust. They are the best exhaust for the G35 in terms of sound quality. It has a very nice deep growl. Alot of my friends who also have a G are very jealous of mine.
