I ran the 4" MBRP exhaust for @ 8 years before it rusted out. I switched to the Banks exhaust after reading some specs on it. The MBRP had a throaty growl that I really enjoyed and you could hear the turbo like a jet engine on a plane. The 4" Banks exhaust is much quieter with no growl but there is no back pressure and exhaust temps are @ 200 degrees cooler at idle. I can feel the difference in my seat when I take off.
