| Exhaust question
Not new to this site, but posting my first thread. I have a 2007 GMC 2500 Duramax that is completely stock. I am looking into putting on an exhaust from the Cat back. I do not want to void my warranty, but would like a louder exhaust - if I could improve gas mileage, torque, or horse power, that would be icing on the cake. I like the sound of the 5" MBRP, but was wondering if I would need to change my intake. If so, what do you guys suggest? Or should I just stay with the 4" MBRP? I would appreciate any feedback as far as what make and size exhaust system (and what intake) you guys recommend. I don't mind spending a few extra dollars. Thanks in advance - can't wait to hear all of your responses! |
