Re: Exhaust System
Don't get one is my advice. I had a magnaflow on my 5.7 and removed it after a year and OEM put back on. Throttle response is much better with the stock catback, and with all that noise gone (best unmod ever), I regained sanity and the sweet hemi revving is all that is heard.
There are other proven upgrades that will make it drive better without making noise, and (despite the popular cable show) loud does not mean fast. There's a lowered WK Hemi with big wheels and loud catback in town who went to run my stock appearing Overland last week. He was quickly left in the dust, along with all his noise.
