Flowmaster
Got this for my 2014 Ram 1500, sounds so much better than the stock single. Ran it straight out the back,but you do have the option to run it to the side. Sounds great,except on the highway in "eco" mode,but not Flowmasters fault. One pipe wouldn't slide into the muffler,but a little massage with a grinding disc solved that in 2 minutes.
'09 Ram 1500
That's what it sounds like when you install it on a Prius...genius. Ridiculous...."sounded like a Prius" This is an excellent product and sounds great on my '09 Hemi Ram.
Not worth the money
After speaking to a “specialist” about what I was going for and sound they led me to purchasing this and told me it would be a lot deeper and louder than what I had currently. And what do you know? I have a shop install it, all excited to pick up my truck after the called, and she sounded like a Prius. Do not buy this if you are looking for an aggressive growl the reps do not know what they are talking about.
