Are today's tuners on diesels reliable and trouble free? If properly installed, does more power negatively impact the longevity of a properly maintained engine? Thanks in advance. Mike
I put a turbo back 4 inch on my 04 and it is as quiet as the stock one. I use gibson exhausts and there is is no 'drone'. a friend put an exhaust on his dodge and it does drive ya nuts. His wife rode with us for a few miles and said it was so much nicer than the dodge quiet and comfortable.
They said about 7-10 hp gains are possible with the exhaust, but I run the OEM air filter so a free is exhaust is really all I added before the hypermax.
