agreed, I have the magnaflow four inch, SS turbo back system......went on easy, was resonably priced and is only a slight bit louder than stock......and I can't tell an diff in sound in the cab.....my vote is for the Magnaflow...
I really, really like my MBRP SS 4" and am real glad I did not use the muffler that came with it. I am constantly asked by other PSD owners why my truck sounds so good without being loud. I am around so many different owners because I'm in and out of various RV parks a lot.
^ Me too, the mbrp duels turns alot of heads when you get on it, sounds great at idle too. I had numerous people ask me what kind of exhaust was under there.
Why are you wanting to keep the stock exhaust? Just for sound? I have a Magnaflow system and I cant hear it inside the truck. I think it owuld be wise to spend the 300 - 400 on one just to be safe. I would definately think that the 80 econ. tune would get hot without an aftermarket exhaust.
Basically YES...sound is the reason. I am most concerned about sound. I am not opposed to making this mod a reality, but just looking out for what the aftermath would be. I totally agree that EGT's need to be let out as i am quite interested in the 80 Econ on the DP Tuner as well.
I have seen quite a few of the units that everyone is referencing on ebay as I have been browsing/researching.....
Towing in stock would work with the stock exhaust. If you are towing around 6000# you could probobly get away with a tune and stock exhaust.
The aftermarket exhausts are not loud incase that is what you are worried about. I would do the exhaust just to free up air flow and increase performance and then you don't have to worry as much on the EGTs.
