Another question, I already have K&amp;N cold air intake and American Outlaw axle backs installed, should I expect a significant sound increase?

Yes these headers installed with any more free flowing exhaust will make exhaust a little louder. I have almost the same set up and they sound awesome. These headers were an awesome buy

None at all, nice performance enhancement...no audible sound increase and horsepower gain noted.

I didn't have too do any thing to mine, I'm told the newer bikes are more tolerant too small engine mods.... all I've put on mine so far is the K&n; RK cleaner, and some aftermaket slip on mufflers , and it runs great / lot better than stock..... no complaints at all, and still has that stock appearance. Hope this helps you, good luck K.L.

It's pretty short so probably be pretty loud. A turbo type muffler would probably give you a deeper tone.

i have a ram 2500 .4inch is fine.5inch will give you a deeper tone. but not necessary till you are putting down 600hp .loli kinda have both . i 1st got a 4 inch delete pipe from turbo to stock muffler . then got a 5inch dpf back . which deletes the muffler and replaces it 5inch pipe over the axle back. making it now straight pipe

It's definitely louder than stock, especially if your a heavy on the accelerator towing a trailer. I don't hear any more noise towing vs regular driving. My other dodge diesel had a 4" straight pipe and that was borderline obnoxious. This system has nice tone, the 5" pipe with the muffler I would say that it's at least -10 dB quieter than the 4" without a muffler.

Yes, Harley hasn't made any changes to the exhaust with the Rushmore upgrades. You should be fine

The hardest part of the install on my '06 Avalnache was finding a circuit that was always HOT. Other than that the install is straight forward. I can't say that it will improve the sound of your truck - I dualed my exhaiust to acomplish that, but I can tell you about improved fulel economy, I avergage close to 22 mpg hi-way and I don;t baby the pedal.

I would have to honestly say that I don't know, what I do know is that I do feel and hear the difference, I plan on changing out my exhaust later on down the line which, from what I've researched is where you would see a more sizable increase in horsepower/fuel efficiency, but I know someone with the K&N; setup who wishes he would've known about Spectre because you really can't tell the difference in quality and performance, and I'm sure you've the price difference. I would highly recommend.

It'll take 2 guys to install. As long as you have the right tools, cutters, & welders, Yes... If not I would bring the MBRP box to your local exhaust shop/guy & pY them for 2 hours of shop time to install for you. Awesome sounding exhaust. If youre putting it on a 7.3 it'll give you a great jet/turbine sound.

hey Gregory swinney if your motorized vehicle is loud in its original state then maybe it will add a bit more but if it isn't it will give it a nice sound to it. but your question is if it fits? your gonna have to make a small adjustment to it. I mean by the pipe

Makes a higher pitched noise than stock, but not much louder if at all. I can say that performance is perfect...Stock BOV was leaking at 18psi, this one was boost leak tested to 22 psi and did not leak at all. Hope this helps.

There was a performance increase and great sound. I have vance and Hines tru dual head pipes as well, race tuner and it was dynoed, also Arlen ness big sucker air cleaner kit. Beefs up the hp and torque. Best pipes going had on 3 bikes. Good luck

K&N; has more of a ram air design. So in theory, it should help you get a little more HP on the top end. But, to be sure you'll have to try and find a dyno chart.

I had gotten new B pipes as well. I'm pretty sure it won't line up with the stock exhaust.

Its basically like having ur truck straight piped.. have it on my dodge with 318 magnum and its pretty loud but sounds good

The factory setup is virtually noise free. Put the stock unit back on truck. I will probably put a good filter in the box & leave it alone. Wasted $260.
