Other than my dinky factory tires, the one thing I hate about my truck is the awful looking exhaust coming out . I hate the way they run them know. I would gladly give up that extra 1/4 of a horsepower they must have gained to have the 90* bend like the older super duties had.
I don't want a loud exhaust, and not looking for HP gains, but thinking of removing the tailpipe, and just putting a turn down behind the factory muffler. Has anyone done this? I know some of you have removed mufflers and/or resonators and ran turn downs. Any problems with exhaust fumes in the cab or droning?
I was interested in trying the muffler delete. I unclamped the entire factory section of tailpipe with the muffler. Then right behind the little resonator I had a muffler shop bend an almost 90deg piece of pipe and I turned it out in front of the rear tire. I had no fumes before or after adding the turnout. I did it this way so I could easily return my exhaust to stock without welding anything back in place.
The noise and drone got to me. The truck generally sounded good, like a V8 in older trucks. I noticed zero gains on anything, just noise.
My next thought since I kind of liked the turnout at the rear tire, I would replace the small resonator with a muffler and that would have probably done the trick.
Anytime you run a turn down the noise is going to reflect off the road and back up at the truck. I don't know how it will be with a stock muffler. I ran 4 inch through a dynomax race muffler to a turndown.... Super loud. Sounded good but deafening. As long as you get past the cab you shouldn't have a problem with fumes. It's a chance you take anytime you don't put it past the body.
I'm defiantly going to wait until after our long trip towing in early June, but thinking of running some pipe past the rear end and turning it down, would get the noise to the back of the truck. Whatever I do, I will keep the factory tailpipe so I can throw it back on if I don't like the results.
Considering all the cats, plus a resonator and a big muffler I don't think the sound will be much louder with a turn down after the muffler. You could always cut it after the tailpipe wraps over the rear axle and extend the existing pipe down more to keep heat closer to the ground.
Picked up some payload capacity today.
Was going to remove just the the tailpipe, until I saw it was welded on. It sounds really good, not as loud as I expected, but drones a little to much for my liking. I'll run some pipe behind the rearend to see if it helps. If not, I may add a small muffler then dump it behind the rear end.
The weight savings was a plus. Even with the turnout I had made, it still had too much drone for me. I really think when I do this to my new truck I will replace the small resonator with a quiet muffler. I can then leave it turned out by the tire which I kind of like.
Well you will like the muffler delete then. I don't have a sound clip as I recently re-installed my tailpipe and muffler. When deleted, it has that flowmaster/magnaflo sound. It really is pretty easy to unbolt it as pictured above and try out the sound.
Can you post a sound clip? I want to make my truck louder and don't care about the drone as I run Flowmaster exhaust on the mustang.
My phone doesn't take good sound clips, but there is a half dozen clips on YouTube. It doesn't take 5 minutes to loosen the clamp infront of the muffler and disconnect the muffler. I used my foot to kick the muffler backwards until it came loose. To pull the muffler and tailpipe out, you will have to jack the back of the truck up and let the rear end sag down. I put the jack under my drop hitch.
The drone isn't horrible, but I'm going to put everything back on for our road trip pulling the camper 600 miles in a month.
