Question for those with metal mulisha exhaust.

Victory14red · March 11, 2016

That's possible.

I will be undercoating the entire truck sometime this summer. I live in the rust belt so it's almost a must. I believe that will deaden the interior noise as well.

Do you have to cut the exhaust off? I would prefer not cutting it.

Ridersfan · March 12, 2016

If you lift the truck on a 2 post hoist with the suspension dangling, you won't have to cut it. If you try to remove the factory exhaust in 1 piece with weight on the suspension, you're going to have a tough fight.

Let me add some other thoughts on the system. Initially the lower end torque felt like it had dropped off. I did a 3 hour drive for a fishing trip this weekend and got about 14.5 mpg. That was with about 45 minutes of 85-90mph cruising on the toll road, I also use e85 exclusively.

On my return 3 hour trip back the truck felt like it had learned the new exhaust and the low end torque felt better. Maybe I just got used to it? My fuel mileage bumped up to almost 17mpg prior to hitting the toll road, when I averaged 70-75 mph. Doing 85-90 on the toll again my average went down to 16mpg.

I don't alter my driving style to increase mileage so I felt I stayed pretty consistent to and from my trip. There are no major hills in the part of Texas I was in so the driving terrain was consistent too.

I'm thinking about ordering the metal Mulisha exhaust. Does it seem like I would get pulled over just taking it easy? Also leaving for work at 5:30 in the morning I don't want to piss off the neighbors. What's your thoughts on that?

I posted a video on the first page of this thread. Check it out. To be honest on a true cold start the truck is "loud". It's more that the deep rumble of the exhaust resonates. I don't worry about waking up neighbors with it though.

If you get pulled over with this exhaust it's because a cop is looking for a reason to pull you over. Even at wide open throttle it's not as loud as most corvettes or other sports cars. Cruising it's barely noticeable and at moderate acceleration it's nothing to worry about.

Ok, thanks for the input. I'm gonna pull the trigger today. Where did you order yours from?

DirtyMarcus · March 13, 2016

I ordered it off amazon because I'm wanted it fast lol. Autoanything.com has then for normal price, no tax and free shipping. Bonus, until the end of the month Gibson is offering a $50 mail in rebate.

harley_man · March 17, 2016

Just got my exhaust in the mail today. Going to install tomorrow after work.

Victory14red · March 17, 2016

Let me know what you think of it. I still haven't ordered. Where did you order from?

harley_man · March 17, 2016

Will do, I ordered from auto anything.com. It had free shipping, tax was included in the price already. You save about 30 dollars that way, cause it looks like everyone sells it for the same price. Plus it comes with a 50 rebate.

Victory14red · March 18, 2016

Sweet I'll look into them. I was thinking about ordering from summit because I have done quite a bit of business with them. But they don't always have the best price.

harley_man · March 18, 2016

I put it on last night, there is a drone in V4 mode, but feel it's not to bad. I think it's some what loud and sounds good. If you take it easy it won't be attract to much attention. If you get on it I think it's fairly loud. I'll try to get a video up this weekend.
