I was wondering if anybody has tried driving with the muffler removed. And how it performs, sounds and mpg. My friend removed his off his frontier and he got better performance and mpg without much increase in sound. Thanks.

removing your muffler will make your truck too loud. I am not sure what the laws are like where you live, but it is illegal here. I do not suggest it.

I this from experience? Have you actually done it? I have heard that on some vehicles do not get excessivly loud with the stock muffler removed. However, I did not start up my truck or drive it when I replaced the stock muffler. I would just get the magnaflow and swap mufflers. That is what I did. There are sound clips of all three sizes on here somewhere. I did the 18" and am very happy with it. It was only $60 shipped. Thats less than a tank of gas on these trucks.

I think RB's removed his during a S/C install and had significant gains with that setup. But later returned to a muffler setup. Power is there, along with a bit more noise. A guy on my street has a late model Z28 modded up and he is running straight pipes. Cant really tell until he gets on it some. I wouldnt run striaght pipes on a daily driver becuase of the sheer noise. Heck my system is loud enough as is!!!!

My co-worker has his 05 F-150 straight piped and while it does sound like a nascar the drone from 30mph on up is rediculous.

It might sound like one but it has the power of a nascar go cart lol

No doubt! I give him crap every day about it.

Just sucks that his bike is faster than mine. CBR 1000RR vs. Gix 600

The simple fact of him running straight pipes on a F-150 automatically makes you cooler even though his bike is faster. :smokingco

I took my muffler off and welded a straight pipe with a turndown on and it was pretty loud. It sounded good until I got it up past like 3000 rpm then it sounded horrible. I did feel some low end power loss and lose about .5 mile per gallon though.
