Need a muffler delete pipe

I want to remove my muffler from my stock exhaust on my 2003 F350 drw and need to know who sells the replacement pipe? I could not find any muffler shop around here that has 3.5" pipe or that can bend it.

I don't think anyone sells a straight pipe replacement. You'll probably have to get some elbow adaptors to make it work. Go to http://airflo.com/index.html to see what they have. If you have any big rig truck dealers or shops in your area, they should be able to supply you with what you need too.

Why is that better than a BTM?
What advantages and disadvantages? I think the BTM is cheaper.
Not knocking what hotwheelbill wants, but info.

It's not necessarily better. They are both allow the exhaust to flow straight through.

The difference comes down to sound. The straight pipe will give a lot more sound than any muffler. Plus, the straight pipe will give a lot more drone than a muffler. Not a big deal if you don't do much highway driving, but if you're on the highway, it can get pretty tiring. I took my straight pipe off and a muffler back on (the one that came with my exhaust system) to get rid of some of the drone.

All you need is a piece of 3.5" straight pipe... it doesn't need to be bent.

Take a look at this picture:
http://community.webshots.com/photo/...55918709HZIAgb

it belongs to twistedtj from TDS.... notice how the S-pipe part was rotated up 180 degrees to make the difference in height between it and the tailpipe pretty negligible. Then on the straight pipe, the muffler shop will just flare the ends a tad and then weld it on. Any shop should be able to do it as long as they have a piece of 3.5" straight pipe, of you can pick one up at a big rig shop and bring it in. They charged me $60 to cut off the muffler and install the straight pipe... others will be cheaper. The BTM will be $50 or so on it's own, plus another $50-60 to cut off muffler and install, so it will cost more. If you want some sick sound I'd go with the muffler delete over the BTM... I don't notice any difference in sound with the windows up, even on the highway, but maybe I'm not trying hard enough. I tend to drive around with my passenger side windows down now, anyway, just to hear the exhaust.

My C/Cab has a delete pipe on it. I can't hear any drone at all on the highway. I just drove it on a 10 hour roadtrip yesterday too! Only time I can hear it is when driving next to a car or a highway's sound barrier, etc... But then it's just the sound you hear and not a drone.

My truck's interior noise is no different than my dad's bone stock C/Cab. I did notice that my delete pipe's ID is actually larger than the exhaust's OD, plus it's a pretty heavy wall pipe too. Maybe this has something to do with mine not having a drone???

I have also been very curious about the posts indicating problems of drone. With the stock exhaust and BTM, I never had the problem on my extended, 8ft bed PSD. I was concerned when ordering the 4" MBRP system of running into this, but after installing it, no drone again. It must have something to do with the overall length of the exhaust, exhaust frequency and resonance frequency of the exhaust system itself.....

Most often a "drone" can be traced to the exhaust system contacting the truck. Generally the downpipe will touch the frame or body at the transition under the truck, but it can be anywhere. I initially had a droning problem with my dual exhaust until I found the spot where one of the tailpipes was contacting the heat shield on the underside of the bed.

There is also the issue of perception. What some people think sounds good may be an annoying drone to the next guy.

What I was going for here was to lower my EGT's without blowing my warranty on the motor. My gauges will come in on Wedsday and I will install them to get some temp readings before I cut out the muffler so that I can compare the EGT's some. A drone would be a problem, but a change in sound, loud, pitch, ect. would not be a problem. The $85.00 replacement pipe seems a little high, I will try one of the big truck dealers or shops in Jacksonville next week sometime and post the results....drone or no drone.

Excellent point cookie! One that I had not thought of, but the exhaust will definately vibrate to a more or lesser degree at various engine RPMs.
