4" Exhaust installed!

[ianjadkins]

Found a reg cab f350 at the wrecker with a 4" DP back Exhaust with a nice Tip. Picked that up and got a Magnaflow muffler from a friend. WOW! Sounds great, and picked up 3psi of boost. Went from 16 at WOT to 19. Hope to find a DP soon.

pics??? ive got 3"DP and 4" straight pipe with 5" tip and mine sounds great when you get on it. mine was mbrp, what brand is yours

[ianjadkins]

I am not sure on the brand of the tailpipe or straight pipe. I think a muffler shop just used a straight 4" piece and added a pre-bent tailpipe and welded a Chrome rolled edge tip on it. I just added a Magnaflow muffler to complete it.

What did the magnaflow muff run you? Also, did you keep your cat around or did you run it off?

I am researching exhaust. I want to go with 4" straight but state inspection will force me to keep the cat on. I called a local shop and they wanted $100 to install any system I buy - sound reasonable?

A friend of mine had the Magnaflow muffler, I paid $83.00 Canadian. I got rid of the cat. I like the sound of a muffler in the diesels. Especially the v8's. I don't like that high rpm wrapping sound. I like the low sound from the muffler so I am loving it. Now my truck is missing badly so I have to fix that before I can really enjoy it.

I like the low deep sound too. Did you notice any power difference or mostly sound? How much of a difference can you hear inside the cab?

[ianjadkins]

I didn't notice much of a power difference. I think when I add a Downpipe that I may notice a slight increase but minimal. The exhaust is more of a supporting mod for chips/injectors/etc. In the cab there is a bit of a drone around 1400-2000 rpm. but I love the sound.

I have a 3' dp, and Magnaflow 4" dp back, without cat, and with muffler, and i love the sound, and definately notice the tone. I love it

I recieved my exhaust in the mail last thursday. I got it from Tymar - it is a 4" with a muffler and a 5" tip. The tip looks nice, rolled edges and is 12" in length - but 5" looks very large lying there on the table. I am nervous to see what it is going to look like on the truck. I had a great experience with Dale at Tymar - great CS, fast shipping, and best price!

Also, I guess I have never looked inside of a muffler off of one of our 7.3's but it sure looks like straight pipe to me. I can't wait to get it installed. I plan on doing it myself but if too much time passes before I can get to it I may have to pay somone to put it on for me - just because I can't wait any longer, it is killing me having it all there in the middle of my floor.

It has been snowing here so I put the entire system together inside right in the middle of the living room floor - my wife is ready to kill me. LMFAO

Don't worry about the tip looking too big, once you get it on you'll want bigger. Here is mine, 3" DP, 4" straight piped with 5" afe tip
