Uncork your diesel!
Allow your diesel truck to reach its true power potential with our Summit aluminized steel "turbo-back" exhaust systems. Featuring large diameter tubing, they reduce power-robbing restriction and unleash more horsepower. The systems include a 4 in. down pipe for enhanced pulling power at highway speeds, and use an actual diesel muffler (not a modified gas engine muffler) to resist clogging. Installation hardware is included.

Exhaust System, Rapid Flow, Turbo-Back, 4 in., Aluminized Steel, Ford, Diesel, Kit


Reduce temperatures, increase horsepower.
Bully Dog's Rapid Flow exhaust systems are a great way to reduce your diesel's exhaust temperatures while increasing horsepower and economy. These systems boast the lowest-degree mandrel bends around, thereby promoting a free flow, resulting in more horsepower and torque. In towing situations, these low-backpressure exhausts lower temperatures by as much as 200 degrees, and provide a 10-20 HP gain, depending on the size of the upgrade and the current horsepower output.

i dont think there is much difference. first off, i dont think Summit knows their way around a diesel engine, i wouldn't buy from them. i think bullydog is WAY overpriced on that.

i would guess fitment issues on those two systems. if you are sure you want a 4" and not a 5" system, check out Mark Romriell. he sells 4" systems too, Uber cheap.

check out this auction. http://cgi.ebay.com/ebaymotors/4-INC...spagenameZWD1V


no muffler!!!

 

Also, you may want to check out the 4" MBRP from DieselSite. I would also suggest adding the exhaust delete pipe, from my experience. I'm not a BD expert, and happen to have a family member that sells it. But I can't imagine what they could do to an exhaust system to make it cost that much.

 

I bought a 4 inch from a guy on Ebay not sure if this is the same guy but the link in one of the posts above me looks very similar in price and all, I can say almost 2 years on it and not a problem at all. the power increase was not as much till I got the super chips tuner and the exhaust definatly made a difference here. The plus is the sound it sounds just great.

 

What are the pros of going to a 5 inch exhaust? Is it overkill on a basically stock motor? Im assuming the price is more because of the muffler........ Does anyone sell it without a muffler? trying to save a buck or two
Thanks, They have pretty nice setups. I like the stainless :drool:

 

5" is even overkill for modified truck. it is all about overkill.. do you want to make a statement with a 5" sewer pipe under your truck, or do you want to go with 4"? you said that you wanted to save money, so i would go with that auction i posted to you. 4" and muffler delete. once you hear it without a muffler you won't run a muffler, ever.

 

Also, I haven't actually seen it to compare, but I've been told that after about a year the aluminized and SS will look pretty much the same.

 

Would the 5 inch do more harm than good? I know with the Mustang if I were to run 3 inch, Id probably lose power. Is it the same with the diesel, Or not? If its only a looks thing, I might want to think of 5 inch.

 

From personal experience there isn't any power lose except for maybe below 1000rpms but unless you have a standard I wouldn't worry any about that. However, not to sway your vote or anything but when you floor it and here that straight piped 5in roar up past 3000rpms you will be glad you spent the extra 75 bucks even if it is just overkill.

 

Yeah? How about after 3 years if you ever venture into anywhere where salt is used on the roads, or is in the atmosphere such as along the Gulf Coast or Florida? I never even considered the aluminized even though I do my best to avoid the above conditions and there is a good chance I am the poorest member of this forum.

 

I would think unless you consistently polish the SS exhaust, it would start to corrode as well.

 

Black88GT,

The 1st thing you need to consider is the sound and muffler designs, both of these systms use a hollow core muffler (saves a lot of costs) and it sounds "odd" to lots of folks, plus it actually creates a restriction in the system and the exhaust gasses are bouncing around inside the muffler looking for a way out. I would suggest you look at the MBRP or AFE systems, real mufflers that are packed with high temp ceramic blanket and the price will be between the two you mentioned in your post.

Aluminized is fine for those in the dryer climates of the US, 409 stainless will tarnish and get spots on it but will last and last. It's what the OEM's use for stock exhaust systems and they have to warranty it from the cat forward for 100,000 for the Federal emmissions laws too so you should ge a long life out of it. If you want the best get the 304 stainless, stays shiny and bright and coems with dual wall tip(s) as standard equipment.

4 vs 5 inch, 5 inch isn't necessary till you get to 500 RWHP, even then the benefit is minimal. Lots of folks like the looks and louder sound the 5 inch has, we sell lots of it because of that as well. Of course you can get oen of our 4 ro 6 inch tips to get the "look" of a 5 incher too if you want.

If you have any questions on them let us know.

I went with the MBRP 409 SS Duals. I love it. There is no done at all.

 

Very good information, Thank you. How much more noise would a 5 inch make over a 4 inch setup? Should I run a muffler? Most ppl say no muffler is best :shrug: Anyone know where I could listen to a few clips online of both sizes, with and without muffers? Again, Thanks everyone for the input!

 

here is a page of Kwikkordead's signature. these clips are effing amazing. mine sounds a little deeper than that, but you get the point. his exits in front of the rear tire, and i believe he runs NO muffler?
