Hello everyone first excursion 2002, want to get more performance and better fuel economy. Wow a lot of choices. Is dual that much better? So many choices. Anyone have ideas? Want to build her up right. Thanks

 

We have lots of ideas. How big is your wallet? LOL Seriously, it has wheels. How fast can you afford to go?

Duals behind the wheel wells are a difficult install on an Excursion because of the space taken by the fuel tank. You only have a single exhaust outlet on your turbo, so it's a bit pointless anyway. You're not balancing exhaust velocity from the heads like you would on a gasser.

 

Single exhaust is more than adequate.

 

Any recommendations? 4 or 5? Seems most people are using 4.

Thanks and under $800 if possible

 

MBRP, 4" .....

 

Technically it's possible a person can get a slight (very slight) increase in fuel economy while also getting a bump in performance...technically. But for the purpose of your post and for what you're looking for, "more performance and better fuel economy" are mutually exclusive terms.

Nope.

What are you using the truck for? How much do you want to spend?

Moving this over to the 7.3L PSD forum.

Mostly road trips, pulling either 24 foot enclosed trailer or open car trailer.

 

Any brand better then another?

 

There are plenty of good brands out there. I've seen MBRP, aFe, Diamond Eye, Silverline, Magnaflow, and RBP (Rolling Big Power) thrown around consistently.

I went with a 4" MBRP single exhaust (turbo-back) T-409 stainless steel which was just over $500 IIRC. If you want duals or bump up to T-304 stainless steel your looking at another $300+ to the price.

4" is more than enough for a diesel. 5" is bigger but you won't get any real added benefit besides a really big exhaust tip behind your rear tire. All you are doing is getting the exhaust from the engine to behind the truck so you aren't smelling it. There's not as much engineering in it as which is different than for a gas engine (resonant frequencies, backpressure to scavenge the cylinder, etc.).

As for single vs. dual. Duals cost more (more pipe and a second tip, possibly a second muffler) and are pretty much a personal appearance preference for a diesel engine. For gas engines a single will usually enhance the low- to mid-range power and a TRUE dual exhaust (each side gets its own independent exhaust) will enhance top end power. Most systems are not true dual exhausts (the exhaust manifolds collect into one point and then either split out before or after the muffler). Again, that's the rule of thumb I learned for gassers.

 

I don't think a dual will fit. Ive looked before and couldn't find a company that made a dual for the X. I went with a Banks 4" monster exhaust on my X.

 

Same here. Just put the 4" MBRP T-409SS on a few weeks ago. About $550 from RiffRaff Diesel

T-409 will get a rusty looking coating but not rust through. It came with a T-304 (shiny, mirror finish) 4" to 5" tip. Sharp looking.

It didn't make sense to me to spend $$$$ more for shiny that wouldn't be see, although I did insist on the Stainless Steel, being I live in the Rust Belt, LOL.

FYI. When pricing, the Excursion version is about $50 more than the truck version.

It's a tight fit, but it did clear my fuel tank and rear shock.

I am VERY PLEASED with it. A little turbo whine and a little growl. Both are more pronounced outside or with the windows down.

If inside with windows closed, not a lot to notice- just what I wanted

Good luck on your search!

 

4" stainless Banks monster w/ power elbow (better flowing turbo outlet).

 

Great thanks think Im going with 4" MBRP single exhaust (turbo-back) T-409 stainless steel. This forum is great love all the advice.

 

$497.19 from Moddiction. anyone ever heard of them??
