2.5" mandrel bent stainless steel exhaust on an L300

[Tojo]

Hello everyone,

I just got the exhaust on my L300 replaced by Muffler Tech in Port Coquitlam, and I thought I would share my experience.

http://www.muffler-tech.com/

I wanted to get a complete end to end stainless steel exhaust system installed without reusing any of the old exhaust system. Ryan, the owner gave me a few options, and we ended up going with a Flo-pro 18" oval muffler, two sections of mandrel bent 2.5" tubing (not cobbled together with multiple pieces), and a waterjet cut custom flange. I chose a 'squarish' tip that I thought would go with the boxy look of the van. The challenge was to get past my spare tire and trailer hitch without touching or rattling against anything (like the previous pipe did) and exit in the same spot as the stock pipe. I had looked into the side-shooting option, but with kids I needed a quieter pipe.

Apparently Ryan says that there is some variation when it comes to the exhaust manifold bolt spacing on the L300's depending on the year. If you have the same spacing as mine, you can fit a 2.5". If you don't, then you fit a 2.25" tapered pipe to the flange and then open up to 2.5" like Fexlboi did here: http://www.delica.ca/forum/another-exha ... -7985.html

I've included a picture of my STOCK flange. It has a bolt spacing of 92 mm and an I.D of 2.476" (62.89 mm).

All in all it was a good experience. I got to check out the mandrel bender, drive the courtesy truck for the day, and pick up my Deli the next morning. How much you ask? Pretty much what I expected for top notch work. PM me if you want to know. More than an aluminized muffler and less than the cost of my laptop! BTW I am not affiliated with this shop in any way!

Surprisingly it is a fairly quiet pipe. Very close to the volume of the stock pipe, but at a different pitch. It has a deeper rumble when you punch it up a steep hill and engage the turbo. The engine feels more responsive, and there is the perception that there is more power, especially rolling on from 70 to 90 kms/hr. As I understand it, the free flowing exhaust allows the turbo to spool up faster, and without back pressure the diesels can 'breathe' and EGT's go down. Maybe one of the experts on the forum knows more on this.

Cheers,
Tojo

Good call on the square tail pipe.

I kinda want to know how much.

Thanks, Togo.

Something to think about - stock muffler $850 or this beauty for $1350?! Hard not to think about what I could spend $500 bucks on?

Yeah, I hear ya...

2" lift kit, custom bullbars with winch, set of Hella lights, new wheels, snorkel,
and I want one of these one day: http://store.vurv.ca/delica-l300-console/
and, and, and, the list goes on. So many mods to do...

Getting the 4D56T to breathe better, well, I guess it was worth it to me for the long term health of this little overworked motor, the EGT's decreased a bit, turbo spools nice...

Really nice job. I did this on both my L300 and L400 but I chose to side-fire because I wanted to conserve space for rear-mounted fuel tanks. I also chose a 4" Coretek resonator, which is more expensive but superior to Magnaflow. I opted for 2-1/4" pipe because it fit better, and I didn't bother with the pretty end on the tailpipe (square end is sexy!). In both cases the total cost was under $600 tax in.

I'd like to bring back this thread because this is something that I want to do to my new(ish) L300, stock height.
I can't decide between the full length or side exit. I like the idea of full length, but I like the option for extra or WVO tank. And the price...

I'd like to ask those of you with a side dump, what do you NOT like about it?

Cheers

There's nothing I don't like about it. That said, or is noisier because the sound gets bounced back at you off meridians and I occasionally smoke our people on sidewalks. the pro is less bends to restrict airflow, extra space under the van and you can check while driving to see if you're blowing out smoke.

EDIT: technically they are illegal as well.

As no one seems to make Mandrel Bent in Quebec City, can a Delica ownwer in a need for a new muffler get in touch with me before going to Muffler Tech: I would ask you to duplicate the Flange AND the first Mandrel Pipe Tubing that will be soldered to it (Picture DSC08948 above). Of course, will pay my parts and shopping overhere !
