Well I woke up early and took the van to Sandee Muffler in Culver City. I have been going to this shop for a couple of years for exhuast related work. They are really nice people and can custom fabircate almost anything you want. I was under the impression that the MPV had a 2 inline catalytic converter setup. Once the van was on the lift we could see that there were two seperate catalytic converters which came together in a y-pipe>then to the premuffler> then to the muffler. We decided it was best to fabricate from the end of the y-pipe since it already had a flange. I chose to go with 2 1/4 inch piping to maintain some back pressure=torque. The van sounds very agressive at WOT. There is no droning while driving at a sustained speed, and no droning at idle. I am quite please with how this project turned out. Ill post pitures in the photo section shortly. Decided to put this post here since this isnt really done to increase performance. Im trying to massage more MPG out of the van. I had the factory exhuast altered and a K&N filter with my last van and saw a 4 mpg city and 7 mpg highway increase over stock. I will keep my eye on how the this has affected my MPG, since different cars yeild different results. As for the butt dyno, it feels like there is more power in the mid-range. I will have to hook up my g-tech competition pro meter to find out if this is indeed true...

I see you will make more mods to your MPV than all our members did together till this day. Wink

Post a video with sound as well if possible.

Modifying cars is a nasty habit I picked up from my father. It does not help that I have a very understading wife who generally supports my intrest in cars. Going to car parts stores, car shows, car club meetings, she is there. As for video with sound it will take a little longer to get. Any suggestions on where to host it?

I used a 5-Zigen Fireball 150 muffler. It is no longer produced. The tip of the muffler is 100mm or about 4 inches.

Well I disconnected the battery over night to reset the ECU. The van is more responsive now and actual shifts seem more intuitive. The day I had it installed I was noticing some considerable throttle lag, especially from a dead stop to WOT (Onramps for Los Angeles Freeways). Everything has smoothed out and feels much better.

Do you plan on throttle body and fuel upgrades? I do agree that car habit can sometimes be ... a little... on the expensive side. But, hey, life is good!!! We are rewarded for our hardwork by doing what we like to do while having the ability to do it. Razz

Better than spending the money on drugs and alcohols and end up with massive medical bills. Very Happy Very Happy Cool

No throttle body or fuel upgrades planned. I think exhaust, intake, and voltage stabilizer is about all I will do to my van engine wise for now. Still have the factory warranty and enterprise warranty to think about. After that runs out, who knows. Cool

Sweet! Let us know if you see mpg gains with your present set-up. Might consider doing the same. Any suggestions of products currently available that would have the same look and minimal droning? What did the install cost you there in Culver City?

I would definitely steer clear of the $50 too good to be true muffler. These mufflers tend to rust out in less than a year and or develop leaks after a relatively short amount of time. From my experince, Magnaflow mufflers sound good and they are reasonably priced. If you wanna go crazy like I did, you can buy a more expensive Japanese brand like Apexi, 5-zigen, Blitz, HKS, etc. IMHO the Magnaflow will probably suit your needs just fine. The install was bit pricey, $200. But considering this involved a lot custom fabrication that I supervised I am happy with the price. The manager of the shop personally installed my muffler. We talked over our plan of attack, They let me go underneath the car while it was on the lift. They let me position the muffler by hand the way I wanted, and watched most of the install. Im sure the muffler shops insurance company would disagree with me being in the work bays, but its one of the perks, having done business with them before.

Yes, I'll hook you up w/some space for a video, as long as it's not too huge. Just PM me when you're ready.

Mesa like Fireballs. Good choice, and the instal looks awesome.

Shane you're right. The shop's insurance agent would've been having a heart attack if they saw you under a lifted car in the shop. Smile No blood, no claim fowl though!

I checked my mileage when I had to fill up my gas today. Looks like a 3 mpg increase over what I was getting with the stock exhaust set-up. This came as a surprise to me as I have been more prone to mashing the gas pedal because I like the sound at WOT. Ill keep cheking if my milage stays at this increased level. So far so good Smile

How's the sound at idle? Any significant increase in noise making its way into the cabin when you're just cruising on the highway? How about outside?

I also like the sound of the Duratech when it's banging past 4k to the redline myself. It sounds like the engine is eager to rev...I think having an exhaust that adds to that experience will make my MPG worse Laughing
