MDX J-Pipe Interest?
I didn't even realize that we added on a MDX section. Great stuff!
Anyway, a few MDX members from the other boards have e-mailed me asking if the J-Pipe was interchangeable, since from the pictures of it, it looks like it may be a close enough fit to do away with minor modifications or none at all.
Here is a diagram of the stock MDX exhaust section.
Note the MDX (1st picture) J-Pipe (1st exhaust article from engine-back), in comparison to the TL J-Pipe (2nd picture).
Here is a picture I was sent from Chris of the factory MDX J-Pipe.
And this is our current one for the TL.

I'm curious.

Thanks for getting my pics up of the downpipe....sorry I've not been able to test fit the downpipe.....wife is due any day now with our first child....so no new projects for a few weeks for me (unless I feel lucky...punk)
I hope someone jumps on one of these.....I believe Mike that your test pipe will work with the rear/secondary cat to delete it.....from my measurements they are the same.
Thanks,
Chris

aznbo, if you have one in stock I can give buy it and see if it works on the MDX, if not, I can always put it on the TL.

After looking at both my TL and MDX, it's doen't look like a TL J (aftermarket or OEM) pipe will fit a MDX. If somone makes a J pipe specifically for the MDX, I will be the first in line to buy one. Otherwise, I am thinking about having a local guy who builds stainless steel turbo headers build a SS J pipe for my MDX.

After taking those photos and some measurements I'm pretty sure that it will fit, but let me know.....I'm back in the market now....if it does I will take one.
Also, on a performance note has anyone looked at how restrictive the 08-09 factory air box is...I put a K&N in mine and plan on doing some cutting on that box next weekend. It only pulls air thru an area about 3.5" in the middle of the box. Need to cut out the two panels inside to create more reserve volume inside the box....nice for VTEC.

I hope you're correct, but I looked under the wifey's TL and my MDX and I don't see how it could fit both. Hope the heck I am wrong, because I surely would like to have one on the MDX.

Did you notice any change with the K&N in throttle response? or anything.

Yes I will get video to.After I dyno I will pull pop off the bottom half of the air box to see how much restriction the resonator is,and make another pull.I really want this J-PIPe to FIT!

I did notice a difference....small.....with the K&N filter. When you pull the top on the air box you will see what I mean about the restriction. Its in the box....a channel that runs throught the middle to get air to the throttle body. It is only about 3.5 inches wide where as the box is about 8x10.
The cold air part of the box coming from the bumper is perfect...large and free flowing....but I am going to cut out the channels inside the box.
I think it would not really make much power but only to build throttle response.
Just my 2 cents,
Chris

I have also picked up a K&N filter so I can swap em on the dyno to see if it does anything at all.

So the dyno today was great they posted up the video and it was deleted??
We made a base line run stock....took a few times to get it with the traction control and sport shift in third gear.Then we dropped in the K&N filter and it gained 3.5 hp and 3-4 TQ all the way on a hot pass(intake manifold was hot) on the dyno pull.Pete will probably post up the dyno sheet stock and the K&N drop in run.
The J-PIPE was another story it did not fit.The hanger was hitting the driveshaft and then when that was removed,the pipe was up against the transfercase.
I am having a custom exhaust made a real duel exhaust setup and then back to the dyno.

so just with a simple drop in k&n air filter you gained those power numbers? no modifications to the stock set up? wow im pleasantly suprised! also if it was done on a hot pass does that mean those numbers are conservative?

Yes it was just a filter swap and the intake manifold was kinda hot.We did not modify anything bone stock 09 MDX made the pull,swapped the filter and it gained across the board 3+ hp 3+ torque yes to say it's conservative because we tried a few pulls to get the sportshift mode right.Pete has the graph and video but it was pulled off the site.

Dyno results with K&N drop in filter
The red color is our base run, The green is with the drop in filter.
The straight line is whp and the dotted line is wtq
This is a Dyno Dynamics Dyno, add about 15% more for a dyno jet number !

Custom MDX Exhaust
Here are some pictures Peter, his friend, and I took tonight of Peter's Acura MDX at my shop. Peter noted that he was going to add "high flow" resonators and mufflers, and that is exactly what he did. We will have more dyno testing done this weekend. Here are some pictures of this beautiful custom exhaust.Remember that the car was dyno tested with the custom downpipe and x-pipe. We will be testing the high flow resonators and mufflers.
Here is the custom downpipe that will connect with a very nice X pipe.
Top notch welds.......
True dual exhaust running into high flow resonators.
High flow resonators with heavy duty thick hangers for extra strength.
Another shot of the thick hangers used. This one to support one of the high flow mufflers.
Oval blended tips with a nice touch. 110% better looking than stock.
Like I stated above, we will have dyno results for everyone this weekend. Peter and I are excited to do some real world testing on the first full true dual exhaust!
Please do not mind some of the pictures as they came out a little blury. I can garuntee the dyno sheets will be perfect! Stay tuned as we will be making a video of this next dyno session!

I will again see what the gains are with the K&N filter and the stock filter,back to back runs.
The answer to your question is yes it can be easily done on your 1st Gen MDX.

The sound is very deep tone.At cruising 70 mph on highway it is barely noticeable.This duel exhaust sound is really nice with the magnaflow resenators and magnaflow mufflers.The dyno on Saturday will have video to so you can hear it.It is nothing like the TL's exhaust with the 2-into-1 into-2 configuration.I have installed a few on TL's.
