Went to TJ Today and had the time to record a small clip of the MDX hitting VTAK! in a Tunnel!
It was 2x 2nd gear Pulls so you can hear the VTEC Crossover in all of its mighty glory... Enjoy:

I'm sorry man. That was a terrible sound clip. I couldn't hear anything.
Side-but related-note: I test drove a 2007 mdx elite today and I loved the vtec change over. It was amazing. It is going to be hard keeping it out of vtec with that intoxicating sound. I can't imagine how amazing it must sound with an exhaust.

I watched it an hour or so ago, just too much wind noise, but a good attempt none the less...
I liked it for effort...
Maybe it's just our, or at least my, iPhone (Smart Phone) speakers are too weak...
Funny note.. That was the best recording out of 3 smartphones
I didn´t take the Gopro with me this time since it was a flash trip to Tj, the worst smartphone had a popcorn sound in the recording and the 2nd best had a echoing that reverb all the sound.. Smartphones + Wind Noise = No Go... But I was there so better something than nothing.
About the exhaust... I was thinking of doing some straight pipes in the garage just for kicks but the mufflers have hard pipes into the resonator which makes them very hard to do without a mandrel bent which I don´t have. The easy way will be removing the resonators with straight pipes but that will introduce horrible drone...

It's all good man. I just thought maybe it was on my end and not on yours. But midnight confirmed that it was not just me haha. But please do share more! But with a go pro next time maybe?
Oh my god I would love you if you did that. I have been dying to hear a straight piped 2G, I of course would not EVER consider it for myself. Can't imagine the drone and the obnoxiousness! But vtec takeover would be amazing. The 3.7l really has this deep V8 tone (I took my father with me today to see the MDX and he asked if it was a V8) and it is dying for some mild exhaust work. Maybe cut off a resonator and then j-pipe.
Interestingly enough the 3G mdx's engine note is much more intrusive. So much so that my friend mentioned it when I took him with me on a small highway jaunt in the loaner. Let's just say I put that 3.5l "earth dreams" to work. I'd like to see it try and have earth dreams with the reaming I gave it. But I don't mean in a bad way, I mean in an "omg this thing is LOUD" way. It was pleasantly surprising. I like hearing my engine, especially when it has a pleaant note like the 3G does.
Yeah the exhaust on the 2G is the classic Acura Style which just comes alive with High RPM but dead silent in the Low End which is a shame.. Although I would not like intrusive engine noise inside the cabin all day long like my TL-S that is home made straight piped (Clip:
).. With only the exhaust delete It will sound amazing on the MDX, leaving the Resonators will take care of the drone. I wish I had a mandrel bent to do the MDX but I don't want to do a half-ass job If I decided to keep it that way.
That is all hard tubed (Welded) from the right exhaust all the way to the resonator and cat.. WHAT THE FREAKING HELL ACURA???? DAMN what will happen if somebody bent its exhaust tip that is also welded? Replace all that thing??

the CL
My MDX is a 2007 TECH + RES.
That is my thing too. I don't want constant sound, it gets incredibly obnoxious and sometimes I do want a smooth calm ride. Ideally I wish it would come alive at 3000 rpm and not 4000 but its ok. I also wish more noise would make it into the cabin and that it had a deeper growl.
Just so I am not confused, exhaust delete removes the 2 resonator looking things just before the exhaust tip correct? So like a catback exhaust? Does the 2G have multiple resonators, would removing just one be alright?
after j pipe and hfpc change exhaust sounds just right.... No drone, just sounds more aggressive...
I was hoping you would chime in! I seen your MDX 0-60 videos on youtube with the j-pipe I beleive. I love how the mdx sounds in those videos, I also approve of 6.03 0-60!
I´m pretty sure it can pass it, but being a non-CARB part my local facilities will not allow me to run the test anyway... I will need to find a friendly ($$) facility that allow me to run the test without checking for CARB Parts..
In any case, 600 bucks is still a boat load of money and I have yet to see lack of power in the corners.. Unless I give 2 rats about Drag Racing the MDX, Modding isn't on my priority list, I'm pretty happy with the MDX Performance since I'm not drag racing it.

I understand. But for me the extra performance is a welcomed side effect, the improved exhaust sound is definitely my main reason. I think the J37 has awesome sound potential.

Well that is the biggest Honda engine that I know of...
I know I this isn't the popular choice around here, but I love aftermarket intakes...
The J-Series V6's beg for an intake, it makes it purr more, and Vtec becomes more noticeable, and it only makes noise when throttling hard...
Now if only someone supported the MDX as there is nothing at all but homemade intakes, but I bet a 3.7 TL intake will work with little to no mods... Honestly, I've read in Honda forums the V6's really benefit from them, even if it is just 7-12hp it helps with throttle response and revs quicker!!!
For me I haven't touched an exhaust system in my life, so I can't speak much for a J-pipe, if it works like I hear it does on 3G TL's, great!!!
The Stupid MAF Sensor is the only issue, Makes building a custom Intake somewhat challenging.
In the TL-S side we have the "Resonator Delete" Mod which basically allows that sound to be noticeable over the OEM Intake Box, Its not as awesome as a proper CAI but since we got no options in the MDX?
Someone knows if the MDX has an Intake Resonator Box? I haven´t looked into that.

That is an excellent alternative if the 3.7 TL or ZDX intake is incompatible... (If one is even available)
Honesly, it will be cheaper, and with a K&N drop-in panal high-flow filter, it should be quite nice sounding...
I found it shocking when the MDX didn't have an intake on the market... My RDX has three available, and just about every other vehicle out there...
I feel bad for those MDX drivers as all they can really do is exhaust work!!!
I was lucky in my old vehicle, I just added a cone filter to where the airbox was attached, no problems!!! Took 15-20 minutes, costed about $40 after buying the filter lubricant oil...

Actually you will lose power with aftermarket intake, it was proven with dyno runs. The only aftermarket intake on j37 engine know to get some power gain is CT ice box.
stock intake is design pretty good ant it is not bottle neck for sure. Talked to the rv6 who tuned my mdx and he said it is pain in the ass to tune the car with an intake.... and there was no gains...
If you want better sound from your intake and lose some power from your engine, aftermarket intake is your pick

It's hit or miss really...
My Kia (2.0 N/A I4) had good gains in the fall, winter, and spring months, summer and tot months were a crapshoot however...
But my Toyota (2.2 I4) hurt it bad, really bad, but the engine was already on the way out...
It depends really... I've heard of V6 Accords running much better times with an intake... 0-60 in 6.5-7.0 to about 5.9!!!
With an intake and 93 octane, I had my 12.5 second Kia running high 9's!!!
Also, it works on the RDX, like mine... Honestly, it just depends, but I like the sound...
It all depends on the TB size and entire Manifold capacity.. You can use the biggest intake ever that if enough air cant cross the TB is useless... On our TL-S side the Intake and I mean the MEANEST and most Expensive CAI can only make around 4-7HP tops, That is because the TB is the biggest restriction not the Air Intake tube.
The MDX AFAIK has a bigger TB to accommodate the extra air flow, and by the looks of it the Intake is the least of the problems...
A Manifold plenum extenders like the P2R Plenums will be far more useful:
but since the J37 use a single piece Plenum we are all screwed....
The MDX is not aftermarket friendly at all and the only mods out there are SERIOUSLY not worth the Dollar per HP.

From what I understand. The J37 is a very high strung engine, as in they really had to work hard to get it to the power numbers at the time. When you look at the competition back in 2007, this engine was really ahead of the curve.
Therefore Most (not all) changes will have negative effects, not positive ones. The J-pipe mod makes sense because the factory one is surprisingly constricted. The factory intake is not really bad at all, I have seen pics. It is pretty wide actually.
In my ideal situation Honda would have maintained their V8 plans and not scrap them during the 2008 recession. We would have a V8 mdx, say 4.2l. That would have been sick! But I digress.

I never knew Honda was even considering a V8 ever...
I'm a bit mad that Honda dropped the J37, and went back to a J35... I know the new MDX is faster, but the J37 is just a big engine that likes to purr... Besides, 300-305 HP out of a 3.7 in 2006 is really good...
Once again, intake is simply for sound...
In this case, I guess a resonator delete and a J-pipe if the intake isn't so good...
Look at the damage the 3.7 did in the TL... 0-60 in as little as 5.1... Now let's make an MDX that fast... That would be fun, haha!!!
If comptech could get its shit together... we could have a SuperCharger for the MDX....
Right!! Like come on please! The MdX would be SO BAD ASS.

The RL and NSX were intended to have V8's, but when the economy crashed Honda scrapped its' plans for a V8. I wonder what a Honda V8 would have sounded like, what kind of performance it would have had.
I always loved the J37, but the new J35 is a completely improved engined in many many ways. Also the J35 sounds pretty damn good. So I think it may be the right idea. But I think they should bump it to 300hp, because let's face it 300hp sounds better than 290.
I might do a J-pipe and then change out the exhaust tips for straight pipes. A.k.a axle back.

A Honda V8, I know it would sound good...
The Ridgeline could have used this along with RWD... That thing must have a ton load of understeer with 80% of the weight over the front axles, at atleast it seems...
To me, it's kind of regressive to go from a bigger to smaller engine pushing less HP, even if it's just a little...
Maybe Acura should bring back the J37, refine it more, improve it and rate it at 340hp, if they can, and pair it to SH-AWD MDXs, and leave the J35 in the base only... That seems fairest to me...
Maybe when the new MDX comes out in 2020, which keeps up with the six year module run, with a mid-cycle refresh (MMC) at the third year run, and change it up there...
The exhaust should sound great as the engine has large displacement and many cylinders... Like the J30, it should sound great with exhaust mods... Some claim modded (exhaust) J series engines end up sounding deep and throaty, like an Infiniti G35/37 exhaust note!!!
So is there an big intake resonator on my 08 MDX to remove like on both my TLs?
A mid muffler delete? or other easy cheap exhaust mods?
The MDX is mainly my wife's ride, so I haven't spent all that much time looking into things, but the other day I took it for a "spirited ride".
For something so heavy, I thought the acceleration was great for what is basically a medium sized truck, it really roars when the Vtec switches over, makes me wish it was a little louder, and I love hearing the intake on the Honda J engines.
The high speed handling on curves was surprising good.
Especially when you can power through/out of the curve and the SH-AWD pumps that extra torque to the outside rear wheel & brings the rear right around nicely through the curve. It feels heavy in the curves, but didn't feel top heavy like I expected.
Would love to hear the difference in Vtec between yours and a 10+ with dual Vtec
I heard they changed some things with the 2010+ engines. Wasn't aware that they added dual Vtec! If you go on youtube and search mdx 0-60, there is a video posted by a member on this thread (dizionassi? Spelled wrong I know). You can hear the vtec awesomely on a 2010+ mdx. I beleive his is a 2011.
