are there any real benefits to adding a mid pipe to an intake system? does it improve/make louder the sound of the intake or does it increase the efficiency at all? or is the only real benfit asthetics?

 

just makes the intake louder... oh and it adds a few peak hp.. but you loose midrange..

 

in anyones opinion is it worth installing?

 

Dont do it. The stock resonator is very well made. it smooths out the RPM curve and is just better.

 

yeah thats what i have heard, i just wanted to added sound truthfully, other ways to achieve this?

 

if you're installing a mid pipe just because of sound.. then you my fellow org memeber are a ricer..

 

Lol^^.....well from experiance I installed my intake with the stock resonator initially and was very pleased,and power was still very smooth,tried it for the past few weeks with the midpipe and while its a whole lot louder I didnt notice any benefit from it but did feel what seems like less midrange smoothness. I dont have dynos nor have i seen any but from my butt dyno it seems "less smooth". End result for me...Im putting the resonator back on./

 

Ok. major newbie question and Im gritting my teeth just asking this but here goes; Can somebody explain this "mid pipe" on an intake? I know what an intake is, I have an Injen that my car came with. Its the filter then the tube that runs up to the TB. Is that tube the mid pipe? How does that affect mid range power?

 

It's a pipe that replaces that box shaped section behind the MAF.

 

i hate to ask a stupid question, but i have a pr style cai, and was wanting to put my stock midpipe back on and can't figure it out. The holes dont match up for the resinator to the back of the maf. What size coupling would i need? I'm thinking some sort of reducer.

 

The car sounds loud enough with just a cone filter attached to the MAF sensor. It's been dyno proven that the stock midpipe is better in the low end power range.

 

just install the lower CAI intake part to your stock stuff and be good with it.

 

When i took everything out to instal the cai, i think i might have lost a coupler. Because the resinator will not bolt back up to the maf!! dunno

i have a 3rd gen VG30E, and I have been experimenting with that a little this past week or so. I put on a cone filter, and it was good and responsive and smooth, and had a nice purr. I cut my resonator off of my midpipe, plugged the hole, and now I think it was a mistake. It's actually, in my opinion, quieter than having the resonator there on my car, sounds worse, and has no effect on performance. So as soon as i get my hands on another stock midpipe, I'm going to be using that again.

i have neither a midpipe aftermarket or the stock my MAF is right on the TB

whats peoples opineon on this?

 

That really sucks, you have the shortest intake of all of us! I would try to get a stock midpipe or maybe just buy one off eBay. And where did the 3 vacuum hoses go?

 

I'm surprised your MAF has been shaken to bits by now, they are quite sensitive to harsh vibrations. The accordion section is there for a reason. I accidentally dropped my intake assembly a few years ago and killed the MAF.

 

I've already dyno'd this on my A33B. Check the dyno forum.

The MAF sees a tremendous amount of airflow, so, indirectly, timing is retared. My AFR went up a touch (leaner) when I did that. And of course, @ idle, the AFR was very lean due to the PCV breather not being attatched. The MAF 'saw' peak airflow @ 6700 RPM, but peak whp was @ 5900. It did gain ~ 9whp from 6300 - 7000.

Keep in mind, this is using A33B software.

 

just curious, for us 00vi guys, is there a way to use the stock midpipe cleanly? b/c i have an aftermarket midpipe on right now, but the only way i got the stock midpipe to work was using 2 accordian sections and it didn't even fit very well (it was S shaped, b/c the large stock midpipe box hits the ABS stuff).

 

hmmmm maybe the a33 ecu reacts very different because my timing always stays up there.

and the4 time in sig was run with maf like that . so if that hurts my power than my car must be faster than that and also my car doesnt go over the stock 95 max redline . and if its helping i may not see all the benefits that way

 

I stated it in theoretical terms, as I don't have any data to prove it. Nonetheless, it will be a small amount. Also, it ahs been proven that the A32 MAF/timing reacts the same way when going in the other direction (taking fuel away = + timing)

Also, I never said it hurt power, take a look in the dyno section, I gained area under the curve throughout.

 

So how many people are using the stock midpipe along with the Cai going through the fender. I'm thinking about doing this. Just looks kinda funny though

 

Some people are doing this and claim that this is the best setup.

 

Since the stock stuff doesn't sit right with the 00vi and the block/pf tb I'm using, I'm having piping made to use the stock midpipe with. Figured it would be solid, paint-able, fewer plastic/rubber connectors and should fit perfect.

 

I've tried many different ways and IMO this is the best way. All the other ways are very one-sided in the power range but this way gives more top end and is also really smooth on the bottom-mid range. I'm not worried about how it looks. Plus you still get the sound of a CAI.
