We need more exhaust videos

[Jake@JHM]

Haha yea, we need morez! I just talked to him. He is going to put together a quick vid of when I had the resonated system on my car.

So you're just using an adapter type dp to connect to your aftermarket jhm s4 exhausts? Or to stock s4 exhaust?

Yeah, Our 3" DP turns into a dual 2.5" Y so it will mate to either the stock S4 Cat back or 2.5" Aftermarket like the JHM/Fi systems we sell. You will have the option at checkout for the sizing.

So sexy,

[Jake@JHM]

I know right?

[Salt n Peppa]

Yeah, but your car specifically has the oem s4 cat back, correct? Or just for those passes at the strip

From what I've read it was purposeful and practical when you think about it

I believe his car has the 3" to dual 2.5" downpipe as pictured above, with an aftermarket Fast Intentions B6 S4 catback (dual single tip), also sold at JHM.

[Jake@JHM]

My car only had the OEM s4 cat back for the 91oct and 93oct 1/4 mile videos. The 100oct pass had the resonated JHM/FI 2.5" Cat back. Now I am running the non-resonated JHM/FI Cat back.

Stock B6 S4 Cat back:

Well I don't doubt that lol I was just wondering what I was listening to on the video. Can't seem to find the dp on the site though

Haven't officially released it yet. We have it installed on multiple 6MTs and even a CVT. Just waiting for a local TIP to get on board to confirm fitment on everything before we release it.

If you have a 6MT, PM and I can sell it early .

Sorry, tip here :/

Looking good

[PNW Avant]

I guess mine would sound different as I'm aiming to run a HFC rather than test pipe. Decisions decisions.

[Jake@JHM]

Eh.. Not much different.

If any of you have any questions about the DP/TP with an OEM b6 s4 catback, you can PM me or see my thread :D

^^ First hand experience right there!

psh just run open turbo, after the turbine, just have one pipe that dumps right out the front passenger tire.

Fixed.

[Jake@JHM]

Haha, that would be so loud. I drove around with open DP for a day and man, that was LOUD.

meh... 4 cyls are quiet, I remember this guy with a b6 s4 and the fast intensions exhaust, that guy was dangerous in a tunnel!

Hahaha yeah these systems are pretty sweet. I love the way that they sound.

[mec]

I tried to do a tunnel pull and sound cool, but it turns out that 4 cyl's have no growl...instead you could just faintly hear a turbo. I really have to have load to get decent noise out of this engine.

[Jake@JHM]

Yeah the V8s have a much better sound as compared to the 4cyls.

Martin, what are you running for a hot air intake. Stock box really muffles all the turbo sound. I did a tunnel pull on the way home today and get a nice turbo spool pssss and definitive blow off psshhh on shifts. I would figure with your GTx the spool would appreciable...

3" silicon intake bend to a 3" cone filter. you can hear the turbo spool from like 2000 rpms and up, but even with a free flow exhaust it isnt as throaty as a v8

mine is just a coupler and a filter and i don't have much turbo sound esp in a tunnel but maybe that's because my exhaust is pretty loud. i do hear my diverter valve pretty well though

[AUDIA8MAN]

subscribe:)
got a a4 b7 sline for DD and lapping,got a few things on it to make more stable and a little faster,but there seems to be missing something like.... 100hp:)
I got the apr stage 2 with a rai downpipe,which is fun don't get me wrong, but on track I catch up in the curves bmw 135 but not on the straights:( by not much though...
keep us posted for the stage 3+++
might get the trio kit...

Where your maf?

[Jake@JHM]

What are you guys using for a diverter setup?

[mec]

synchronic....or synapse something like that

[Jake@JHM]

Do you guys code out the OEM DV or just leave it plugged in?

I'm going to look more into this but apparently for the EFR turbos you can use the stock DV.

Sounds plausible:






Operator has an EFR, maybe he can remove his DV and see if the OEM one fits =P

Yeah I asked Operator about putting back in the stock DV, but the last time I saw his car the DV was plugged in and pushed off to the side. A guy named Bische with B6 6758 has confirmed the stock DV fits. http://www.audizine.com/forum/showth...?highlight=efr

Hey that is pretty cool! the EFR seems like a solid upgrade for the B7 A4. Having stock like DV location and being able to use the OEM DV makes things easier.

[aluthman]

I'm using the Synapse DV. I took an old N80 valve and plugged it into the DV plug, then tucked it into the old SMIC cross pipe. It's basically acting as a resistor. I've yet to get any type of code from it.

[Firefox250]

Cough cough JHM EFR kit : )
