Yes contact jhm about there catless dps…that will be the best bet
Ask and you shall receive. I was looking for brake pad wear sensors for someone’s car but then I saw these: http://jhmotorsports.com/shop/catalog/exhaust-test-pipes-stainless-steel-25-jhm-for-b8-s5-42l-fsi-32v-p-1789.html
They are beautiful!
“product not found” either that’s one hell of an edit by JHM, or the linky no work.
The link works for me on both my phone and computer.
My bad, it had my last search setting recalled (products vaild for a B6/7 S4). Cleared that and it pulled up.
Pretty good price actually for those pipes since no one else offers em, obviously great quality, and recessed O2 bungs for catless.
Thanks for clarifying Jbones! I see why my AWE downpipes are really not downpipes now. Although when I ordered them I opted for the non-res for less restriction?
A few months ago Jake actually contacted me about the test pipes seeing if I wanted in on the first batch! We spoke about emissions and that I would likely not pass them once I swapped them in. That is why I didn’t grab them then. I suppose if these are an easy swap without have to drop the engine or trans I could just juggle them when emission time comes around.
They are… and expensive for hollow pipes, but one must pay to play. Also since JHM are first to market they can skim
Most of the time the resonators are just for sound and by sound I mean drone.
The B6/7 S4 downpipes are $1,200 for probably twice as much or more tubing, plus flex joints, and hardware/gasket for the middle connecting flanges. But with the midpipes the B8s are probably paying more in the end.
I hate that fucking drone! I throw it in neutral or keep it above 3k rpms otherwise its a disaster
I’d say they’re pretty well priced. Having the O2 sensor recessed saves you another $50-$100 bucks form buying O2 spacers. And you’ve got madrel bends in 2.5" piping with some fairly complex bends (well more so precise bends since you don’t have flex pipes).
The first DP’s that came to the B6/7 market were twice that if I recall. As time goes on, someone will copy them with slightly less quality and offer for a coup0le hundred bucks less.
But either way, you’ll always be able to sell these for a good chunk back later on if you ever need to.
Also, I’d imagine with proper tune, you’d get around emissions. The visual will never catch these with how recessed the catalytic converter is in stock location. So as long as you’re not throwing a code, you should be good.
I see, good point on the resell value. I think I will keep the S5 indefinitely and just add to my garage in the future; I love this car too much!
I wonder if JHM can special order/create these in 2.75" sizing.
Jake any idea?
I think you mean rasp. Resonators may cause you more drone believe it or not.
very true…they would eliminate rasp but would make it miserable in the cabin.
anyways, i loved the rasp of my old car. the popping and burbling was intoxicating.
Bigserve…car looks great. I love the satin red!
Definitely meant drone, resonance inside the car that is like a hum! Even my center light console with the sun glass holder vibrates and shakes. Bluetooth phone calls piss people off so much that certain family refuse to talk while im in my car.
I wouldn’t mind rasp but it only seems to happen when the car is cold, during the first few minutes of drving
If my non-res really has less drone than the res then im glad, because I would have like gone back to stock if the drone would have been even worse!
Thanks 91gl! Are you back in the Audi scene?
Very nice post Big. I’ve been thinking more and more about replacing the S4 with an S5. I’d love to see the car in person one of these days. And as we’ve talked about before, it would be fun to do some pulls and see NA vs SC at Utah altitude.
I also have FI exhaust and the JHM stage IV clutch and FW. You could take a drive in my car and see first hand the sound and lack of chatter.
Hopefully JHM puts a supercharger on their in house S5 soon. That would be cool.
Thanks! Definitely, I would like to do some pulls since the RMR is closed for the winter. Do you have any test results for you current set up? I am still very busy, however, studying for boards and job hunting right now so Im more flexible to meet up. Shoot me a text when you have some time
Im sure it is in the works 
Been a while since I last updated.
About ten days ago when I got into my car to start it as I depressed my clutch I heard a quick sharp pop. The car started fine but clutch did not return, and that’s when I immediately thought “OH SHIT! FUCK ME!” Car would not go in gear, although I could easily physically bring the clutch back to no avail it was flopping around like a fish out of water.
I had to get it towed the next morning out of my work’s parking garage. Flat bed truck could not get it, so I grabbed my intern and we pushed it out. It goes to the local shop I have exclusively used for the last 7 years. It sits…I visit the shop the next day and I get the “your car is next after we free up this lift from our race car”. It continues to sit, no phone calls…5 days later I had enough get it towed to another shop that has frequent R8, and supercharged R8s etc…
Within 3 hours they find my brake fluid like tar which has corroded the rubber line between the master and slave cylinder bursting the line. $700 later the car is functional, but the clutch is still hard to depress the final 2 inches of travel (this has been a growing issue for the past 6 months). They bleed the lines some more hoping it is just air. Still difficult to depress.
Turns out there is a fork piece, pilot bearing, and another part that needs to be replaced. I also elected to go stage 3 clutch, which what is in all the supercharged R8s and 600+ ft/lbs of torque cars they do.
The flywheel drops me 4lbs of rotating weight.
Finally I said since its right there lets just slap on some JHM test pipes too. But I just realized the AWE track exhaust + downpipes are narrower than the 2.5" test pipes…I hope this doesnt cause some awkward air flow dynamics and sound…
I’ll update this once I have the car back

Those are Renn Motorsport 20 lb wheels! Forgestar are no longer
How’s the wrap holding up?
Also, what clutch did you get?
Wow smaller then 2.5" that sucks. Those jhm pipes should help wake the car up. How big is the awe exhaust. You would have to think they know better then to do the 2.25 thing. Cool update.
Contact JHM or Fast Intentions and see if they will get you a true 2.5 inch exhaust. There is a local guy to me that has a FI exhaust and it sounds great. AWE necks the pipes down to reuse the stock clamps from the end of the downpipes and the beginning of the catback.
