AR DESIGN OR RISS RACING DOWNPIPE

[7to1]

THOUGHTS???

AR IS TRUE 3'', IS RISS?

DYNO COMPARISONS?

[audi2bmw1]

great question

[Terp1]

I've been wondering the same thing. AR appears to be $100 cheaper on both Catted and Non-Catted. Unfortunately there aren't any posts in the Vendor's forum for AR either so we have no insight into products or customer service. Somebody needs to step up and take one for the team.

[audi2bmw1]

they claim its the only true 3in on the market...statement is prolly true since RISS racing and other companies dont list the diameters...hmmm wonder why...and what exactly is the stock Diameter....from the looks of the stock pipes they dont exactly seem to be under 2.75in but i would have to measure to be 100 percent...

AR probably makes quality products as does Riss. The reason for lack of vendor feedback is they are a newer player in the N54 products.

I like what they are saying on their site about the downpipes. Great marketing. But, then again, I'm easily sold! :biggrin:

Do you also want to bring Ultimate Racing into this discussion?

I've got the Ulimate Racing DPs on my car. Fitment was perfect and the welds looked great. I haven't had first hand experience with either of the other two brands, so I can't compare.

The only thing I ran into during the installation that was unexpected were the studs that couple the DPs to the factory exhaust. The original pipes have pressed studs. The UR pipes didn't have any, and I didn't want to just use regular bolts on them. We pressed the studs out of the factory pipes and put them in the new DPs, but it was a PITA, and it's not something you want to attempt in your driveway. I've got a friend who runs an exhaust shop, and he helped me put these on. Having easy access to a torch and press is the only thing that saved me with those studs.

I don't know if the other two pipes come with this hardware pre-installed or not, but it's something to consider. As far as performance goes, it's hard for me to imagine one will show signigicant, repeatable gains over the other. It's a pretty simple peice of pipe, and the design is restricted by the location.

AR down pipes go down to 2.5 inches just like Riss Racings, what they do is they taper from 3" to 2.5 Further from the turbos so that is what they are talking about with there 3" claim. You are hooking it up to a stock 2.5 inch exhaust so it would be impossible to do obviously. I have heard good things about the AR pipes and I have heard with an AE exhaust at dyno day and the sound was good. I have the Riss Racing Down Pipes on my car and love them, I installed them myself in my driveway with a jack and stands so the install is pretty straight forward. If you read my post on my install I had a problem removing some stock parts and that gave me a hard time. But installing the Riss Down Pipes were cake the fitment was perfect. They stayed on the phone with me for almost 45 minutes helping me take off the stock BMW stuff. You know I will say go with Riss since I have all Riss stuff but you really cannot go wrong with there products and customer service.

johnnyr is the best thing to ever happen to riss racing lol, he's everywhere singing their praises. or is he screaming their praises? he's starting to convince me though.

I just hate wasting my money, I have owned around 25 plus cars and made some big mistakes and wasted a lot of money. I an I have met some great people at the meets and the forums and if I can help with my experience I will. Riss gives me money, I bashed there intake on looks alone and put my foot in my mouth after I bousght the AFE and wasted my money and ended up buying th Riss and was happy. So I may look look like I am a huge fanboy, but I am not they are a small business in a bad economy and if they come out with a great product lets give the guys some credit and free press it is hard enough to start a new business in a market like this. The better they do the more products they will produce for us and the better products they will produce. I am sure they do not wnat to come on this board and an see a tread where I rip them apart for a shitty product. So I am confidenct we will get nothing but the best from Anthony and Riss Rassing.

We were the first to make a 3 inch downpipe. This shows the lack of understanding AR design has.

They have a 3 inch DP that has an abrupt taper to 2.5 at the flange. This causes back pressure and restricted flow since it causes a choke point.

We if you read back about a year ago worked with Shiv as we made a full 3 inch DP with the same abrupt taper. After re working the DP we found out that started at 3 inch going to 2.75 then 2.5 with a slow taper increased flow which increased power with no back pressure. Their design is the same concept we did over a year before they even started their company. I have nothing but respect for all vendors. However this company is ran by somebody with no respect for what other vendors do paving the way for the N54 community. He does nothing but bashes other vendors, and lets hope he learns business ethics as his company grows. Once again these are all facts. I can pull up posts from a year ago too prove this as well.

Do you mind me asking why you got rid of the AFE intake? I was thinking about getting the AFE (if I'm honest because it looks good). Cheers.

Breville, speak to Swift. Apparently it sounds rather ricey..

-----------------------
your saying yours goes from 3in to 2.75 to 2.5 taper? what are the stock diameters? why not 3in all the way..space didnt seem like that big of an issue...and did u do testing with a full 3in...i totally understand about backpressure but the turbos make up for it

Excuse me Anthony? You are responding to alleged "bashing" by shamelessly bashing me? Very nice.

I called you out on E90Post (and I will do it again if needed) because you posted information that was blatantly misleading, and in no uncertain terms directed towards ar design... I certainly hope you aren't referring to that, and for what its worth, you never replied.

In fact, now that I think about it, I just made some positive comments in Eric@AMS's threads, about their new exhaust, even though they will be our DIRECT competition. I am glad to point out a great product, even if my competitor makes it.

So I will re-state - neither myself or any other company has used your downpipes to make jigs, and we WERE the first TRUE 3" downpipe on the market -you tapered to 2.5" sooner, especially with your first revisions of downpipes. And we do not grind + weaken our welds. As to your false accusation of us doling out downpipes for free, we have not given any sets of downpipes away. Every set that has left our building has been paid for. End of story.

Please feel free to show me bashing "every vendor", and my lack of business ethics. Post up some links with pissed off ar design customers. You wont find any. Why? I have not had ONE unhappy customer. Flipside, a quick search on E90post might just reveal some really, really pissed off Riss Racing customers.

I also find it interesting that you are now including gaskets with your downpipes that look a WHOLE LOT like ours, which we started selling when most everyone else was re-using OEM gaskets with black RTV, and certainly long before you. :iono:

For what its worth, we have not had multiple revisions of our design, because our downpipes fit the first time, every time :smile:

This Riss Racing thing is starting to get on my nerves. It's RR this RR that all the time, I am surprised this whole forum isn't dedicated to them and the over active reviewers that sing their praises.

I suggest Antony and his team at RR simmer down and do what they do best and keep developing and selling their products and stop getting involved in forum banter. It looks unprofessional and doesn't help your image guys.

And while I am on it, all those guys on here with RR logo's in their signatures, who's going to seriously read your reviews and think for one moment your unbiased?

I'm calling Bullshit on you...If you had a "True 3" downpipe" you would have to have exhaust that was 3 inches as well... If any diameter of your diameter is less than 3", you are fraudulently misleading people about your product...

Riss has had a revision of their product for ease of install, not performance or fitment issues. Know what your talking about before you call someone out...
