**********s | Riss Racing Downpipes for the 135!! LOW INTRODUCTORY PRICE!! $699!!!!!

To those who love performance and want the most out of their BMW turbos, I've got something for you!!

[img]http://www.**********s.com/images/Products/Riss%20Racing/Riss%20Racing%20Banner.JPG[/img]
WE CURRENTLY HAVE A SPECIAL INTRODUCTORY SPECIAL ON RISS RACING DOWNPIPES AND THEIR PERFORMANCE PACKAGE!

Details:

For those that want the most out of your money, Riss Racing's Downpipes will provide extraordinary horsepower and torque for your BMW 135i--ERROR FREE. With its high quality, free flowing design, you can expect an additional 30WHP and 50WTQ with no other modifications!! R.R. downpipes start with 3" piping and transforms into a 2.5" piping to give your vehicle maximum air flow for maximum power. Corrosion, vibration and heat tested, this product will not fail you when you're pushing your 135i to the limit!

[img]http://www.**********s.com/images/Products/Riss%20Racing/Black%20DP%20(Small).JPG[/img]

Quality Overview:
From flange-to-flange, these are made from the highest quality 304 Stainless Steel, so you will NOT have to worry about rusting. Along with that, the design of these pipes make brackets unnecessary, unlike mild steel downpipes, which require brackets to move with the engine. Every set of Riss Racing Downpipes are corrosion, vibration and heat tested to make sure you get the highest quality product with the highest producing power!

Don't expect anything less than 100% perfect fitment with these pipes either! These will directly replace your OEM downpipes, removing the cats and creating more power for your 135i! You also have a choice between two finishes: 304 Polished Stainless Steel and Ceramic-Coated\. After several heat cycles with your 135i, the 304 Stainless Steel will begin to bronze to match the look of the OEM downpipes! Because the Black downpipes are ceramic-coated, it will hold more heat in the pipe, keeping the engine bay cooler--as a result, increased performance.



Finishes
* Polished 304 Stainless Steel
* Ceramic-Coated Black
* Special Custom Colors

Application
* BMW E90-E93 335i & xi
* BMW E82 / E88 135i

Features
* Unique 3" to 2.5" piping design
* Sounds great with the full Borla Catback Exhaust System
* ERROR FREE with an O2 Simulator!!!
* Fitment 100% Guaranteed
* 304 Stainless-Steel, flange-to-flange
* No rust
* No brackets required
* Corrision, vibration, and heat tested
* Extra wideband for tuning
* Compatible with major programmer products (e.g. Juice Box)
* Can be purchased as a package (Juice Box & Riss Racing Downpipes)

Express your Individuality
* Special Color Finishes Available
* Add a Juice Box programmer (+40 wHP, +50 wTQ!!!)

I'm interested, but have a question.

If the pipes go from 3" to 2.5" doesn't that make the 3" part a waste of space since the shrink to 2.5" will restrict it?

Thanks.

Nope. :smile: It starts at 3" tapers down to 2.75" and then to 2.5". Has been proven to easily make 20+ whp. I believe some have shown close to 30whp with just these DPs!

Thanks for the info. 20+ is a lot. Is that with a tune??

Also, my question still stands though. Is having 3" -> 2.75" -> 2.5" still a waste? Because 2.5" will bottleneck the rest??? Isn't that the same as 2.5" all the way through?

I'm not doubting the performance gains, I'm just curious about the tech behind them.

The flow characteristics with 3" flow will be much more different than 2.5" throughout. I've heard of some turbo Volvo race cars that had 4" downpipes which continually taper down to 2.5" making about 30% more power than 3" throughout. Gains on a stock car were around 30whp. Tuned, you'll see around 60whp bump with a downpipe map.

Hey Adam. Thanks for answering my questions here and on the other forum. I've heard nothing but good info about your products.

Is there any technical info anywhere on why what you stated is true? I've heard on different forums that the taper helps, but never why. I'm certainly down for getting a set when I finish the break-in on my new 135i when it comes. I'm just curies about the science behind it.

Thanks again. :thumbup:

Sure thing. If you google "downpipe taper" you will get a ton of information. Mainly, with the larger flow up top, you get even quicker turbo spool and much more potential power on the top end. This is a fact with turbo cars in general. Let **********s know when you finish your break-in, hope you can try em' out!

I am reading about it now. Thanks for taking the time to answer all of my questions.

Adam, can you show us a dyno chart that compares before and after? I am concerned that we will have a lot less low down torque as seen on some DP's.

I know this is just a dyno of the after, but I'm sure there's some dyno tests done already somewhere on the forum. I'll look around for you

You won't see less of anything with the catless downpipes. You will see a lot more down low torque. :roundel:

Exciting! If I had the 135i, I'd be all over this right now. You're getting such a great deal. Easy increase in hp/tq

When installing new DP's.. Does unplugging the battery make the ECU adapt better to these?

Unplugging the battery does not change the adaptation of the ECU. The ECU does live monitoring and adapts to the changes itself. Just drive around a bit, and get your ECU to understand and adapt to your new DP

So the ECU is capable of adapting to these.

Are you saying the reseting of the ECU is only for piggybacks then? I would think it would take longer to adapt to a change in the car if it has a history built into it.

The ECU recognizes the new DPs once it gets installed. It just needs some experience on what you're driving with. Reseting the ECU applies to other parts like the piggybacks, yes.

The ECU is capable of adapting to this.
