Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars. Thus, removing as much exhaust flow restrictions will increase horsepower and torque.  The factory resonators found in the factory midpipe is designed to muffle and quiet the exhaust flow however this causes a restriction to the exhaust flow.  Our Sports Series Resonated Midpipes replaces the restrictive factory resonators with free flowing resonators.  We designed our Sports Series Resonated Mid Pipes to have a quieter sound similar to factory.  The ideal solution for  those who do not want a louder exhaust note than factory or have aftermarket downpipes/exhaust systems that are too loud while still providing a performance upgrade.  Coupled with mandrel bent tubing which also helps promote better flow, increase horsepower and torque can be had.  

Our Sports Series Resonated Mid Pipes feature a "H" style crossover.  The crossover is used to equalize the pressure between the left and right exhaust pipes.  This helps promote better flow and reduce droning.  Through testing between an "X" and "H" crossover design, we found the "H" crossover design helped reduce droning and improving low end torque compared to the "X" crossover design.  Thus, we incorporated an "H" crossover instead of a "X" crossover.  At the end of the day, this is a BMW and we do not want droning.  The factory mid pipe also incorporates a "H" crossover design so we figured BMW also felt the "H" design was the ideal solution for this application.  

Our Sports Series Resonated Mid Pipes are constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in-house fabricators and built in the USA.  Our exhaust flanges are billet stainless steel that is computer CNC precision cut.  The factory bracket hanger is retained.  The bracket hanger is laser cut and TIG welded using stainless steel rods.  High quality exhaust clamps are used to joint the mid pipes to the rear exhaust muffler section.

Our Sports Series Resonated Mid Pipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system designed for compatibility to the factory mid pipes.

Sturdy and Easy to Move
Color: Black, Size: 132"- 6 Panel
This 6 ft black partition on wheels is exactly what I needed to divide space without sacrificing style or stability. It’s sleek, professional-looking, and blends in well with any environment—from office spaces to home studios. The build quality is impressive—very sturdy and doesn’t wobble at all once it’s in place. The wheels glide smoothly and lock securely, making it easy to reposition or keep stationary as needed. Assembly was quick and straightforward, with all parts clearly labeled. Overall, this partition is a perfect combination of functionality and design. Highly recommend it if you need a durable, mobile room divider that looks great and performs even better.

Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!

Good product, poor directions.
Color: Black, Size: B-88''W-4 Panel
The quality of the product was better than most at this price. The directions could have been much better even though I have an engineering background.

Nice partition for my basement
Color: Beige, Size: B-102''-3 Panel
This 3-panel room divider showed up well-packaged with all the parts and even a little tool for putting it together. The instructions were easy to follow, and while one person can definitely assemble it, having two makes it quicker and less frustrating. It does exactly what I needed—gives quick, easy coverage in an open area. I'm using it in my basement to hide the furnace and water heater, and it works great for that. It looks nice overall, but I picked the beige fabric (which is really more of a tan), and the black frame makes it stand out more than I’d like. A white or lighter frame would’ve blended better. Not sure that I would use it anywhere besides the basement It’s lightweight and pretty sturdy. The wheels make it easy to move, but it does get a bit wobbly, and the panel clips need to be readjusted every time you roll it somewhere new. Still, for the price, it’s a solid buy. I’m happy with it and planning to order another one.

Fantastic
Color: Beige, Size: A-132''W-6 Panel
I am perennially in the process of rearranging, reorganizing, getting ready for yard sales, changing the functions of various rooms, moving everything out of a room to do a deep clean, etc, which means that there is always SOME part of my house, if not the entire thing, that is a disaster zone. Having someone knock on my door triggers a "duck and cover" reflex because it's so embarrassing for anyone to see that I live like this. (I *feel* like I don't, really, because I know that all the various stages are all temporary, but when there's always something temporary going on, it might as well be permanent, you know?) So THANK HEAVENS for a room divider that is not only large enough to divide my uncomfortably long den in half the long way so I can shove all the messy parts up against the back wall -- that is not only simple and attractive and neutral and (this is important) NOT BLACK because I have multiple pets and anything black in this house will be pet-hair-colored within 20 seconds -- that not only has **SIX** panels for lots of options of how I want to divide the space/s -- but is also on WHEELS. Someone out there really does love me, it's true! The panels are stable *enough* - I'm not going to lie and say that nothing is going to knock them over, because I have some balance issues, and I also have cats, and both of those circumstances has resulted in a mess on at least one occasion. But in the cats' defense, they've never dealt with a room partition that didn't hang from the ceiling before; and in my defense, I just grabbed the first thing I could reach on the way down. Not the product's fault in either case. Assembly was a little dicey as I am currently in **bilateral** (oh yes, that's fun) wrist braces, so I had to give up until I had help. But I think if you're able-bodied, you shouldn't have any difficulty. The only down side is, now that I've hidden away all the mess so I can break out the holiday decorations, you know what happens next, right?? That's right... the PERMA-MESS ZONE. Oh no. Oh well.
