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.

Great product
Size: 9.3" x 9.7" x 1.8"
I recently installed the BOSCH 6029C HEPA Cabin Air Filter, and the difference was noticeable right away. The air inside my car feels much cleaner and fresher, especially when driving in traffic or through areas with a lot of dust and pollution. It does a great job filtering out odors, pollen, and even fine particles—I’ve had fewer allergy issues since switching to this filter. Installation was straightforward and only took a few minutes, even without much mechanical experience. The build quality is solid, and it fits perfectly without any gaps or issues. Compared to standard cabin filters, this HEPA version is definitely a step up in terms of filtration performance. Overall, I’d highly recommend this to anyone looking to improve their in-car air quality. It’s a small upgrade that makes a big difference in comfort, especially for daily drivers or people sensitive to allergens.

Good quality!
Size: 9.3" x 9.7" x 1.8"
This cabin air filter is seriously a game-changer for my car's interior air quality. I was getting tired of that stale, dusty smell every time I turned on the AC. Swapping it out was surprisingly easy, and the difference was noticeable almost immediately. It really does trap all those tiny particles, like pollen and dust, that used to make my allergies flare up. Now, the air inside my vehicle feels so much fresher and cleaner. I've been recommending this brand to all my friends who are looking for a reliable filter. It's definitely worth the investment for a more comfortable driving experience. Seriously, if you're on the fence, just go for it!

Noticeable upgrade in air quality and a seamless installation
Size: 9.3" x 9.7" x 1.8"
I'm generally skeptical of the "HEPA" marketing for automotive filters, but after installing this in my Honda, the reduction in exterior odors—especially exhaust and pollen—is actually significant. The construction feels far more robust than the flimsy OEM paper filters I’ve used in the past; the pleats are dense and well-reinforced, which gives me more confidence in its filtration efficacy over a 12,000-mile interval. Installation was straightforward and took less than five minutes. It’s a precision fit with no gaps around the edges, ensuring that all intake air is actually being routed through the media rather than bypassing it. One thing to note is that you might notice a very slight decrease in max fan velocity due to the increased density of the HEPA material, but the tradeoff for cleaner air is well worth it in my opinion. If you live in an area with high pollution or suffer from seasonal allergies, this is a legitimate quality-of-life improvement for your daily commute.

Exact fit!
Size: 9.3" x 9.7" x 1.8"
Was a great replacement for OE on my 2012 Honda Accord. It was the exact same size as the previous filter and has no strange smells or odors. Very easy to install behind the glove box and looks great!
