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 Competition Series Mid Pipes deletes the resonators from the exhaust system to improve exhaust flow.  Coupled with mandrel bent tubing which also helps promote better flow, increase horsepower and torque can be had.  At the same time, a more aggressive exhaust sound is produced.

Our Competition Series 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 appliation.

Our Competition Series 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 Competition Series 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.

Convenient and Cost-Effective Air Filter Set for Gasoline Engine
Size: CRV (2023-2025) 1.5L Gas, Size: CRV (2023-2025) 1.5L Gas
Why did you pick this product vs others?: The set includes both the engine air filter and the cabin air filter, which I find extremely convenient because both usually need replacing around the same time—especially if you drive in dusty environments or have seasonal allergies. Ease of installation: I replaced both filters myself in under 20 minutes using just basic tools. No instructions are included, but a quick search online brought up several helpful videos tailored to my car model. Both filters fit perfectly without any force or trimming needed, which isn’t always the case with aftermarket brands. Functionality: From past experience, replacing the engine air filter regularly (every 12,000 to 15,000 miles as suggested in the owner’s manual) helps maintain better fuel efficiency and extends engine life by keeping debris out of the combustion chamber. After swapping in the new filter, I noticed the engine ran slightly smoother—especially on acceleration. Smell: The cabin air filter is equally important, particularly for passengers with allergies or sensitivity to airborne particles. I could immediately tell the airflow from the vents was stronger and fresher-smelling after the replacement, which suggests the old filter was overdue. Value for money: The ITESIER Cabin and Engine Air Filter combo pack is a smart buy for anyone maintaining a gasoline-powered vehicle like my Honda Civic. This combo pack offers good value for money compared to buying each filter separately. Quality: Overall, if you’re comfortable with basic DIY car maintenance, this kit is a great choice. It’s affordable, fits properly, and provides an easy way to knock out two important maintenance tasks in one go. Filter quality: The filters are high quality. They work without problems. Just be aware that this is designed only for gasoline engines—it won’t be compatible with diesel or hybrid powertrains.

Exactly what I needed
Size: CRV (2023-2025) 1.5L Gas
I'm not sure how much there is to say about an automotive cabin air filter. I double-checked the specs to make sure this was compatible with my car, ordered the filter, then installed it. It fit, it didn't have a weird smell, I haven't thought about it since. That's exactly what I want in an air filter. Five stars!
