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.

Great toy for puppies!
Color: Turtle
I love this turtle. My toy poodle puppy has boundless energy. She loves this thing. It keeps her busy so I can get laundry and other things done. I am buying a second one for when the first one loses its charge😂

It broke within the week
Color: Turtle
The toy was ADORABLE, it worked very well for the first week. And then it broke. I bought two for my puppy and my 8 year old shih tzus. It stopped vibrating and just made loud grinding and squeaking noises. I would recommend this toy if it lasted longer.

Offers tons of activity
Color: Turtle
My 70lb dog LOVES this turtle toy, was worth the price. He will play and play until he’s exhausted. We have to give him breaks from it. We use the second setting which is just for movement, no music. The only aspect I don’t like is that he will inadvertently press the button when he’s biting the toy, changing the setting and sometimes has turned it off. The velcro is super strong, which is good but makes it difficult to open. Battery life is decent, lasted a few days with him playing with it an hour or so each evening. I like the auto shut off after 30 minutes of no movement.

Great toy for a dog who is not afraid of noises
Color: Crab
My puppy loves this thing! She was confused at first but now she plays with it daily. I just let it jump and sing the first time. She looked at it with the cutest head tilt. It is a bit loud so if you have a dog that's scared of noises this might be the right toy. Now when she picks it up, I turn it on and she gets so excited! The different songs make the toy less annoying for me, lol. Honestly, anything to tire out a 4 month old puppy. She is very entertaining to watch.

What a fun toy!!!
Color: Turtle
This is the first toy in a very long time my 10yo GSD wants to play with. She actually brings it over for me to turn on. It is loud and wiggly... She goes nuts for it! So far good quality with shaking and light chewing. Very easy to turn on and off. Great value for the play enjoyment of my sweet girl, gets her up and moving.
