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.

Wide toe box
The color is pretty on these water shoes. The toe box on these shoes is wide which collects water making it difficult to use them walking for exercise in the water. I bought these specifically to keep my feet protected. The sole is the perfect thickness needed but can’t use them for what they were bought for.

Good and affordable
Size: 6-7 Women/5-6 Men, Color: 1a-stripe Black-2
Pretty good and effective for the price! I wore these to volcano bay in Orlando and they got the job done. While these water shoes have great comfort, traction, versatility, and water resistance, they don’t have a lot of support on the sides of the shoe. They also are tight/snug around the ankles. Theyre very lightweight and can bend and fit in a fanny pack or purse, but if you’re looking for a supportive water shoe, these aren’t it. But if you need something to just get the job done so you can have fun, these are it!

Solid and comfy
Size: Medium, Color: Black (001)/Jet Gray
Absolutely love these sports bras. They’re simple and solid, and I love the colors! They do run small, so I’m glad I sized up. I’m usually a small, but got a medium and they fit perfectly. For reference I’m 5’5”, 125lbs, 34B. They wash well too! Just make sure to air dry them and wash on cold only.

Great bra, poor customer service
Size: Medium, Color: Black (001)/Jet Gray
I like this bra. It offers great support. But the sizes run small. I remembered this after placing my order. So I got back with Amazon two times within six hours of placing the order to cancel, so I could exchange it for a larger size. Amazon would not cancel the order. And they have no option for exchanging it. They used to allow 24 hours before processing an order. Not so here.
