CTS Turbo CTS Turbo BMW F90 M5/M5C & BMW G15/G16 M8/M8C RACE DOWNPIPES are made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts.\n
\nDesigned using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance.
\n
\nIn addition to unleashing the power and performance of your 4.4 Twin Turbo, our race downpipe will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust "crackle" on downshift. While up-shifting you will enjoy a confident "punch!" as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.

A Coat That Doubles as a Physics Experiment
The coat looks fine, but trying it on felt like stepping into a physics experiment. The 100% polyester fabric generated so much static electricity that I honestly felt like a walking electrical generator. If you enjoy shocking yourself and everything around you, this is the coat for you. Otherwise… be prepared.

Weird pockets
Size: Medium, Color: Brown
It was a nice coat but the fabric was shimmery and the front pockets were very high. It was very awkward looking. Overall it was nice fabric and a good length but the pockets and the shimmer made it a return for us.
