Replace your standard catalytic converters with the COLORADON5X / Toyota Supra / BMW B58 downpipe to get rid of the backpressure they cause. Your turbo can now spool even faster and produce its maximum power by upgrading to our 5 inch downpipe. Your automobile will also sound much nicer as a bonus.

Expect a boost in horsepower of up to 30HP from a tuned BMW or Toyota Supra B58 with the factory turbo; cars with improved turbos will get considerably more power.

The stress and unwelcome vibration brought on by heat and engine movement will be lessened thanks to the flex pipe section.
