KO Racing R1 Exhaust System 3SGTE MR2

R1 Exhaust
R1 Exhaust
TKO 3" vs. R1 Dyno

NOTE: There may be additional delays to ensure the silencer fits in dealing with warranty replacement on the mufflers.

This exhaust is fully 3" diameter TIG welded from 16 gage 304 SS piping with 3/8" thick 304 SS flanges. The Vibrant Performance muffler is 100% robotically TIG welded Polished 304SS in construction with a removable SS silencer included. This is the exhaust showed identical results in dyno testing versus the 3" TKO. It has a very aggressive tone and is quite loud, but can be extremely quiet with the silencer installed. This system weighs approximately 18lbs TOTAL! You WILL get noticed with this great sounding exhaust installed on your MR2 Turbo!

For videos of the R1, go to our Movie Clips.

Note: You will need to modify the rear grating on the right side where the muffler sticks out as it will have a slight interference. The same applies for any body kits or aftermarket rear valences.

NOTE: This exhaust replaces the factory b-pipe and rear muffler from the primary cat back (or downpipe back). Use of this exhaust may or may not meet your local state and federal regulations regarding emissions compliance. Check with these governing bodies if you are unsure as to the legality of modifying your vehicle with the installation of this system.


COULD TAKE UP TO 2-8 WEEKS TO BUILD, (depends on lead time for the muffler/tips/flex).
