Ark Performance - High Flow Cat Test Pipe - Kia Optima

Fits directly and packed very well. It was made from high quality material and I definitely got better gas mileage and no rasp with my muffler delete.

INSTALLED on 2011 Hyundai sonata 2.0 Sounds great, better gas mileage.

I'm loving this on my 2014 SXL! Had it installed by a local tuner who took less than 80 minutes to do the job with no fitment issues. The test pipe is only slightly louder in and outside the cabin with little to no drone. I immediately felt better throttle response and a smoother power band. I get no codes level under full throttle. It compliments the DT-S very nicely. David was most helpful as he always has been. K5OS is a quality vendor who stands behind their products and services. Definitely my preferred place to shop for my Optima, thank you guys!
