Customer Testimonials:

      Customer service was beyond perfect at Full-race. Technical support (Geoff) was awesome, he explained and answered all my questions about fitment. Corell, in sales, gave the absolute best customer service I had ever received from a vendor. I had millions of questions but he answered all of them without hesitation. My experience installing the exhaust was incredible, everything fit like a glove. This exhaust was the best after market exhaust I had ever installed. Me and my friend was absolutely astonished at how perfectly the exhaust had fit. It was simply one of the easiest and stress-free installs that I had to work with. Overall the process took about an hour. The hardest part was actually taking the OEM exhaust off the car. I will purchase a downpipe from them in the future and hopefully a turbo kit :P. Thanks again guys and great work!

Application Notes:

  • All models may require slight bending or modification of rear heat shielding during install
  • Gasket supplied is for use with aftermarket downpipe. If using OEM downpipe, reuse OEM crush gasket
  • During install, inspect small brace to ensure there is no interference. It can be removed or spaced down with washers. Aftermarket low profile hangars can help fitment.
  • Acura ILX fitment requires slight trimming to the rear plastic lower bumper cutout
  • Lowered vehicles may have issues with spring contacting the exhaust.
