Application and Installation 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 or replace with new
  • During installation, inspect to ensure there is no interference or contact.
  • Typically OEM exhaust hangers sag they wear out and allow for unwanted movement of the exhaust as they’re made from soft rubber, which can cause fitment issues. Torque Solution 12-15 Civic Exhaust Mount Kit is the recommended option for replacement.
  • Lowered vehicles may have issues with the rear spring contacting the exhaust. Use Torque Solution 12-15 Civic Exhaust Mount Kit to keep the exhaust in position without contact and prevent rattling.

Customer Testimonial

"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 were 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. Thanks again guys and great work!"
