  • Features 2.5-inch mandrel-bent tubing for maximum exhaust flow and performance gains
  • Includes Kooks GREEN high-flow catalytic converters with 300-cell metallic substrate
  • EPA-certified catalytic converters meet Federal emission standards and help prevent check engine lights
  • Designed for use with Kooks Gen3 HEMI swap headers
  • Torca Swivel Seal style connection for secure, leak-free installation
  • Handcrafted in the USA with precision CNC machining
  • Backed by Kooks Limited Lifetime Warranty to original purchaser

Application Notes:

  • Specifically engineered for 2006-2018 Jeep Wrangler JK (all models) equipped with Gen3 HEMI engine swap
  • Must be used with Kooks HEMI swap headers
  • Due to the custom nature of HEMI swap installations, additional parts may be required for proper fitment
  • Not CARB certified for use in California or states adopting California emission standards

Kooks Headers has been the leader in high-performance exhaust systems since 1962, with over 50 years of proven expertise in racing and street applications.

Excellent service

great

What I thought would be a nice and easy purchase didn't quite turn out that way. I ordered the Holley fuel pump module for my 1999 Chevy Suburban K1500, because I wanted an upgrade from OEM to take advantage of the mods I have done to my truck. Autoplicity was the only vendor that offered a cost effective shipping upgrade: $60.98 for Next Day Air UPS, plus they showed the item in stock in their warehouse. The next day, I received an email confirming my order, but never reflected the item being shipped. I called customer service later in the day, but was told that the warehouse was already closed and that I could expect a shipping confirmation email the next day, which would have been Thursday. I had originally ordered the pump on Tuesday night and had my truck towed to my garage Wednesday late morning. I had alerted the shop that I had ordered the part and expected it Thursday, so they could install it and get my truck back by close of business Friday. It wasn't until late Thursday morning, when I once again had to call Autoplicity customer service, that I learned that the warehouse had made a mistake and sent the pump UPS Ground with the tracking showing delivery by Friday end of day. I finally received the pump around 1 PM Friday, and was luckily able to deliver it to my shop and have the install done that afternoon. I am giving 4 stars because the end result was that I got my truck back Friday evening, waiting for the Holley pump was the right decision in terms of vehicle performance, and Autoplicity refunded me my $60.98 for expedited shipping. I will consider them in the future for my auto parts needs.

Great

Great price!

You guys have definitely earned my business....THANKS!

Pricing the best. Easy payment through Amazon acount.
