Product Details

The Kooks Headers 9912S is a premium 304 stainless steel slip-on collector designed to optimize exhaust flow and maximize performance in custom header systems. This universal 4-into-1 collector features a 2-1/4 inch inner diameter inlet that slips over 2-1/4 inch primary tubes and expands to a 4 inch outer diameter outlet for superior exhaust scavenging.

Key Features:

  • Constructed from high-quality T304 aircraft-grade stainless steel for exceptional durability and corrosion resistance
  • 4-into-1 design consolidates four primary tubes into a single outlet for improved exhaust flow
  • Kooks patented scavenging spike technology enhances exhaust velocity and reduces backpressure
  • 2-1/4 inch I.D. inlet designed to slip over 2-1/4 inch primary tubes
  • 4 inch O.D. outlet connects to standard exhaust tubing
  • Includes two A/B style mounting tabs to securely attach to primary tubes
  • Handcrafted in the USA with precision welding and construction
  • Sold individually for custom exhaust builds

Backed by Kooks' reputation for race-proven performance and over 60 years of exhaust expertise, the 9912S collector delivers the flow characteristics and build quality demanded by serious enthusiasts and professional racers. The T304 stainless steel construction ensures long-lasting performance even under extreme temperatures and harsh conditions.

Great

Search to ID the right part looks good so I bought. Sure hope it fits!

I just placed my order, and so far I've enjoyed my experience. The website is very easy to read, and technical assistance helped me locate my correct part. Fingers crossed it's clear sailing from here.

Easy search, easy cart.

I found this website to be awesome! Was the cheapest parts compared to other sites. Great products and the best available prices! GREAT PLACE TO SHOP!

Always been happy with products and price.

I'M A HAPPY CUSTOMER

!!!Thank you!!!

It was quick and easy to purchase and very easy to find the item I was looking for

Fast and easy.

Glad I found Autoplicity.com. Big potential...<br><br>Ordered parts on Friday, missed 1st delivery attempt to office yesterday (Weds), but received today (Thurs). Little slow on the shipping, but not in a rush for these parts. We typically receive UPS pkgs in 1-2 bus days from Chicago suburbs to Metro Detroit. This took a bit longer, but again - it was not a problem & well worth the savings.<br> <br>Wish web-site would actually separate items for just my car vs all vehicle matches. Finding what I wanted was very difficult, but I'm very pleased with pricing & follow through. I've been back on Autoplicity 2 times now looking for add'tl parts for another vehicle, but have yet to locate them amongst the 100's - even 1000's of results that do not match. If finding them were easier & these add'tl items offer similar savings, I would have spent hundreds more by now. <br><br>If this is a new company, hopefully they can correct the advanced search option as well. Entering a part by vendor name should net results when the brand is listed on the home page & can be found in general queries. Even when I entered the part # for an item it shows no results, but again - searching several dozen pages, I am able to find the same part #. The savings were worth the headache it took to find the brake pads for my BMW, so I won't give up just yet. <br><br>Thanks Autoplicity! Here's to a potentially great future!!

awesome price and super fast shipping. I will use again. Thanks

Autoplicity had the best price availiable for the product I purchaced. They beat all other competititor's prices!

Best Price i could find for some nice foglamps. easily navigable website.
