This cone insert can be fitted inside your existing exhaust to bring down the volume without the need for extra resonators or mufflers. This insert fits directly into your exhaust, these slip fit in but you'll want to either use the integrated nut or tack weld them in. One cone will typically result in a 1-3 dB reduction of volume. 
  • 100% T-304 stainless steel construction
  • Compact size fits all racing applications
  • Ultra lightweight - less that 1/2 lb. each
  • Little or no power loss
  • Easy bolt-in or weld on installation
  • Typically good for a 1-3 reduction in dB

Quality product. Didn’t do what I wanted… my exhaust had a “chirp” to it when I put these in. Took them back out and wrapped steel wool around the cone and put them back in. Sounds like I wanted it to. Not sure how long the steel wool will last, but we will see.

So far good. I installed them on my airboat powered by a Lycoming 4 cylinder to meet law enforcement requirements, I have not taken the boat out yet, I hope they hold up.

Another excellent product from ZZP quick shipping very well made and hard to believe a simple item like this does what it does but the difference was amazing the repair shop welded it into the Magnaflow catback on my HHR which was way too loud & there was an immediate improvement lowered the volume considerably and also got rid of the annoying drone at a certain rpm I'd highly recommend this product
