Cuts noise, but robs power

February 19, 2013
I tried these on my ultra4 offroad race rig and they cut noise, but cost 16 rear wheel HP. I had them mounted at the seam between the collector and muffler. On top of that the engine tune was way out of wack when we added them. I am sure results are purely application specific, but after 1 dyno pull I removed them.
No, I would not recommend this product.

Some possibilities, tack weld the insert to the inside of the collector. Modify header collector caps, 3 1/2" with an opening, perhaps 3"to 31/4" to retain the insert, which can be removed easily by unbolting the cap. Just a few things to think about,.

You would need inserts for 2.5" pipe.

We offer this insert for 3" or 3-1/2" tubes. We currently do not offer a insert for 2-1/2" tube.

Let's face it, open exhaust is a thing of the past! Sound requirements, mandatory mufflers, or maximum db level are found in all forms of racing today. From Mini-Stock to Outlaw Sprint Cars, reducing the sound level is becoming the norm. Today's racers are spending thousands of dollars to go racing. The last thing they want to do is get put on the trailer for too much noise. The Vortex Insert Cone can help you keep on track. That's sound insurance!
