Guys, I did an installation (retrofit) on a Ford 514 CID Factory Five on Saturday - a local guy's car in his garage. We did this on the car so we could get actual alignments & fitting. It took us 3 hours & the car owner did not have an air compressor. He went with the 3024-CP mufflers & will see a noticeable improvement. Wait til you see the entry into the mufflers after we chopped the collector & muffler apart - this is the kind of stuff I've been talking about. Also, the muffler cores looked to be about 2-1/4", so we stepped up to 3". After our tack-together mockup, he's going to take them to a welding shop & have all the seams finished with professional TIG welds, then have them ceramic coated. I got everything over to my web builder last night - a pretty nice series of photos. We will have a whole new page dedicated to retrofitting a Cobra with COBRAPACK Mufflers. This should all be up in a few days. (

Also, the reason why Kinetic had such huge gains in HP & torque, is because they had been using the stock Cobra mufflers which had under a 2" flowpath. On their high HP motors, this was REALLY choking the motors - they could not exhale. When they did this dyno testing, my 3" core mufflers were even more of a restrictive design than they are now - now they are very clean & maintain a consistent diameter. The same tests now would yield even better results. Chris Gesek (one of the owners of Kinetic) furnished me with the dyno #'s. There was no fudged data. Shows you just how important it is to run good flowing mufflers!
Thanks, -Eric
