67 Im not sating your knocking me I am just saying your not armed with the knowledge you need about this subject matter. WE ARE PROFFESSIONALS, we took the time to deal with this system which is quite different from most out there, especially when you have a car where the mufflers are at the end of the equation like the Marks.
We tried Magnaflows, Dynomax, all of them, we couldnt get a happy medium, either too much tq and no hp or vica versa, thats when we decided we had to do something about this ourselves with a truly unique design that has never been offered to the general public, the Twiin XX Pipe torque chamber.
We tried one x, h pipes and NOTHING would kill the drone, then jeff at Ford Racing told us about a unique trick they did with the early 32v prototype Thunderbirds (They ran the 32v in the MN12 before it was used in the Marks FN10 chassis for driveability issues and what not) and he spoke of them hand making twin xx pipes to solve this he also noted that they had a slight increase in torque at lower rpms from this too. So then the twin xx pipe from LMS was born. We also tested MANY chambered mufflers as well with terrible results, you have to remember something, the 32v is a serious air mover, I mean seriously fast exhaust gas speeds come from this engine and the chambered mufflers KILL this in these cars, muffs like Flowmasters which I always will and still do say is the worst muffler for this car based on dyno facts and what we have seen, dont get me wrong they sound mean but do want to just SOUND mean and not run MEAN? I Love them, they just belong on pushrod motors.
We had some help from Jeff Dunn at Ford Racing with our exhaust product too, so it is backed by Ford btw. Its cool, you can call Ford Racing and ask anything about a Mark VIII and see whos number they will give you. We are THE ONLY Lincoln tuner endorsed by Ford Racing.
