Fact is there is nothing worse than working for days gathering dat and setting up test gear only to post it and have someone who reads tech articles with no practical application experience at all challenge it... That happens and I really don't have the tolerance for it, especially when giving the information away for free.

I already receive more crap through email than you can imagine from people that are still in denial that their engine can break... Some are down right nasty!


I understand and appreciate your view point. It is much like mine. The answer is you can get 1-3Hp from the headers more than likely, buit it won't be astounding.. And you might shear off 2-3 exhaust flange bolts during the install and that can cost you days or hundreds of dollars to repair.


That means you need a flatter torque curve and more mid range grunt... Something I have gotten from a chamshaft change or a valve timing alteration that deviates from stock. The exhaust system might actually hurt the performance you are looking for..


every car has some corner or portion of the track where the power isn't what it should be.


Unfortunately that 2% has a voice that is much louder than the 98%... If I were going to have to listen to flack for sharing information I should at least charge for it...

It really does suck for everyone... People only think I am trying to sell them something, hell I don't even sell an exhaust system!

Their is a perfect example of this non sense over on PPBB now, where a bunch of armchair wrench turners that have never touched our billet magnetic drain plug or low temp thermostat are challenging their effectiveness.. They are basing their opinions on assumption and are seriously piossing me off. I have the data and drive and test the cars daily that are equipped with the components.

Jake, as I told Charles, remember the old line about "leading a horse to water"......... Both you and Charles need to keep the faith and keep up your great efforts, for as you have seen, "they know not what they do........" We can only hope that they eventually wake up and see the light………..
