Benjie,
the Beaudesert Exhaust is supposed to be a good one. My setup is a lot different.
And it was intentionally different. The actual system is a Black Widow i think (been too long), i couldnt afford stainless, but i have the hi-flow CATs as imentioned and i have ceramic coated Pacemakers but a different end muffler.
Bullet Cars use a customised Genie set of headers/extractors, also ceramic coated at their recommendation, and you can buy the Genies from any Genie reseller. They are bigger than my Pacemakers in terms of diameter. If i do supercharge it and the Pacemakers don't measure up...then i'll need to get the Genies. However, Tom from Bullet said the Pacemakers should be fine at 5 PSI boost.
You will get performance and economy with the Beaudeserts and they will have had similar experience years ago with droning and there wont be any.
Double check over at lcool.org and do a search there.
Beaudesert advertise heavily on the 4WD Action magazines and their monthly DVDs. The sell a lot of exahust systems nationally.
Most people recommend the Xede piggyback ECU be installed and tuned in conjunction with a new exhaust, but at $1200 i couldnt justify it without the supercharger. I can see it rounding out my current install, ummm but nope...not at $1200.
cheers
peter
