Are any of you using KBD Targa Mufflers?

If so how loud are they and how bad is the resonance?



The beast has no cats and Flowmasters. I have tried X pipes, H pipes, extended the tips past the rear bumper, and have put in a crossover pipe just ahead of the rear axel. I can move the resonance up and down the RPM range from about 2100 RPMs to about 2700 RPMs but I can not get rid of it.;help
 
Sounds like you've been through what I've been through. I have gone through Flowmaster, Borla, Hooker, and a few more. Took them all off and for now, put the stock mufflers back on. I cant stand the stock, but at least a I can drive the thing without taking Advil!
I just received info on Magnaflow "True Dual" mufflers. I have recently heard from a few folks that this is the one. I called Magnaflow dirrect. According to them, this is the muffler with the best performance as far as resonance. I am ordering a set today for my 95. $399.00 for a dirrect bolt-on sound pretty good to me.
 
I have the KB targa mufflers and when I installed them onto the stock exhaust system with the cats it had no resonace and deep sound.
Then I install long tube headers with no cats and like you I have tried balance tubes and evrything to reduce the resonace. My car is louder inside than out but it has been that way for three years now I have learned to live with it.
