My 2000 SS has the Random Tech cat-back and there is no drone or resonance at all. The muffler is a straight through with perforations to feed the passenger side tailpipe. You might want to look at actual muffler designs to help determine what might work best for you.
Hey Jeff! Thanks for the informative post. I have been looking at all the exhausts available and decided the 2.5" V6 cat back by Magnaflow is what fits the bill. The pipe size is perfect for a stock motor, and its all stainless so rust should not be an issue, and if the system fails, it is warranted for the life of the system. The muffler on this system is a straight through design, so it should be low restriction. I also like that all the packing is stainless steel too, so it should not burn, compress or blow out like fiberglass packing does over time.

I agree with your assessment on pipe sizes, way too often a system is fit to the car that is too big for the HP/CID, resulting in an actual loss of performance rather than the anticipated gain. From what I see on various forums, this system is perfect for my application.

Hopefully, this Maganaflow will not be too loud, or drone at highways speeds.

Thanks again.
