The thing I don't like even more is the tone with the stock muffler. I think it's very "blatty" and just off...hard to explain. This is mostly with the baffles closed. I had an '01 WS6 w/long tubes, no cats and borla. Loved that sound. Roared when WOT and reasonable when part throttle, but was still quieter over all and had great tone all round.
Any of you guys that did similar mods feel the same?
I know there are exhausts with the NPP option. Anyone go that route and feel it better? I know better is a subjective term.
Looking for a more consistent tone and actually would like it a little quieter.
Really don't want to go green cats as told they will eventually fail but understand they help take edge off the roar at WOT...
Thanks

I feel you. Been there done this with my SS. My ZL1 stock shorties will stay on. If I do anything it will be just a complete system that removes the rear cats but keeps the stock hookup. For the small amount of HP you get with LTs to me it is not worth it unless you are going big power. And it makes it harder to back to stock.
However at the track many loved the screaming wide open sound of the ARH SS. On the street it was not as nice with the boomy/blatty sound. Most of the time I ran in full time Stealth with my SS then open at the track. That wasn't too bad.
What I did with my LT NPP fifth gen 1LE was to add a resonator. This toned the sound down for that car. Smoother sound and much more pleasant.
