Rasp!!!!
I have the SLP Dual Dual Muffler with LTs and ORY. Its a little Raspy when you get on it but its not bad at all. I have considered adding a bullet muffler after the Y to lose the rasp but I am afraid that may quiet it a little too much.

Kook's LTs with cats and GMMG. That's my set up and there is ZERO rasp. If you want to put headers on GMMG you'll need to go with any grott design.....Kook's, QTP's, FLP's......and you must run cats.
Spurtle,
I have long tubes and ORYP with my Dual/Dual and it had a little rasp. I installed a Moroso Spiral Flow bullet in the I pipe and it got rid of most of the rasp but it did quiet it down a little too much. Now I wish I would have dealt with the rasp!

Do you have the dealer add-on optioned SLP Dual Dual or the SLP Performance Parts Dual Dual that you purchase directly from SLP or another authorized dealer such as some of this sites sponsors? I have heard the two differ from one another. The factory optioned Dual Dual is considerably quieter then the aftermarket (if you will) Dual Dual. I heard several audio/video clips of Tony's (Nineball) Formula when it had longtubes, O/R pipe, and the SLP DD....I thought it sounded really good(hardly any rasp).
The point of my statement was.. ALL longtube offroad y-pipe setups will have rasp. IMO, the Dual/Dual does the best job at taming it.
BTW, I love the sound of the Dual/Dual on my car. FWIW, the one I have is the factory optioned one (off a friends Firehawk).

I can handle it like it is, I am already borderline too quiet. TECH Resident

I think everyone has a little different definition of rasp. Mine makes the raspy sound slightly as the engine crosses 3000rpm under heavy load...light load and it wont do it and after 3200, its gone. Setup in sig.
Do yourself a favor and install a true dual set up now. I had to stick a dynotech bullet in the I pipe to kill 90% of rasp. It sounds much better but I have 2 ranges of loud. At full throttle it sometimes sound good but sometimes if the flow is interrupted still get raspy and crazy loud.
