Is that GTX even running? IMO, there is too big a difference in recording quality to even consider that a valid comparison. No way they should be that different.

IMO, Super Turbo it. $110 for a pair. You already have experience with those and are happy with them on the Satellite. At 2.25, I'd guess they may be just a skosh more quiet. If your unhappy with the sound on the Hemi, then Ultra Flow it at $170 a pair. Heck, buy both and your still only 50% of the Accurate system mufflers. Sell off whichever pair you don't want and recoup 90 percent of your money back. You then will have a side by side comparison you can use to come back here and use to convince someone to buy what you don't want.
