Hi Lostsoul.
I am looking at Ark GRiP vs DT-S for my 40th. I thought the DT-S was the louder of the 2 products? I have gone to Ark site and hear Sound clips of both.
Why did you choose the GRiP?

I know you aren't asking me but I just wanted to add my 2 cents. I chose the DT-S because of the muffler design primarily, and I also liked the overall tone of the exhaust better too. Looking back I think I would've still gone w/ the DT-S. It's a really solid piece. Besides, I've heard that one of the mufflers on the grip hangs lower than the other. Idk if ARK has fixed that or not but last I heard that was being discussed.

The Grip type2 v2 fixed all those issues. Mine lines up perfectly.

Would be interested in seeing this setup as I'm looking into the same direction.

From my experience, an exhaust set-up with test pipes sounds VERY similar to the same set-up with LTH's. Personally I went with the F.I. LTH's mated to the F.I. TDX CBE w/18" resonators. Here is a sound clip of mine...

Hope this helps :)
