SPANKY LS1

How does a stock catback sound with LTs and ORP? Good or bad, raspy or clean, deep or high pitched? I have Hooker headers, orp, and catback currently, but want something quieter. How well does this combo sound? Or would be better off with a SLP 2OTl or Dual-Dual?

Thanks, Shawn

anything is going to be loud with an ORP. Some people install a bullet muffler in the I pipe to quiet it down some. or you could install cats, which quiet it down too.

Our SS has the Hooker LTs and ORYP ... I previously had the Hooker Catback as well, it was too loud for normal driving. I swapped back in just the OE muffler and it was ... almost the same. The sound level is not much lower, kind of sounds like a healthy catback system, louder than the OEM manifolds and cats with the Hooker catback, that's for sure. That will be our future setup shortly ... again. You can go to her website, the link in in my sig, for videos of our SS. I can't recall if we have a video with the cutout closed though.

The factory cat-back sounds so good to me with headers/ORY that Im going to do it to mine when I get one.

After I installed hooker headers and ory-pipe I still had the stock catback.
It wasn't an SLP catback either like the TOTL, just the huge stock muffler with duals.
It was honestly about 1dB louder with LT headers and ORY-pipe as compared to the catted cast manifolds. Very quiet, and still sounded stock because the stock muffler is so huge and decently restrictive.
