I dont care about emissions, but i do care about noise. I want a free flowing exhaust to put behind an ls6, in a 2003 rcsb. Does anyone make a set of headers (long or short) and a matching Y pipe that has highflow cats and a 3 inch single outlet?

I see a bunch of oRYs with no cats, and a ton of replacement catted Ys, but none that are high flow.


Anyone?

 

pretty sure a lot of brands have the option of a catted Y pipe... OBX does for crying out loud.

 

After several different configurations, I settled on, (and really like), my longtubes with ORY and stock replacement exhaust. None of that crappy glasspack sounding rasp, and zero drone, yet still has a nice tone.

 

When I read your response I looked deeper into OBX. Originally everything i knew about them was from ebay. All the auctions sold a "resonator" instead of cat. So I assumed that was the best they had, but the OBX website shows a better version with 2 cats for $795. Long tubes and a catted Y for $795. Thats not terrible... So thanks for that suggestion. I am actually looking for a High Flow cat though.

I already have a 3 inch flowmaster muffler and turn down i was planning on trying out. Ill bolt that up to the 3 inch outlet from the Y and see if i like it.

The stock exhaust is a single 2.5 i believe, so its too small, but its quiet.
