Need Exhaust Advice - HF Cats and Cat-Back for OBX LT's - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

bmrandall87 · 01-05-2012, 12:25 PM

Hi guys,
I could use your expert opinions, vendors included, on how to finish my exhaust setup. Here's my current configuration:
OBX LT's (let's avoid the bashing here please)
Off-Road Mid-Pipes (no cats)
Stock LS3 Cat-Back
JRE Tune

Here are my goals:
Want cats to be emissions-legal and avoid exhaust smell my wife hates
Want cat-back/mids setup with no drone

So far, I have considered the Doug Thorley cat-back, as that seems to be an affordable solution, but I'm not sure what to do with the mids. I'd prefer something I can bolt on myself over having to weld on generic cats.

Any suggestions are much appreciated, thanks!

I'm running exactly the same thing. OBX longtubes, offroad midpipes and stock cat-back. I love it!

Get some OBX cats (or Kooks). I never found a drone free cat-back.
