Primary & secondary cat delete smell?

[Route 16]

Hey OP, with your test pipes and if you deleted your 2ndary's...did you notice if the exhaust sound was the same? I am all catless and the smell is getting to me but I love the exhaust sound. How much volume/rasp will I lose adding the 2ndary cats?

Definitely more rasp with secondary delete, at least with my setup. I have oem modded muffler and primary and secondary car delete with oem resonators. When I had test pipes with oem modded muffler I thought that the sound was perfect but needed more loud.

I noticed a huge difference in smell when I switch from my stock xpipe with test pipes and secondary cats in place to a hfc ess xpipe. It's usually only at cold start.
