Cats or No Cats w/ Roe S/C???

[bwhitmore]

Just taking a poll of those Roe S/C owners with and those without cats.

I think my ceramics aren't going to last long (well, certainly my side sills won't take with the heat anymore), so it's either no cats or metallic substrate at the very least.

On boost, the more you flow, the faster you go!

I have metallic, no problems here.

No cats if you can get away with it from an emissions point. Metal substrate if you can't.

I agree with Jim. You could melt stock cats.

I had RT H/F cats and after one year started to spit pieces out the tail pipe. No cats now

No cat's here and no heat eather.

A word of caution.....no cats = louder depending on what exhaust you have. My exhaust was real tame in the sound department and w/o cats I lasted two days.

I suggest replacing them with a muffler. I used the Moroso Spiral flow. Cheap, perfect size, great sound with no resonating.
