"some sound just not too much" = HFCs

test pipes!

Try it with the stock cats first the FI exhaust is loud by itself.

hahah go test pipes.....
right trips?

I'm kind of curious what my car would sound like with test pipes instead of the HFC's. My problem is that I like the idea of using cat's from the pollution and smell perspective.

Yeah I just don't want to be a stinky and polluting bastard.

I've probably owned more cars without cats (because I'm old) than not. They didn't smell. well, not from the exhaust, anyway.

Stock cats for sure. Kirkster has ridden in my car so he's not joking when he says the 18" is fairly loud as is.

If it's not loud enough for you then add HFCs.
