I have a similar setup but with the FI LTH's and LOVE the sound since it's distinctive even when in a group of other cars with FI exhausts. It's quuuuiet for cruising, but let her rip and you get juuuuust enough rasp to let people know you've done more than just a CBE but in no way annoying. It sounds ever so slightly exotic and turns heads everywhere I go.
The best part is (
and I know some people don't like it) but the deceleration hiss, or hiss after coming off the gas in lower gears... sounds
almost like it's boosted. So even the cars that I myself wouldn't think of competing against because they
ARE boosted even lower their heads...
I love F.I.
