For anyone who has this, how does this compare to the Greddy Sp2? Which is louder?

Also, for a base rsx, its $30 more, I'm assuming that's for the extension to fit a Type-S exhuast on a base.
With the extension, will the exhaust stick out a few inches from the bumper like the old greddy systems with the extension for a base rsx?

Thanks.

I like the SP2 better. I think the quality is better too.

Hope it helps
