Feels better without the cat, especially opening up to bigger downpipe (turbo).

I had a decat onto a standard backbox, and it sounded pretty raspy.

Here's my nur spec, no bung, decatted:

In terms of extra bhp, I found the stock backbox hugely restricting and it killed the cars enjoyment for me if I'm honest..

Correct. Mine is a HKS Superdrager, but not for an MR2 turbo. It has been custom fabricated to fit my car. :-$ :mrgreen:

The HKS Superdrager for an MR2 is twin exit :thumleft:

I can't say as I replaced as part of other work which would make it hard to discern. I can say the exhaust is noticeably more free flowing , and probably does free a few more ponies.
