Does it feel any different in power delivery? Do you have a boost gauge and if so does it appear to be getting into boost any quicker? Or, is it purely a sound difference?
I was thinking of doing the same thing but with a high-flow cat and a different downpipe or as they're also called 's-pipe'.
So, it'd be downpipe to mid pipe with hf cat, then what you have. I'm just waiting for Corksport's d/p.
Thanks for posting the clips and the photos. Would be nice to see some underside shots as well.
