I do, Currently got a Hayward & Scott decat downpipe, with a HKS Hiper 3" cat back system. But my HKS system is very old and has develped a leak where the exhaust meets the backbox. So i do need a new exhaust anyway, and it's either a Blitz system or the Roger Clark system.
In order for me to have the Roger clark system, i will need to upgrade the entire system to a true 3" system (not tapered at the downpipe). I'm loving that group A rally look of this exhaust. I need to have a good think about going for this system, as i'm still on the fence about upgrading to a new STI.
