I installed the Supercircuit headers today. They add a nice deeper tone to the exhaust. I still need to get the exhaust redone from the headers back; I've got all the new parts sitting here just need to get it over to the shop when I have time and they have a lift open. I've only driven a few miles to test out the new headers, and one thing I'm noticing is my rpm gauge says that I'm now sitting at 1100 rpm at idle even though it sounds and feels just the same when idling. No pulsing idle, just seems like it's reading high. My usual idle would be 500-600 rpm. Sidenote, if you're doing your own headers get power tools with deepwell sockets. It was a nightmare wrenching everything and trying to squeeze room in for breaker bars.
Car is a Mitsubishi Lancer 1.5L (4A91 engine), model of 2010.
No sport shocks are available from the title's manufacturers for it (like Bilstein B6 or KYB AGX), only the following ones:
ZF Group offers 3 brands: SACHS, BOGE and TRW with multiple options each, but I'm not sure about the differences each code has.
So which of the above is the most suitable for a sport driving style?
