Yeah... It would be nice to have for 20V too.. but the only way now is to DIY a transparent window.
Btw, try imagining how cool it would be to have a transparent valve cover as well... I think Lexan should be able to withstand the heat... but not too sure about it.
Any review on this? Heard someone said AT just nice with S-Flow setup compare to Straight Flow exhaust! Plan to install straight flow (HKS Silent Hi Power) with more 'garang' sound (EVO sound ). Mind to...
