Gents,
I'm on the market for getting a good uel+ over pipe for my 23 BRZ ... I know it's new engine, and just looking for best option to get hp gain (I know EL is higher gain, but I love to keep the boxer rumble) so I just need your opinion for best uel for my target, keeping in mind that my setup with my BRZ will be only ( uel+ op+ tune ) and will be kept that way for long time with stock catback as I want to keep low noise level
