Ka exhaust on rb20det

[jdmser]

I know it will bolt up with the stock down pipe, but will the Ka exhaust have any harmful effects on anything else? Like the turbo.

It will not hurt anything, you just will not get the full power from the turbo!!!!

stock 240 exhaust on my RB25 was laughable. you could barely hear the engine, but it ran fine.If you are going to keep the stock exhaust for a while, I would at least recommend getting a high flow Cat. You wouldn't want your cat clogging up and causing issues with your new motor.

i went with the Apexi N1 Dual from horsepowerfreaks.com and a high flow Cat. much better sound, much better performance.
