or are there better combos out there? Is it worth it?

I had both the Greddy header and EVO exhaust. I paid full price for the header (440) and got a deal on the exhaust (250). The exhaust was well worth what I paid, it had a nice tone to it and was solid. The header was ok, looked nice and gave small gains but not worth what I paid. Unless you are trying to squeeze out every ounce of HP out of the 2.0L I would just keep the stock manifold on. The exhaust I would buy again.

I agree. I have the Greddy header and SP exhaust. Sounds great. But unless you're staying NA I would skip on the expensive header.
