To buy headers or not?

Personally, I want the short ones, because it is easy to pass the registration test every year we do. However, I have read a lot about Z1 short headers, and how effective they are. So, now my question is, is it really worth it to go for short headers with test pipes I have with catback or no, it is not worth it? In other way, am I getting with z1 short headers 10+ whp or no?

Many thanks for sharing your experiences. Highly appreciated.

Stop at the easy bolt ons and then decide whether you wanto REALLY commit to NA or turbo



and if your goal is learning how to drive on the track, the money is better spent on seat time (hell, better spent on a helmet)
