Apexi N1 Question

[Klark21]

If I purchase the Apexi N1 Exhaust System, will I need to purchse the downpipe also???

You dont HAVE to, but it is recommended. You can purchase just the catback system. But let me tell you, replacing the Downpipe is one of the single most noticable upgrades to our cars. (Besides a bigger turbo or anything of that nature). At least that was my experience.

If you replace the downpipe and still want to run a cat, the only two set-ups I know of are the RRE downpipe and their cat, and Extreme Motorsports and their cat, right? Are those the only two options with a cat?

Also, if you replace the downpipe, eliminate the cat, and keep the stock turbo and O2 housing, would you get boost creep?
