Downpipe question

[falloutboy]

I was wondering exactly how important an aftermarket downpipe really is. I recently had a new cat-back performance exhuast installed on my car, but I didn't do anything cat-forward, it's still stock. How much will a new downpipe help my car's performance?

Removing the cat will help more at this point than a DP on the T25.

Save the money for other mods first.
