Default Real Header/exhaust HP increase

I am having my LG headers with cats installed on tuesday with the Corsa Indies that arrived yesterday. What kind of REALISTIC HP gains will I see?? I had it dynoed last year on a Mustang Dyno and I hit 303 RWHP and 315 RWTQ with only an air filter change. I do plan on getting a dyno tune soon afterward, but was wondering what I could expect. Thanks in advance!

I can't wait to see your Dyno results! I am contemplating the exact same set up! I have Indies and have been asking similar questions. Most responses said 25 - 35 HP

Paul,

Lou Gilloti of L.G. Motorsports told me that 20 to 25 RWHP is realistic.

25 HP unless you also lean it out a lot.

Paul-
Let me know how it goes! I'm curious to see what it does after the install. Next time at Milan I'll get to see your taillights! I'm jealous your getting your car out so soon. I can't till April 1. Good luck. Jeff
