I plan on purchasing the Skunk2 cat-back exhaust and DC 4-2-1 header.
I already have CAI, so how much hp should I gain by adding these mods?
Also, does anyone know of where I can listen to a soundclip of the skunk2 exhaust?

 

The skunk2 is made by a company called Invidia, and like most canister-style exhausts, it is loud. To determine whether or not you like loud exhausts I suggest reading this thread: https://www.honda-acura.net/forums/s...ad.php?t=35132 (please don't post in it)

As for power gains, a typical GSR with bolt ons (intake, header, exhaust) makes a total of about 10 hp more than stock.

 

team-integra.net probably has a sound clip of it in the articles section
