Are whisper lids easy to self install and how much horsepower do you gain? I'm gettin 2.5 catback. Is the whisper lid going to affect the sound?

You'll gain 5-10 bhp with a whisper lid max on a stock engine, works better with exhaust of course, and its extremely simple to install [img]smile.gif[/img]
If you can change your air filter, you can swap in a whisper lid, and its worth doing if you want a good first mod for performance.2002 5-spd NBM Camaro

Whisper is so simple even I can do it. Makes your engine sound better also.I solemnly swear I am up to no good.
