There’s nothing like some good ol’ high flow. 
This delivers a few extra HP & better emissions.

It wasn’t too hard of an install, but I do recommend having the following on hand prior to the installation: It took about 2 hours total for the installation.
1. Good penetrating oil. 13 year old stock exhaust systems have very tight nuts.
2. Breaker bar, ratchet, 14mm socket, some extenstions and a closed 14mm wrench.
3. A floor jack and jack stands. Mechanix gloves, Eye protectants such as goggles.

Disclaimer: This is not meant as a complete installation guide. Please refer to a good Honda repair manual such as
“Helm”. Also, be aware that anytime you work under a car it can be very dangerous. please take the proper safety precautions! Always use proper jack stands. Last don’t blame me for any installation you do as I’m just an amateur like the rest of you out there, so install at your own risk ;o)
