Great power gain and Great sound.
I was shocked when I revved up the engine after the install. The sound was amazing and more than I expected. And I could feel the power gain the first time I drove it. Much quicker in the lower rpm's and a big gain when VTEC kicks in. The header was easy to install for me because I have done header installs before. But I would still say do the install yourself if you have the tools for it. Hardest part of it was getting the old bolts off the flange after the catylitic converter. I ended up having to drop the exhaust so I could cut the bolts off. Header comes with new bolts and gasket for this section so no problem there. The fitment was perfect and very easy to slide it up into position from under the car. It also bolts right up to the stock exhaust which I have on for the time being. Overall exremely happy I chose this header and I would reccomend it to anyone looking to upgrade their stock header.
Pros: Great Sound,Easy To Install,Durable,Attractive Design.
