Great Exhaust.

Exhaust is great. Quality and appearance is great, but you pay for it. Sounds good, but I don't get any noticeable power increase. Magnaflow should have made this exhaust go all the way up to the catalytic converters. I think the factory y-pipe still constricts the exhaust too much.

Well worth the money

Had this installed on my civic SI at a local muffler shop because they had to do some modifications so it would fit with my aftermarket bodykit. I LOVE the way it sounds when I turn the car on. When the car is stopped at a light you barely hear it until you step on the gas. But be warned.... You will make people turn around and see what's driving down the street. The sound is rich and deep and not tinny. Overall very happy plus I feel more hp than stock. Thanks to Autoanything for the suberb customer service!

Awesome craftsmanship, appearance and sound. It was fairy easy to install once the stock exhaust was removed; excellent fitment too. The toughest part for me was removing the stock exhaust. My Si is 6yrs old so rusted bolts/nuts was an issue especially where the pipe connects to catalytic converter. So be prepared for rust if you have an older vehicle like my; you will need some penetrating lube and maybe an "easy out" or "bolt out" socket if the bolts/nuts are stubborn. Once the stock exhaust was removed, install was pretty straight forward and took me only about 30 minutes to install the Magnaflow exhaust system. Here's a tip: this particular kit doesn't come with a gasket that seals the exhaust to the catalytic converter so make sure you pick this gasket up from NAPA or your local Honda parts before you start. For a 2002 Si, this gasket is a metal ring. My only concern with the system is the seal at the catalytic converter; it's not a perfect seal like the stock but it might as simple as me having to retightening the nuts. Overall, I'm extremely happy with this exhaust system!
