What do you guys think about this cat-back?
Click me!
I like the look of it, reminds me alot of the APEXi world sport exhaust system. I only have two concerns with it though: 1)sound, and 2)it says 2.5" piping, but the piping pictured looks more like the 2.25" that most cat backs come with, so I'm wondering if it really is that big or if it just a typo.

2.5 inch diameter!!! That's unseen...i wonder how it will effect the low-end?[hr]

the comptech on my dad's rsx-s is 2.5", larger in order to match the increased displacement. 2.5 would be a bit overboard for our cars, and you might end up losing quite a bit of horsepower in the low end. An eclipse running a 3" exhaust better be running fairly high boost, otherwise that is a waste too.... most people running big turbines really need to open up their cat back, the turbo produces enough backpressure on its own.....
That big of an exhaust might sound nice but it will affect flow. Since the air will be expanding, it will cool and get denser, it will then slow down the velcocity from the expanded piping and cooler air. Hotter air moves faster throught the pipe as well as the right size piping, like a water hose being pinched. So you lose either way. Now the higher flow muffler will add some horses, but might balance out with the larger diameter piping.
You will definitley lose low end because of lack of flow. Get something more reasonable, unless you add 4 more cylinders or turbo or alot of mods.
Of course, if you don't care about power and just want that sound, it's totally up to you.

2.5 on a civic, christ. I drive a Dodge Cummins TD with a Banks upgrade with a 5 inch exhaust. Diameter depends on application

You don't want to sound like a complete fool, driving a civic with such big piping! that is sort of ricy!!!! i dunno thats my opinion, i have 2" piping on my exhaust and it is just louder than stock, but my engine is still louder, so until i get my intake it won't be as loud, you don't just want the sound do you? well then again our little civic's aren't going to get tons of power until a turbo is dropped in the engine!
Don't go as big as 2.5!!!! stay a bit smaller!
blahhhhh
