Which exhaust system should I get?

I m planning to purchase the RS-R Exhaust Systems EX-Mag or the Greddy SP2 Exhaust System, but don't know which one I should buy. They both have a low exhaust tone and isn't ricer sounding. The RS-R looks like the stock Integra exhaust while the SP2 looks kind of ricer. Which well improve my car's performance more: horsepower wise? So which one should I get?

regardless of which one you get the hp gains will in all probabilty be about the same (not much), personally I'd say of the two the rs-r.

He's right, the HP won't be that much of a difference. The Greddy muffler is pure SS while the RS-R tip is only SS with the rest with some kind of grey coating which I personally think looks dull. In terms of looks go for the Greddy.

yea, i agree... i've heard nothing but good things when it comes to the GReddy exhaust.

i'd go with the rsr I have the same system on my G2 and i love it. I have heard nothing but good about the exmag, and i have heard many mixed feelings about the greddy. I researched these exhausts for about a year before i finally chose the exmag... and i couldn't be happier.

my buddy has an hks super drager on his and it sounds really clean............ flowmasters sixty series sounds extremely nice on a teggy.......http://www.flowmastermufflers.com/cgi-bin/flowmaster/vids10.html
