been to greddy and dc sites.
dc - twin loop syle - says quite yet efficient and awesome sounding. i gather this means its not that loud but dont know what that means regards power.
normal catback- says designed 2 to make power and aggresive sound without being buzzy". i guess this means its loud but has good gains.
greddy evo - gives idea its not that loud but doesnt give much away about power gains.
man, the more ya look into this shit the more complex it gets.
anyway guys, keep the info comin especially pics and sound clips and dyno results.
