I am installing KOOKS longtubes, OR/X and either the SLP loudmouth I or II exhaust. The car is not a daily driver and looking for a very loud exhaust set up. Which of the two loudmouths would sound better? I am not worrired about volume, just as long as it sounds good. I currently have the dynomax 3" catback but have never really been happy with it. Any help would be appreciated.
