JHH Posted July 30, 2005 Share Posted July 30, 2005 Got a 77 gl, does is have a catalitic converter or is that just a resinator? Plus for those who have modified their exhaust, what setup works/sounds best? Also has anyone here used nitorus on there subies? Quote Link to comment Share on other sites More sharing options...
SUBARU3 Posted July 30, 2005 Share Posted July 30, 2005 It is just a resonator. I have found stock is better that modifications and the stock exhausts usually outlast the car. Todd Quote Link to comment Share on other sites More sharing options...
eyesore Posted August 20, 2005 Share Posted August 20, 2005 I removed my resonator and added a glasspack & side dump exhaust. Sounds wicked, and it actually improved responsiveness, and top end. The stock system really is pretty restrictive on these. (or maybe my stock muffler was plugged?) It's been going 4 years strong till recently when the stock y-pipe cracked.
