ScoobySchmitty Posted August 28, 2003 Share Posted August 28, 2003 Ok, probably a really st00pid question, but I'll ask it anyway. I have a 91 legacy, with a regular exhaust, 2" off the catalyst. I would like to put on a more tuned muffler, however I cannot find a tuned muffler that has a 2" inlet. PLENTY of 2.5" mufflers of course. :madder: Anyway, would it be ok just to install a 2.5" inlet muffler with an I/O fitting to match the 2" pipe off my catalyst, or should I just go to a muffler shop and have them install all new piping from the catalyst back? Let me know what you think! ScoobySchmitty:headbang: Link to comment Share on other sites More sharing options...
MilesFox Posted August 28, 2003 Share Posted August 28, 2003 if you dont have emissions regulations in your state, go with a custom job(no cat) tell the muffler shop its an "off-road" application Link to comment Share on other sites More sharing options...
ScoobySchmitty Posted August 28, 2003 Author Share Posted August 28, 2003 An interesting idea. My only concern would be the O^2 sensor on the cat. I'm getting a Cosmo Racing cone filter soon. Maybe I'll just go straight pipe like a friend did on her Blazer! Thanks! ScoobySchmitty Link to comment Share on other sites More sharing options...
Subie Gal Posted August 28, 2003 Share Posted August 28, 2003 on both my impreza (2001) and on my 99 Legacy I had a custom 2.5" mid pipe made at an exhaust tuner's shop.... this was cat-back - kept me emissions friendly and it only cost me $100 installed. nearly any muffler (back box) you desire can be made to fit... good luck to you Jamie Link to comment Share on other sites More sharing options...
