August 28, 200322 yr 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:
August 28, 200322 yr 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
August 28, 200322 yr Author 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
August 28, 200322 yr 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
