Hello.
I have been searching on what kind of exhaust system to do to my 2004 eclipse GTS. I am considering doing straight pipe since it sounds pretty dang sweet. If I was going to do that should I just cut the muffler off and run straight from cat out or, cut the cat out as well. Any input is helpful

You're referring to my video I put on YouTube a few years ago. The exhaust was simply just cutting off the stock muffler and using a piece of pipe with a tip on it. Keeping the Stock Cat's is going to keep the sound nice and mellow. Costs maybe $30.

after meeting up with some kids at my campus who have done the same thing it is not that loud at all. It is deep and mellow. of course its loud when you step on it to show some ricer civic whats up. But what after market exhaust isn't loud when you floor it?? O and by the way my fiancés father loves the idea so suck it :p

I have a cold air intake on it now. Going to pull a 74 manifold and do that swap next week, and for Christmas going to get 2 borla mufflers to put on my dual exhaust.... No I am not a ricer! Just can't spend money like crazy all at once while I am a full time student and living with my fiancé.

3" Tip Muffler Catback Cat Back Exhaust 95 99 Mit Eclipse GST Talon Turbo 4G63T | eBay

Notice the huge resonator. I've put these on a number of cars, only thing I would say is be prepared to lengthen or shorten it. The same system fit a GT cali spec but not GTS so I'm not sure where the variance came from but be prepared.

If you're worried though an easy way is to cut the main cat out and cut a length out of the front piece of the old catback. Use the flange from the old catback to bolt to the new catback and clamp the other end to the back of the Y pipe in place of the main cat. Gives you the adjustment you need. It's about as cheap and nig/rigged as it gets but for those in search of cheap sound it works and still sounds better than any $500+ aftermarket bullshit catback.
