    I don't think the GSR has a stock resonator, but I wrecked mine a couple years ago so I can't remember for sure. Here's my suggestion for a good sounding & free flowing exhaust.. buy the Megan headers they're a decent set & copy of DC, and if they don't have a 2.5" collector (I can't remember) have a muffler shop cut the collector off of it and weld on a 2.5" collector. Buy a magnaflow cat that is 2.5" inches inlet to outlet and run a 2.5" catback exhaust. If you need it quieter you can always add a 2.5" resonator there is plenty of room in the DC2 exhaust to put a good 18" or so resonator in there. If you go smaller you're going to be choking off the exhaust and hurting power.. any questions send me a PM I had a GSR for many years.

    so i should be ok with how loud it is with no resonator... i got the magnaflow cat...... and im thinking of letting the muffler shop just putting 2.25 pipping after the cat......? and putting a stock looking tip.

    What size is your magnaflow cat? To optimize your exhaust flow you should match the header's collector size to the cat so you don't have a restriction there. 2.25 should be just fine.. as far as a muffler you might want to look in to Magnaflow. They are relatively inexpensive and still high flowing, and they don't sound like a can of bees when you're driving around :D

    2.25" should be good for NA. Otherwise, use 2.5" for turbo setup. Get Megan, I heard it is cheap, but quality is good too.

    A test pipe vs. a high flow cat makes maybe 1-2 hp at best while polluting the environment so :nutkick: for doing something like that.

    Did you check for ECU codes? Hopefully it threw a code when it died and that will point you in the right direction.

    are you using a scanner? Try jumping the service connector in the passenger side kick panel area and count the check engine light flashes..

    The beeping sounds rather odd.. but it looks like it didn't throw a code. Sorry I'm not sure about the screws on the igniter it's been a long time since I had my Teg unless you have a picture. It's probably an igniter or coil, but could also be your cap & rotor depending on how long it's been in there. My GSR died while driving it once and it turned out to be the cap & rotor wasn't delivering enough current to get the plug to spark.

    run a stock s2k axle back for the exhaust with the 2.25 midpipe and the dc headers..it will open up more but be quiet enough as well

    It won't fit on a DC2 chassis and you can make the same design with aftermarket parts.

    You realize an S2000 uses a dual muffler exhaust, right? I very much doubt that it would fit on his Integra without running some crazy custom mid-pipe, plus custom hangers to hang the mufflers.

    Honestly I think it would look gay and be retarded. He can have a custom exhaust built that's quiet and performs decently for a lot less money.
