    Resonator Delete - X Pipe Necessary?

    Guest-only advertisement. Register or Log In now!
    Hey everyone, so I am thinking of doing the secondary (big) resonator delete

    I see that everyone does the X-Pipe thing

    I have a shop that will just do two straight pipes instead for like $200 fully installed

    Will doing a straight pipe hurt performance as opposed to the X-Pipe? What's the point of the X-Pipe?

    Well you should also look into your states paws refueling resonators, as the x pipe counts as a resonator. Plus it keeps the drone down.

    I don't have to go into emissions where I live fortunately

    Just looking for the best sound

    The stock exhaust is basically silent



    I just want a sound more consistent with the horsepower without having a jack ass exhaust

    Does anyone have recommendations to accomplish this? With a setup they have actually tried?

    Also looking to go the cheap route here

    If youíre in the US all vehicles require a resonator itís for your state inspection. There are several topics about exhaust in here wit set ups consistent with what youíre looking for

    Is it better to do a muffler delete or a resonator delete?

    There's not really any exhaust options for this c6

    Are those inspections the emissions inspections?

    Because I don't have to do those in my area for cars newer than 2009

    Huh I guess resonator delete is what gives drone I guess I didn't know that


    So perhaps muffler delete is the way to go?

    Nick, I think what he is saying that even for state safety inspections that there are required items that have to be present on the car and the resonator is one of them. I have no idea but that's what I think he is saying.

    Exactly, technically, both muffler and resonators must be present on all vehicles, a resonated X pipe does count as a resonator.if you donít have those items, your car wonít pass inspection, and will not be road legal after the date on your sticker runs out. I work for a shop in Rhode Island and honesty states are getting very strict on exhausts

    As for drone, removing anything will add drone. Your best bet would be cutting out one set of resonators and putting in the x pipe, and a set of mufflers. That would give it the sound consistency your looking for.

    I have never gone to one of those lol maybe I am just an idiot or something I have never heard of that

    Okay regardless of the inspections maybe we will have to X that X-Pipe idea

    What about mufflers can I just swap out the current mufflers with something else will that have good results?

    Well I don't want to touch anything that will make my car unroad worthy because it's not worth the time and headache for me to get it reinstalled every year for the test

    I am going to double check on those safety inspections but does anyone know anecdotally if Washington state has these?

    Damn I am getting the feeling I have to just leave this thing stock if I want to make the smart choice

    I just wish it had a little more growl like a v8 - the sound is so unsatisfying and makes the speed not really that apparent

    Swapping new mufflers in should not be a problem. I was just trying to give you a heads up about US inspection laws. And by shop I mean just a mechanic shop that does state inspections. Just remember that youíre putting parts on an Audi, donít cheap out, and youíll get great results.

    To my knowledge in WA there are no visual inspections for passenger cars. Iíve had multiple Audiís with exhaust modifications and since youíre not touching the emissions system youíll be fine.

    If your getting rid of all the mufflers and resonators (6 total i believe, two baby front resonators, 2 center mufflers, and 2 rear mufflers), you can youtube B8 S4 straight pipe and that should sound similar. You'll have a super loud car but with alot of rasp. When I had my remus mufflers w/ the center mufflers removed (kept 2 front baby resonators), it was loud but the rasp and drone was unbearable.

    But if you just want to be loud just straight pipe it. If its too loud or raspy, just add a muffler or small resonators to quiet it down.
