    Icon12 I have a dilemma regarding the BX

    Well the story starts a couple of years back when some new neighbours moved in. They had small kids and at that stage I used to arrive home in the middle of the night most nights. So I was advised by mum ( ) too put a middle muffler onto the BX. Well the neighbours moved in and guess what?
    The dad has a big shiney Harley
    Now in the last week or so the said middle muffler has disintegrated inside and is making horrible metal vibrating noises.
    So my problem is- Do I:

    A) Remove the muffler and get some nice 2.25" pipe all the way to the rear muffler

    OR

    Advertisement


    B) Get a new middle muffler

    My partner has a nice quiet 306 that we use for highway trips and holidaying and the noise has never bothered me in the past.
    So come on guys should the GT sound like a GT or a grampa mobile?

    With the intensification of policing on Queensland roads, I'd say stick with the muffler...

    I dunno, mines always been quiet, and I like it that way, but if i was ever on the exterior of the car it would be another matter...

    Shape/dimensions look exactly the same as the original.
    The exhaust is fine and in good condition, just the crappy middle muffler has died.

    You'd probably need to talk to someone that knows exhausts (possibly post this in the technical section).

    If you remove the middle muffler, you might kill the flow rate of the exhaust, so loose a lot of torque down low, however you'll be able to hear your lost power quite loudly. If it's down properly though you might even gain something.

    Try to change the subject of this to 'exhaust flow rates' or something so the knowledgable people will answer.

    As for the neighbours, I've never given them a second thought ...... ever ..... If they couldn't put up with noisy exhaust, bugger them. After all you will gently roll in, not scream up the road pulling 7000rpm (I assume you will anyway).

    Shane the car doesn't come with a middle muffler as standard. So if anything IT is stuffing up the standard flow characteristics.

    I don't think the neighbours will really mind. Thanks for the help guys.

    I've got no idea what your issue is then BX's aren't *that* loud. If it was to loud it'd be an annoying [email protected] of a thing to drive anyway. I'd just chuck the muffler away.

    I can't really remember how loud is used to be without the muffler. I did drive it for a couple of years like that so i can't be that bad. I might just get it taken off then.
    Just need to moderate the loudness with the right foot then.

    Hows the CX Turbo going shane? Is it going to the next cit in? I wouldn't mind heading down to dubbo (isn't it?) next year.

    She's going well. I've sorted most of the electrical issue that came to ahead not long after I purchased the car (though the injection computer dying certainly dropped a spanner in the works).

    I plan to finish all the mechanical stuff before August when the BX's rego is next due.

    --ie: rebuild front right suspension ie: ball joints/bushes/bearings (having already done both rear arms, and the front left suspension)
    --sort out the radiator that's decided to start leaking coolant
    --lubricate the radiator fan bearings/bushes that are getting noisy
    --Finish replacing them terminals in the big multi-plugs behind the motor (to ensure continued reliability).
    --replace the lower engine mount.

    All my issues have no doubt been due to the injection computer slowly going intermittant then stopping It took me quite a while to convince myself that **yes** it really was that computer that was the problem (bloody bosch computers ).

    Yep, we'll be heading to Dubbo, just watch for the CX Turbo pulling a 17' caravan behind it ... Possibly I might try to join the 50year anniversary for the DS as a support vehicle later this year. That should be a lot of fun.

    Well Dave, I'd have to say that I think you should keep the middle muffler seeing as I live in the same house as you. At least after you had the oroginal middle muffler fitted (at our expense I seem to remember), the windows didn't rattle quite so much when you went up the drive beside the house. Perhaps you could even get a bigger middle muffler so the windows stop rattling completely!
