The inlet diameter is too small on the muffler (2.17") so i was wondering if an exhaust could correct it to 2.5" or even 3"?

I am sure they can but don't really see the point. With such a small inlet it is likely to have relatively restricted internal flow as well.

You'd be better off finding a rear muffler that is the correct size for your existing piping. Try the SAU classifieds, Firesport, Hardtuned, Gumtree or do another search on Ebay and I'm sure you'll find one that fits.

Thanks.

For that price its really not worth the effort.

As mentioned above, you would be better off buying the correct sized muffler for your application, locally.

i got a 2.5" oval muffler from my local exhaust shop for $120 including fitting.

as for getting the muffler altered, yes they could flare out the pipe to make it bigger, but i bet the internal diameter is still only about 2" so it would be a restriction. a stock muffler would probably flow better

    • Just checking, when we are talking about high temp fluid, are we all referring to DOT 5.1? I haven't had any issues with changing it every 2-3 years. 
    • Yeah that is still true AFAIK.....good brake fluid should be changed annually because it absorbs water faster which is more often than most mechanics would do it. There are cheap tools that check water% in brake fluid if you all scientific about it. I for sure would (do) run good brake fluid in anything that even casually saw the track like Murray said; avoiding the risk of "exciting" fade is worth it
    • Well, back in the day..... "race" fluids, which were essentially only really "high temp" fluids, used to absorb water more readily. So they really needed to be changed more often anyway. The coincidence of that being directly necessary along with it being what racers would do as a matter of course was just fine.
    • Does the high temp fluid degrade any different over time compared to normal one? That's one thing I've always been wondering. Because a track car is going to get the fluid flushed probably way more often than every two years and will see less kilometers driven. I would think the requirements are different. I'm running Motul RBF 600 in mine. Was recommended by my mechanic before a trackday and I've stuck with it since. Hasn't seen the track since but I've kept buying and using it for servicing anyway.
    • The brakes are all stock bar some DBA slotted discs and the EBC pads and braided lines. The car has brake ducts as standard but they're kinda pointed in the general direction of the brakes rather than really getting at the heat source. I guess I should hit it with an infra red thermometer after a session and see what they're at.  100%! Its just a curiosity more than anything. As I said, high temp brake fluid was such a track day rage back in the day. From people I speak to at the track and threads on here everybody has their own take on it but I'm not gonna scoff at spending a few more bucks.    OH, a quick side question - would you use brake fluid from an opened container even if the lid has been on? Eg, if you have a bottle that you opened last time you flushed, it's been tightly closed, is it still good?
