Varex Muffler.

[MR 33]

You'll have to weld some flanges on to fit it.

And yeah it doesn't get that quiet by making power! Puts out a crazy rasp at high revs. Still a well designed muffler though so not TOO restrictive.

I really paranoid about driving with it closed. So I just take it nice and easy.

yea, so after say a year. the flange will have carbon build up.

so if the butterfly valve gains a bit of carbon, even with it open, it will still restrict the exhaust.

so a 3'' will be basicaly 2.50. this is my problem. have been thinking about this problem for a while.

a clear exhaust =loud

an impaired exhaust= quiet but restrictive :S

forgive my ignorance, is this item flanged?

incase i wanted to go back to my zetti muffler??

edit: is there any backpressure problems when diverting the gas flow thru a 1'' hole!!!!!!!!!

Yep, flanged.

Not sure what you mean with 1" hole - or do you mean when the valve is closed? If the latter then you simply go easy when it's closed, if you want to put the foot down - then open it to full.

[r33cruiser]

indeed. when the flap is closed, the exhaust gas is diverted thru a tiny hole.

OK...

I have my Varex fitted. Previously I had an Xforce cannon muffler (and resonator that was freaking me out due to it's close proximity to the ground), now fitted with a hot dog style resonator.

My first impressions are that overall, the Varex is quieter than my old cannon, even when wide open... but I've lost that horrible drone which was driving me nuts (yay).

I also went for the oval version with twin tips - this normally retails around $500 but I got it for $400 (long story

Performance affected?

Well, hard to tell after just the trip home from the exhaust shop... although I did do a semi-serious acceleration test from a standing start through to about 140km/h on a (mostly) lonely bit of highway - and it felt mostly the same as before. Might be a slight loss... hard to tell for sure until I get out there and try it again when it's all quiet. I suspect the turbo is spooling up a little higher in the rev range but again I'm not 100% sure yet.

One thing is for sure - it looks practically the same as the factory muffler and shouldnt get the cops all excited like the cannon did.

When set to quiet - it is damned quiet all right! In fact, all I can really hear is induction roar.

We spliced the wiring into the rear wiper power feed, so no need to run it to the bloody ciggie lighter...

Anyway, here is a quickie video I did which might help give you all a better idea of what it looks and sounds like. the first bit shows the old Xforce cannon muffler: http://au.youtube.com/watch?v=autQyxmR8N4

I might do a better video later on, as this video doesnt show the valve operating, or really show off the new muffler from all angles.

just saw it.....very impressed atm

[br3ndan]

wow a big difference... you can really hear the low end deep "bass" per say disappering when its closed up!

If i didnt have my HKS Silent Hipower i would get this one for sure.. =)

[R334door(s2)]

[KezR33]

i woudlnt mind one of these if they came in 4" inlet

XForce have been saying the 3.5" versions are "coming"... although they've been "coming" for ages now.

I'll probably buy one when they eventually release them, and put my current on onto the Suby.

4" is kind of HUGE, isn't it?

I was originally keen on the APEXi PS Revolution muffler... until I found out the retail price: $1700!

[MyStag260]

Unreal thread guys, was looking for some more real world info on these things and bang there it is Think i might wait for the 3.5" version as well.

Great vids as well thanks guys

Cheers

Definately getting one of the twin tip ones. my ex has one of the cannon ones on her 33. sounds as quiet if not quieter than stock exhaust when the valve is closed and nice clean louder note when open and you dont get that annoying drone on the highway either.

I wouldnt hold my breath for the 3.5" version.

Theyve been saying theyre 'gunna' produce the 3.5" version for a long, long, long time now... I've no idea why this is so, you'd think it'd be a simple thing to do given all their other products and facilities.

[kevzilla]

i still cant find the twin tip version anywhere.... any pointers? ebay only has the single tip

Contact Xforce themselves, or one of the listed retailers on their site.
