Magnex for dummies question!

[172gal]

Hi

Just purchased myself a magnex rear box for my 172. Decided for the oval 6x4, not as keen on the twin pipe.

Anyways can anyone tell me the differences between a full system and just a rear box? i.e. sound? performance? etc.

Im not too clever when it comes to the mechanics of a motor. The guy in motorworld was pretty much clueless so couldnt tell me much!

Any help would be nice!

the back box is just that, the back box. teh system goes from the cat backwards.

A backbox will look nice and give a different tone. But a full system will give a different noise and you should get a freer revving engine as well.

Right think im understanding now

Cheers Chris!

If you had got the full CAT back system you would have been free of the dreaded 172 4k rattle and also you wouldnt get that annoying "tinging" sound when you stop/idle after a fast run. If doing a job why do it in halfs? The Magnex is a quality piece of kit and worth the money for a full system IMHO (2x3.5" CAT back owner).

Why cant see down the exhurst pipes. There seems to be a metal plate in the way going into the backbox.

Isnt that restrictive.

 

[telford_mike]

The gasses come around the side of the plate through a sort of grille. You can just see the grille on the left-hand pipe.

Mike when I seen your picture above you got me intrigued. So being a fellow anorak I just had too shoot up one of my 3.5" tailpipes (with the camera of course!). Result below;

The two tailpipes are joined by a "Y" pipe section leading into one silencing chamber, so is essentially straight through. Looks a bit different from yours mike, or maybe its just your camera angle? Are we sad gits or what? LOL

Yes.

OK mines coming to bits tonight, and Im going back to college to study Exhaust Technologies. THen I will be telford_mike CM (Dip) ET.

I have a nice Magnex sticker for my car, will post pics later

 

[paddymph]

nooooooooooooooooooooooooooooooooo!



stop all the anorakness!!!

A full system will take away a little low down torque (as there is less ack pressure, but improver top end BHP

i am thinking of getting a full magnex, which one should i go for? twin or single oval? and how noisy is it on the 172?? cos i would imagine it to be quite loud!! (which is a bad thing in my opinion) im more of a sporty tone kind of guy.

 

[telford_mike]

Its a sporty tone kind of zorst. Theyre quite boomy when new but they soon settle down.

I second my fellow zorst anoraks (Mike) comments re noise . They do get queiter after a few hundred miles or so. Just a slight tendancy to be boomy at 70 if on a climb or accelerating. Put it this way, I very rarely listen to my CDs these days.... the Magnex is music to the ears! It also helps to drown out the normal Reno rattles.

Mike, where is that picture of the Magnex sticker ...... you promised! Ill never get a good nights sleep until Ive seen it!

Peace & Power to the zorst anoraks ....... yo!
