Magnex Cat-back System. Anyone have it?

[318ti_Portugal]

halek, I think the exhaust is very nice! It looks very sporty and not ricey at all! I think it just needs the said tweeking to be perfect! Once again, thank you for the pictures! Really helpfull! Just another request... Any chance of a video to hear the sound of the magnex?

me old man went down there with his mates & rode it this summer on his blackbird (CBR1100), brought me back the sticker. I'd love to do it myself,you can just turn up, bung em some euro's & do a lap in whatever you turn up in.

yeah ive seen it on the tv. its about 20 euros a lap, and would take about 16 mins in a Stock TI.

we can then put all that info in a knowledge base article

looks good, btw!

got me some scales & pulled the magnex off to give it a tweak & make it fit a little better so I weighed em both (cat back only)

stock = 35.6 lb or 18.3 kg

magnex = 20.6 lb or 9.4 kg

that stock pipe sure is a heavy mofo

Excellent weight on the magnex! Half of stock!

Halek, have you tried raising the muffler? Does it have clerance to be raised? Like cutting a section of the hangers and welding them a bit shorter?

I've got it as high as it will physically go now thanks to one of L8's old posts that cali pointed me toward (thx guys).

The pipe rubs the rear cross member when you lift the rear box higher.The stock pipe is flattened on this section to give it clearance,so I marked the pipe up while fitted to the car, removed it & slightly flattened it using blocks of wood & a club hammer to resemble the stock pipe. I also noticed that one of the rear anti-roll bar fixing bolts was about 3/8" longer than necessary & was fouling the rear edge of the magnex silencer, so I took about a 1/4" off the end of that while in situ with a dremel. I also put a 1/4" deep crease along the top rear edge of the silencer to give more clearance from the anti-roll bar. I know it sounds a bit savage whacking a new exhaust about with a club hammer but if your careful & use suitably sized pieces of wood between the pipe & hammer blows you can make it look like it was made that way.

Now your clearance issues are solved all you need are some shorter exhaust hanger rubbers. BMW Mini cooper S rubbers work perfectly - see pic, black is the standard hanger & red are the mini ones (part# 18 20 7 535 665)



here's the result, ideally I'd like it another ½" higher but it wont go any more without fouling the anti-roll bar. Still, I can live with it like this

actually, that first calculation is off which one did you weigh it in, pounds or kilograms?

EDIT: it certainly looks better after your adjustments good work d00d.

opps, my bad

should be 35.6 lb or 16.15 kg for the stock pipe

[318ti_Portugal]

Excellent work! With the mini-hangers it really looks great!!

Are you happy sound-wise?

It sounds excellent, if anything a little on the loud side for my taste (I am a bit of a perfectionist) but in no way is it intrusive. Stomos reacons they mellow out within a few hundred miles & mine has only done around 50-60 miles so I expect it to be near on perfect once its run in.

[318ti_Portugal]

Any chance of a video? I would really like to ear a magnex. I just can't make up my mind, exhaust wise...

[davep-uk]

yeah, i'd be interested to hear another one cos i'm starting to think mine was not sealed properly.

[318ti_Portugal]

davep-uk, is yours loud?
Can you post a video? Or maybe some pictures?

I just can't make my mind between the magnex and the supersprint.
The magnex is stainless steel, lighter and probably louder and cheaper.
The supersprint has better fitting on the Mtec bumper because of the square tip.

[davep-uk]

I'LL try and post some pics in the next few days. the magnex does not fit straighyt on my car as i do not have the Mtech rear bumper. so it sits to one side. it is not too loud, just a nice grumble at hard accelaration. but i dont think mine was sealed properly when it was fitted as it sounds a bit "blowy". i need to get it up on ramps to have a proper look.
