Full Magnex System

[flyfisher 6 2 Cars]

time has come to replace the standard system on my 1.9 gti. ive been offered a full magnex stainless steel system including four branch manifold apart from the obvious i.e. lasts a lot longer could i expect any power gains over standard system and are they any good

[Cameron 16]

You could expect a couple of bhp.

we have one on our 205, sounds nice however ours has a small blow of which I can't locate, its mainly heard when you start to apply the throttle and sounds like its near the manifold. Where do these break (as I've heard they do) or where abouts are their weak points?

[Cameron 16]

At an educated guess, it's a cracked weld at either the primary to flange joint, or the primary to collector joint. Most likely the first one though.

[MrG 3]

in other words a pain to repair whilst on the car?

[Cameron 16]

Ooo.. yeah probably!

I had a full Magnex system on my 309 8v with a K&N 57i induction kit and otherwise standard and the bhp gain may have been small but the mid range torque was definitely improved. Hard to say if it was worth the cash as i paid full price but as a fit and forget alternative to a standard system and if the price is affordable i'd say go for it.
