Are Mongoose stainless steel exhausts any good and has anyone had good or bad experiences with them?
Cheers

i have had 2 of them and the first fitted no problem but the second one was miles off and hung down too far under the car and would have been destroyed the first time i drove the car.

the general thoughts on them is that there crap.

very loud aswell.

thay are hit and miss with regards to fitting properly and they are stupidly loud.

Heard very bad reports on the fitting of them. Mongoose also have a reputation for being boomy

Well, that's me out of the running for another stainless then. The Scorpion was too loud for my liking - inspite of several people assuring me that it "wouldn't be much louder than standard if you keep the standard front box."!

not tryed mongoose but i have a supersprint rear box very impressed with it

Very interesting debate / comments and so far the Mongoose gets a thumbs down i think from the Zoners

How about Sebring?

remus anyone? when that wore in LOUD

Hiya. Had a terrible Sebring on a 16V Mk2 golf. It was a terrible fit and fell apart in no time.

Is this for your 320 convertible? Surely a factory system would be nicer as yours is such an original car? If you want a bigger bore go for a full 325 system. You might have to change the manifold as well though. Not too sure. I know the mainfold to downpipe gasket is different on a 2.0 to a 2.5.

I had a Mongoose (briefly) that was a terrible fit. What was worse was the shocking attitude of the manufacturer about the whole thing, basically, it was not their problem. Avoid like the plague.

Hi Trevor, yes your right about wanting to kep my cab pretty much original, i was just testing the waters but i think with all the comments so far about non BMW exhausts it might be well be best to go for a factory system like you say. Dont like the sound of having to change the manifold though - sounds expensive!

Cheers for all the comments so far - keep them coming.

325 system will fit straight onto a 320 one peice manifold, i have done this on my touring.

get a powerflow from rsr

Right, here we go yet again.
If the 320i in question has the later twin-pipe-all-the-way-through system on, either of the 325i systems (2- or 3-piece) will fit straight on the manifold.
The only difference between these systems is that the tail pipes are a bigger bore on the 325i system. Everything else is identical.
You only need to change the manifold if the 320i system is the earlier type - single pipe from the centre box back.

I will watch this with interest too. I fancy a stainless for mine (prob just a back box), but don't want burst ear drums. Ive heard good things about Supersprint? i.e. Good quality and not offensively loud.

Although I am also aware that many stainless exhausts will possibly be a bit loud and boomy from new until they coke up. I had this experience with a Powerflow item on my old Seat Ibiza.

Still not the whole story; there were 2 different sizes of manifold flange available on the 325i, which means that all 325i systems will not bolt up to all 325i manifolds, let alone all 320i manifolds. This change was not made at the same time as the swap from 3 -> 2 piece, so you need to measure the flanges to find out if things'll work.

The above is definitely the case, but IIRC there's also another 325i manifold with a totally different type of flange (maybe 2 flanges) - but I've never had one of those so can't remember for sure!

There's a full Magnex SS on one of mine - very quiet, almost like a standard exhaust, just a nice note when the revs are high.
