anyone heard of a heisman exhaust system?? a bmw mechanic got one through a bmw store, cam with a very small ding in it and got it for cheap. is this a high quality brand??? full stainles, polishes crome tips, dual 3 inch.

u sure its heisman and not eisenmann ?

Spelling mistake i'm sure. They are fantastic systems. I was offered a system for the Rieger, but even with a huge discount, it was still fat dollar, so i'd snap it up if you're being offered it cheap

sounds german.

It is. I think Sal (M5 Pilot can supply them)

There is eisenman stainless back boxes in the zone shop, although they are wildly over priced I think. OK, it's a good company, but I got exactly the same style, with 3inch slash cut twin tailpipes, going out to the side - looks great on the sport models, custom made from London Stainless Exhaust Centre in Guildford for Ԛ£200 plus vat & delivery - total cost Ԛ£247. Beautiful piece of kit. Also, there was no welding required, straight on no probs.

Same style as the eisenman, but theres a reason why the eisenman is costly, you get what you pay for.

I appreciate that, but also, the most expensive item isn't always the better for it. The back box I purchased looks exactly the same as the z.shop exhaust. It's made of good quality stainless steel, fitted like a glove to my standard middle box, body straps & exit within back vallance, doesn't sound lairy loud, but subtley so. I could have got them to adjust the sound to be, say, lairy loud if I wished. But I prefer a big sound done more discreetly, like BM factory would do themselves. I wouldn't be surprised if performance has improved, albeit no doubt by a tiny amount if any, considering this isn't in conjunction with any other mods, breathing and the like. I'd be interested what would you say could be the difference between the two exhausts Craig?

Cheers, Paul

if they can adjust the sound then it can't be good. the eisenman exhaust will be rolling road tuned for the car it's for. Whic can only be a good thing. Also i expect the outside is well built but what are baffles made with? most are made with mild steel on the inside, which will eventually fall apart like a normal exhaust, except u get left with a nice shiney outside still with the inside shagged!

The way an exhaust loks on the outside tell you nothing about the inside design and what materials are used.

While the Eisenmann is expensive its for a reason. The quailty is simply the best.

Eisenmann make exhausts for AMG, Brabus and simlar other very reputable companies.

Exhaust design is more than just a set of straight through pipes inside a box with a perforated baffles. You can go to Powerflow and get that and live with the serioulsy bad noise they make and fall apart because the internals are crap.

Eisenmanns also make a very distinctive noise.

I have sum powerflow ones thanks and they sound ok to me

No offense to anyone who has powerflow.

Its more about show with them and very little functionality.

Bootyman - your car is a totally different kettle of fish so the custom design suited you down to the earth.

Next time we meet I will show you what kind of noises a properly designed exhaust can make. You wont believe I have an m20 under the bonnet.

I think you will find that top exhausts also are adjustable for noise, and more, during the manufacturing process, and this is not a feature of, in your minds, lesser exhausts. Also, a life time guarantee would not be given if they expected the innards to fall apart. Good luck with your Eisenman product

Well if you come down with Ant on Saturday, you'll be able to show me Roy offered me the Eisenmanns when i was doing my car, but i was skint at the time and they were just not flsh enough and my car is more about show than go. For now anyway

You suggest that a loud noise is what you personally view as a feature of a "proper" exhaust. That's fine if that's what you're into. Personally, I am not looking for the loudest, I'm looking for something else.

Never said anything about loud noises anywhere.

I have an exhaust on an Alpina. At idle its almost silent, at cruising you cant hear it at all.

You can rev the engine up gently all the way upto 6000rpm and still very little noise. Even during driving rolling on the throttle gently as you do in normal everyday driving - its still very quiet.

However, push the accelerator hard or go flat out and the noise takes on a totally different note and sound level. The more aggressive you are with the throttle the more the noise level changes and its pitch.

For those who have heard this exhaust, they are all quite surprised at how it can change character so much.

To me this is a proper exhaust rather than the usual monotone increase in noise as the revs rise be it whatever sound level they are.

Lots of work went into the Alpina exhaust, the internals cannot be replicated easily. Specific presses for the many internal components are required to make them.

Sounds ok, but to be honest, you're description doesn't sound too dis-similar to my exhaust. Mine is also fairly quiet on tickover, isn't outrageous at all on big m/way cruising revs, but when you're pushing on, it's just fabulous the noise it makes. I was particularly happy the fact it wasn't lairy loud, as I said earlier. Anyway, as long as you're happy, that's the main thing.

Paul

Do you just have the back box on yours? This is a complete system.

If yours has the origional centre section its going to fairly quiet anyway.

London Stainless steel company are quicksilver. They actually make quite decent exhausts. The design is actualy similar to the Alpina one.

Good exhaust!

I was actually quite pleasantly surprised how nice it was. I don't have a full system, only the back box being the stainless, middle section & down pipes normal mild steel. I am considering doing the rest in stainless including the manifold though, but haven't even decided whether I'm going to get the car painted yet (it needs it badly), let alone spend loads on the exhaust. That's me though, I've had the car about 3 years and all my spend so far has been on the suspension etc, bit on the engine systems, but nothing that is visible. One day maybe.

All the best
Paul
