Highline exhausts

I honestly don't know, other than the bore sizes are different, so what effect a cannibalised version would have on the engine is anyones guess!

Interesting comments for which I thank you.

I have chatted with one of the business partners, the 'M' in MIJ.

He tells me they've been doing work for Alpina of late & have done at least one 635 before, not to mention lots of E28 based 535i's.

I understood that the Highline system was/is considerably more expenisive than a standard 635 one. I'll be getting Andy at Motormec to confirm costs when I'm back in the office tomorrow.

There is NO way I'd pay a BMW dealer to fit an exhaust, if anything I'd pay an independant or a 'friendly' local tyre & exhaust company - they do most things for a few beers!

Thanks,

Dave

AFAIK, the stealer price for the exhaust isn't too ridiculous, but having it fitted by a BM dealer is likely to make your eyes water, if not the price then the workmanship....

A bit of info from MIJ's website concerning their quoted choice of stainless steel material etc;

Pretty sure that Larini would make up a exhaust for a highline - is there a huge difference between the non-highline and highline systems? Quicksilver are also very good, although I don't know about their 6 series specifics.

Seem to remember someone complaining about bucket loads of extra heat being generated by having a custom manifold fitted, not usually a problem due to the general pantness of the standard manifold. Time to use that insulating heat wrap.

Whilst I don't want to speak ill of the other company you mentioned (the walsall one - I have no experience of them), I would check to see if they've ever built/fitted one to a 6 before, last thing you want is a bunch of Max Power wannabes who are used to bodging knackered Novas. Classic and Sportscar or Practical Classics have plenty of adverts for decent companies. In fact, Practical Classics last month, which would probably have been the August edition due to their ridiculous schedule, had a "featured" spot on a small shop who did custom exhausts for all manner of top of the line motors, Ferraris etc, but would build and fit for anything, and who seemed pretty reasonably priced. I'll see if I still have the article.

did you go for one of these systems then mate?

I've had a good look at MIJ's website & have to say that at the moment they are favourite's to secure my hard-earned......, will also have to ask them about a tubular manifold

Have a look at the website & see what you think - some good customer comments in there as well.

Having looked at the Larini website I've found that they only list 635's from 82 - 87, so quess that won't include the highline.

Thanks sharknose, much appreciated. James Sohl has recommended them as well, by rep not use. I'm trying to find something that isn't quite so steep if I'm honest!

Below is a quote I had from a midlands company I found on the net when searching for 'highline exhaust', but I don't really know anything about them, even though the quote seems quite reasonable. Anyone heard of them, or used their services?

Cheers, Dave

" Dear Dave,

This is Jay from MIJ Performance Walsall.

Thank you for your email.

For a stainless steel system which starts from the bottom the downpipe,
and goes to the rear of the car, on your BMW's you are looking at
paying £599. This includes all the discounts that are available at the
moment.
All our quotation prices include fitting and vat.

Our systems come with a lifetime guarantee which gives you corrosion
and rust free protection, and have been known to improve power outputs.

We have a range of 45 tailpipes that you may wish to choose from if you
are looking for something different at an extra cost

When we fit systems to a vehicle, a cat back system will usually take
3-4 hours and a back box will usually take 1.5 hours. You can drop your
vehicle off and collect it when it is finished if you do not wish to
wait. But you are more than welcome to wait in our reception area, where
you will find a coffee machine and a DVD playing on our plasma screen.
Each vehicle is entrusted to a craftsman who has undergone at least one
years training.

If you are interested in technical specifications; the whole system is
built from T304 stainless steel, with thick walled tube, and assembled
using high frequency tig welding. This will ensure that our system will
genuinely outlast the car and never suffer corrosion from salty road
conditions or create resonance due within the wall tube. This is a common
problem when T409 so called stainless is used in order to cheapen the
price. All our systems are built using free flow technology so your
engine will breathe better than within conventional systems.

We do also provide Window tints, air filters, induction kits, flamer
kits, suspension, engine mods and chrome alloys. For other information on
our services please contact us on the phone number below.

If you have any further questions or would like to make a booking, feel
free to call us on 01922 645646 or E-mail us at
contact@mijperformance.com

Our opening times are:   
Mon – Sat: 9.00- 6.00pm
Sun     : 10.00 – 4.00pm
                                           
We will look forward to seeing you.

Thank you

Jay."

My late 88 built Highline needs a new centre box & possibly a rear box.

Therefore, I have been trying to find a quality, recommended replacement system, preferably in stainless steel. I know Fritz does one (as well as a tubular manifold), but does anybody know of anyone else I could try for comparison?

Or anyone who sells decent second-hand highline exhausts?

TIA

Dave
