well, i'm not doubting what you're saying but speaking from my personal opinion. i had a bike which was an fzs600 fazer which had mild steel exhausts from the factory. they had a paint type finish but this chipped easily. rust quickly consumed them, it was a common problem. it was replaced with stainless steel downpipes and they gave no problems to the previous owner and was fine for me after 14,000 miles, rain, sun or puddles for that matter.
you'd need to stick more than a bit of 2 stroke oil (which is not a corrosive, you should now that) however my golf exhausts seems fine. i'll only find out when the exhaust company have it in to develop the new one on and say "yeah you've got loads of holes".
now the most important part in exhaust design for performance is not material but flow and you can achieve the same flow with a mild steel, stainless steel or titanium exhaust. the only difference is weight which is where the titanium comes in handy as it's light.
now i'm not doubting your knowledge here but when miltek, piper, venom, akropovic, arrow, mtc, beowulf, hks, scorpion, etc, all are using stainless steel as a minimum rather than mild steel, certainly says something.
use of stainless steel isn't amazingly costly compared to mild but means it won't rust regardless of what happens (within reason) - i've never come across a corroded stainless steel exhaust. they are good because they are durable and fairly cheap. if you want to spend double the price on a titanium exhaust which won't do anything other than have a blue tinge to it when it gets hot and weighs a bit less save the money!
also many boat exhausts are made of a cast iron which does not rust when submergered as it's not exposed to air as must. there are also many types of coating (usually ceramic) which are applied. to be fair a thick layer of paint would protect a boat because generally they are not subjected to impact force such as stones, speedbumps, stonechips, etc .
Yeah unfortunately most people can't afford titanium or anything fancy such as that so stainless steel works fine. had stainless steel exhaust systems before on my motorcycles and all been fine. if it's ok on a bike revving to 14000rpm it's ok on my car revving to 5. it's fine miltek, piper, scorpion, akropovic, etc, it's fine for you and me and bob up the road.
hopefully should be getting my free exhaust system soon..
can affect performance and mpg negatively. won't necessarily damage the engine but won't do it much good. about time you upgrade to a stainless steel it sounds like?
Well for example some cars use different methods for example the mk4 golf v5 came in 2 versions, one with a distributer and one with coil packs. so it would different. also try unplugging the maf if it has one (a sensor on the air intake) see what happens comprende amigo.
They would be ok. You'd need to put the M sport kit on it too! the e46's look a bit naff without them IMO.
if i had a bm i would properly euro it, air ride, all that stuff. :>
I was set on getting a BMW 320d or a 330d as my next car but the list of problems seems quite long and it's rather offputting...
First of all is the turbo which you say has been replaced but is there proof of this? And not just an invoice..pics, or something.
Also spend 2 minutes googling swirl flap and you can see what i mean.. if i was going to get one I'd get an 04 or newer car, mid 03 and younger seem to be the most problematic.
although what you'd do to it is slightly worrying after seeing your taste in motors (haha just a bit of teasing mate nothing serious) i'm sure for £2k you could do worse.
I do actually. Hence why i fly 747 first class baby.
that's exactly why. my turbo is a vnt17 which is at upped to around 23psi peak and 18psi hold (hey it's a 118,000 mile old turbo) and an issue which can occur is the vanes get clogged and causes overboost. with this i could see if it happened before it causes damage to the turbo.. also i can see any diverter valve problems, generally keep an eye on the health of my turbo.

and say what you want it's my car at the end of the day.
Firestones = firebomb just check out their history!! Some of the hankook ones are OK, kumho too... Consider the falken ze912s they are quite good as well and cheap!
Goodyear Excellence I had in 195/65 before I changed to 17 inch wheels. Very good. The p6000s are rubbish. Unfortunately it's hard to find sporty rubber in sizes which such a large profile and the excellence is one of the best you can get. a pair with fitting and tracking cost me £140 so you should be able to get them online for that.
Yeah the set I had went after about 5 months but they went about a week after I changed over my bulbs (as I swapped headlights) so I presume it was because of me.
Depends on the type. Some are OK. Before I went Xenons I used Phillips halogen bulbs which were 4k and looked pretty much like a set of Xenons/HIDs.
They had a light blue coating on the glass though, not a full blue one like that.
