Well, Timmays tips arrived yesterday & installed today by Woolf mufflers in conjunction with the muffler delete. So, what do I think?
Timmays tips are excellent. They are slightly larger, but not boy racer-ish & all the better for it. Excellent workmanship too. Well worth the money.The Kiwi M5 script looks awesome, but is not so obvious as to look like I am pimping the car.
Onto the muffler delete. T'was quite a job getting everything lined up & but Jason brought it all together in the end. Total time was ~2 hrs & only $200. Good value. As to the sound the car now makes, here is my opinion after 2 separate decent drives around town & the motorway:
Up to 2000rpm, it sounds like a cross between a old style Subaru flat four throb & a lumpy V8 & in a good way.
At about 2200-2400, there is a higher pitch crossover note which is semi-drony but only if you sat at those revs. From about 2500rpm, the V8 sound really starts to come out & sound something like a cross between a NASCAR V8 & the Chevy V8's. Very very addictive.
As described, the exhaust character changes across the whole range, but with the standard mufflers, it is pretty much the same, just different in volume.
At a constant 100km/hr the exhaust volume is only mildly louder, but in a nice way & not really noticeable. Just as you pick up speed, you get that higher pitch crossover sound for a moment & then the V8 sound comes through & it is really quite something.
I am looking to take a trip to Hamilton this weekend & see if it this new exhaust character grows on me or, if after 200+km, the novelty wears off at which point I will simply put the original mufflers back on.
The other change I am look at is a ECU tune by Torque Performance. I have been advised that their are gains of 15kw & 20nm. I am waiting for the before & after maps before considering making this change. It will either be this or the Evolve Alpha N MAF-less tune. They are both about the same price. I am still to make up my mind on whether I want or even need the extra power. I won't be taking the car on the track & I already find it hard enough to stay within the legal limits as it is.
Other than that, all is being kept stock & that includes new front discs, new shocks & tyres all round & a few minor mechanical & cosmetic tidying before Xmas. That should see just regular maintenance for the next 1-3 years. IMHO, I think BMW pretty much got this car just right.
I even took a 02 Porsche 996 twin turbo & an 08 Nissan GTR for a test drive this week to see what sports car I could get that would eclipse the M5. The Porsche was a disappointment, primarily because the combination of the auto & the turbo lag conspired to be a foot down, wait for hit, whoosh, now we are away. That is no good after a torquey NA V8 (a manual version might be better). The GTR was simply amazingly faster in every possible way. It does things a car shouldn't be able to do. Problem is the oragami styling, the badge & the Japanese script on the control screen (was an import). I couldn't bring myself to pay out ~$100k for this car, not matter how fast it is. Bloody amazing car to drive though - everybody should have some behind the wheel to at least get a benchmark of what fast & amazing handling can really be like.
BTW, I have a Valentine 1 radar detector on the way from the USA via a friend in Georgia. It cost me less than most of the secondhand units selling on Trade Me & that are 2-5+ yrs old. Don't let others foll you into believing that the 'NZ' units are especially tuned & require some sort of super knowledge to tune. It is a simple matter of deleting the K band option. Yes, it really is that simple. Better than paying ~NZ$1,000 for a 'NZ' tuned unit.
Finally, the only other issue I currently have is water/condensation in the drivers side headlight. I have used the hair dryer several times, but is always comes back. I thought the O-ring for the headlight adjuster was the problem so was replaced. I have checked the drains & they are OK too. Looking at all the other comments, it would seem that the rubber that sits between the lens & the headlight unit may have perished. I will pull this apart & try to reseal it or buy a new rubber altogether.
