currently, i have only changed the backbox/rear muffler on my car, to a local Oz product, branded Mille Miglia. i'm very happy with this in terms of sound and quality. this link is for the 156GTA gear, but it is the same:
Alfa romeo 156 / GTA Exhaust, Alfa romeo 156 / GTA Muffler - Mille Miglia - High Quality Performance Exhaust
now i'm wanting to do further upgrades, but want to determine what are the best value parts. i am aiming for both improved sound and improved power, though it doesn't have to be the best in the world! i am factoring in:
*cost: budgeting around AUS$2000; whilst cost comparisons with the UK are difficult, let's just say i want moderately high quality
*availability: preferably easy to obtain locally to me in australia, and not wait 3 months
*ease of fitment: due to time constraints and not wanting to leave my car at a workshop for days/weeks, i am prepared to pay a premium for off-the-shelf premade products that fit; that is, NO custom jobbies
i would say at this point, the actual brands are not my main question. i have in mind to buy further Mille Miglia parts, and probably Arqray, Japan. my question is more about what sections of the exhaust
are best bang for buck:
given the OE ones have built-in cats, i wonder if they are restrictive; but high quality ones will be extremely expensive (eg: Unicorse); 916 GTV headers?
2. front pipes:
are equal-length pipes a good upgrade? looking at Arqray (part 8010FP01)
3. high-flow cats:
would go with Mille Miglia which are meant to be excellent
4. centre pipe:
probably Mille Miglia because i know it will be an exact fit; it is stainless, and straight-through
at this stage - presuming i can get a good deal on Arqray - i am thinking of new front pipes plus high flow cats. any thoughts on this?
and if i do upgrade the headers in the future, do the GTV versions fit straight on without any mods or clearance issues?
