i got a 1997 1.8 16v t.s and need to fit a new exhuast system to it, i was wondering if its would be wise to fit a full stainless system to it, and what benifits i would be able to get from it, any help would be great thanks all

Stainless from the cat back would be good. That part of the system always run cooler so is more vulnerable to condenastion (hence rot). Stainless should last longer (if not forever).

A genuine-part back box will last a couple of years typically so it's your call. If you're going to keep the beast, a stainless one will be worth it.

yea i am planning it a while unless i found a q4 in better con, i just love the sound of the 16v engines and was thinking that a stainless would carry the sound better and improve performance, i will do other parts as well but i dont wnat to do things that will cause bigger headaches in the long run,

I did hear that the flow from a standard alfa exhaust is probably as good as you are going to get it (cat excepted), so there's probably not much point in changing from a power point of view....certainly mine doesn't go any better with its Powerflow system. It does look better and sounds different, but then the standard pipe has a great snarl anyway....

I was quite lucky - when I bought my 155 the previous owner fitted a stainless steel exhaust from the cat to the back, so to me it came fitted. One point to note is I had to return to the manufacturers of it a couple of times due to the state of the roads in West Yorkshire!

I found after owning the car about a year the vibration kept fracturing the weld into the front box after the cat (as it is not suported there to the car body) making it sound like a tractor. After a couple of return visits I insisted on them making a couple of brackets to make use of the hangers under the car where I presume it would have rubber loops previous to these models being fitted with a cat.

Once that was done - no more problems, it's lasted 6 years so far and still looks solid!

I have a powerflow fitted from the cat back, and had two silencers removed in the process so just have the back box. There's a noticable increase in power and responsiveness throughout the rev range compared to the standard one but i would put this down to fewer boxes rather than a change in system. Of course there's more noise which is too much for some but i like hearing the exhaust and never find it intrusive.
I can't wholeheartedly recommend powerflow though as they vary from agent to agent, mine were ok but although my system seems to be good i think i was lucky.
I've only heard good things about Hayward and Scott for a custom fit and my friend had his Scooby done there and they were great, but they specialise in scoobies. Second time around i would get them to make me an exhaust though.

oh ok so i f removed the middle box's that makes a diff, i was also wondering what about if i had a pass pipe for the cat as well, then just fit it in at mot, also how does removing the mid silencers go down with the mot
