Hi there,

I have been looking at the exhaust pipes of my gt4 and as you can see the black collar has more or less completely worn off.

Could anyone recommend the best way to restore this? I could probably do with painting the back box as well - what d'you think?

By the way, phoned ATS Euromaster today to price up some tyres and, if you buy 4, the XWX's are £144 each (includes a 25% discount for 4). This seems, from what I've read elsewhere, to be good value. Anyone in the UK got a better deal (fitted))?

Looks like your muffler is going to corrode through any time now. Perhaps get an aftermarket unit like Tubi and the like. They make stainless steel types and will last through the salty winters.

Do you know where I can get a Tubi and how much they cost? I've had a quick trawl of the net, but as usual spent ages looking and found nothing useful?

I have heard that the Tubi is louder than the stock system. Do you know if it is a track-use only system. (I have got into trouble before for having a race system on my bike). In the UK the road limit for cars is 101dB (I think). Track day limits can be set at 98dB.

Hi Andy.

It is great to read the comments that you have posted on this site. The 308 GT4 that you have purchased looks like a fabulous example, "congratulations".

If your exhaust is in good condition, you could consider removing it from the car and painting it with a High Temperature Corrosion Resistant Coating (HPC). This is a permanent professional finish that will withstand temperatures up to 700 degrees C.

If you feel really enthusiastic, you could remove the header pipes and paint them with the same finish, improving the appearance of the engine bay.

The mild steel exhausts typically last for about 6 years before they deteriorate and rust holes appear. I have just fitted the third exhaust system to my 1979 Ferrari 308 GT4, since I purchased it 17 years ago.

Tubi stainless steel exhaust systems are beautifully made and enhance the sound and power output of a well-tuned Ferrari 308 engine (by about 2 percent I believe).

Ferrari 208 and 308 GT4's were fitted with a unique exhaust system. The shape is triangular in section, when viewed from the end.
Tubi do not make an exhaust to match the shape of the original Ferrari 308 GT4 exhaust, but instead make an oval exhaust that can be fitted to either the 308 GTB or GT4.

An original look was important to me, so I have replicated the original exhaust in Stainless Steel, including the details like the ribs and the tailpipes, to match the Ansa mild steel system previously fitted to the car. The result is a very attractive exhaust, that gives the engine a stronger, deeper sound.

The New Zealand Ferrari distributor imported a Tubi exhaust system for a customers Ferrari 328 recently, the price was about $NZ 6500.00.

The price that you have been quoted for Michelin XWX 205/70 tyres sounds very good. I paid about twice that for a set of tyres a couple of years ago and the supply sometimes becomes scarce.

I hope that this helps.

Donald.
