Will changing factory exhaust to after market 3 inch increase mpg very much. I have 200.000 miles and still get around 50 so I guess I shouldn't complain to much.

The car is 11years old, been through 11 salty winters I'm thinking there's not to much life left in that exhaust. But maybe I'm wrong, do you know how many years I can expect to get from that exhaust.

my exhaust is still original and not rusty because its stainless steel and built to last. thats been through 19 winters and 321,000 miles, so yours is a spring chicken and forget about changing it. if you do, a normal replacemnet will last 3 years as they are cheap by comparisson.

Thanks Zollaf for the info. I think I'll let it go then, I'm just kinda getting bored with the car and looking for something easy to do do with it.

a big exhaust will do nothing other than make it louder. its a diesel, if you want performance get a petrol.

well, explain what ? not sure what you mean. sticking a 3'' pipe on your diesel engine won't make it faster, just louder. a remap would make it faster. if you want lots faster, buy something petrol and turbo'd.

I have yet to replace a genuine VAG exhaust on a Golf 4 or 5 due to corrosion, the only failures are of the hangers which are easily repaired. If you want an interesting exhaust for your Golf 5 try try on of these
