Go with 2.5 inch from the turbo back no mufflers!!! Possibly one of the best options out there...if you want it very very quiet throw a muffler on it!!

Here is a 3" exhaust with no mufflers so you can get an idea of how it will sound

Before buying anything online talk to local shops. My friend had a complete 2.5" aluminized exhaust custom made and installed for $300 CAD

I had 2 1/4" stainless done cat back in St Thomas within the past year for  ~$200 on my 97 TDI. Stock is metric, between 2 and 2 1/4" IIRC.
I eliminated both mufflers, flows nice & free. Very quiet, barely perceptible turbo whistle.

If you're local & want the shop name, PM me.

will most aftermarket exhausts fit my car?
what are the differences between a diesel exhaust and a gas one?

I'm not sure about mk3s but on mk1 and mk2s the difference is where the exhaust meets the downpipe. There might be a difference in the mufflers, but I don't know

1994 AAz engines in the uk have a cat,i took mine off to put the engine into a mk1 golf,upon looking through the cat,the only clear bit was the middle 1 inch diameter,the rest was sooted up  :shock:  it was binned  :wink:

the guys here in Ontario are pretty strict... like i said i had a bit of an oil leak and they wouldn't pass it drive clean.  the oil leak was little more than a drip...  however we used to have an older golf WITHOUT a cat that had LESS emissions than our van WITH a cat....  :shock:

i have to go for my emissions test in may... quick visual check and off i go with my wallet being $36 lighter....

In Ontario, as with every other place, it all depends on who you know.  Where I take mine to get etested, the guy walked out, walked around the back, and said yeah its a golf, and it sounds like a diesel, and I got my certificate :D

When I got mine done...the guy got into the car (in the parking lot) started it up....leaned out to look at the back of the car...reved it a few times...and signed the paper!!! hahahaha

yea... when i tell people thats all they do for diesels... people want one!  but then again diesels arent for everyone.  most women/men just like to get in and drive... and drive hard!!!  :shock:

i've got one buddy who will jump into his honda at work... won't even let it idle a minute at -10C and just zoom off... sure his car heats up but i wonder what kind of damage he's doing to his motor...  of course 5w20 oil flows excellent in the cold weather though!

I just got my diesel e-tested last night after work....they didnt even look under the car....I would think that if you go to a "good" place they might actually look under the car!!!

Actually, that's exactly what you are supposed to do. Just drive gently until it's up to temp. For a gasser, letting it sit there & idle just ruins your cats cos it runs rich for longer and doesn't warm up as fast.
