i did it on my avant, 3 inch turbo back with the smallest box on the rear. sounded nuts. do it!!

[HORCH]

well I've just decided to have a straight through after listening to tonks's car until I get a 3" system made up then I'll use the smallest box I can find

[JP]

I had a straight through 3" system with single magnaflow back box. It was so loud I gave up listening to music anywhere over 3000rpm. At idle it shook the windows of the house. A motorway journey over 30min gave me a headache. Keeping in mind I suffer from tinnitus from my early musician days getting a headache takes some doing.

I then added a centre box. And although quieter the drone was unbearable after a while to the extend I no longer enjoyed my car. Everyone loved the sound but they didn't have to live with it as a daily. Even my old V8 with 2 4" side pipes was more bearable.

I've now bodged a stock back box onto the 3" system with magnaflow centre box and the car is a bliss to drive. A bit of a rumble. No drone. Nice rasp at the race track. Meaty burble at idle without rattling the double glazing. And best of everything it has turned the car into a proper sleeper.

Just my 2p although mine is a daily

i have 3 inch pipes, a 100cell cat and a small muffler at the end. and screamer pipe.
doesnt sound much going on the hight way, but when you get boost all hell breakes loose.

heres my S2 LEAF BLOWER. Thought i'd see what it sounded like when i was removing a damaged middle box. I was tempted to just run a 3" straight through stainless system, to give a nice raspy note, but im just running a scorpion backbox now, nice and quiet. http://www.youtube.com/watch?v=QYOWc8LTaqY

So anyone with a straight through TDi??

[MJF]

TDIs with tiny turbos are very different than gassers with straight pipe. Small turbos are good silencers, vnt´s even better. There are videos in youtube, one for example.
