How big of exhuast piping should i go with. I think i am going to get custom exhaust soon but i dont know if i should go with 2.5 cuase i herd that audis need more back pressure. So should i go with 2.0 or less? Also if you want to give me suggestion on what muffler to go with that would be cool too.

 

1.8t or 2.8?

 

Or 3.0, 3.2, 2.0T???
1.8 N/A from the UK by chance?

 

ill guess its a 1.8 T ( could be a 180 or 225 ) only difference is the 225 has twins as standard, 2.5 in stages with resonator boxes could be good and up to 3.0

 

Youre talking about a TT, this is the A4 section.

 

hahaha, go with 2.5" (you can't go wrong)...and a magnaflow muffler...
gl!

 

Ahhh sorry guys i keep on not saying what kind of car i have its a 1.8T quattro

 

2.5" is plenty big for a stock to mild turbo upgrade. Plus the turbo provides more than enough backpressure

 

I have a similar question what about for 3.0 Quattro a 2.5 magnaflow is good?

 

no no you guys have it all wrong. the best exhaust for your turbo'ed car is duel smoke stacks
