whats the stock size of the b51.8 exhaust piping?

 

I do believe it is 2.5"

 

can anyone second that?

Quoted from AWE's exhaust page:

"For the manual transmission system, the downpipe is 2.5" vs 2.125" for stock. On both manual and Tip transmission systems our midpipe is 3.00" vs 2.25" for stock, and our rear section tubing is 2.25" vs a tiny 1.75" for stock."

Hope this will help.

 

my neuspeed is 2.5" I'm pretty sure stock is 1.75"

 

listen to turboquattropwr...he quoted from awe-tuning and they are very reputable and knowledgabe...why are you wondering?...if you are looking to start modding, good start would be exhaust...

 

I am pretty sure that the stock piping of a B5 1.8 is 1.75

 

cool beans...thanks
