It is for A4 B6 1.8T Ive already got 14851's mufflers. Now i'm thinking about doing the rest of the piping. Look at the pic
I dont want be too loud though. I'm thinking about 2.5" before resonator, and 2.25" to mufflers.

 

ur exhaust is dual? and why so many mufflers? looks like it'll be quieter than stock

 

LOL )) These are the choices to go with.

 

What is the rationale for going 2.25" after the resonators? May as well stick with 2.5" and get the breathing a little better, for what that's worth.

 

I just dont wanna be too loud... But that's why i'm here asking for some advice ))

 

go with the top picture....

2.5" piping cat-back...it will not be loud, it will prolly just be a nice deep tone...nothing ricey and it will be far from deafening(i can't spell)

gl!

 

go with the upper pic, i say have a 2.5in before resanator, and 2.25 dual after resanator, creating back pressure, it will sound nice

than you need bigger turbo, divert valve, intercooler, ECU flush, stage 10 clutch w/super lightweight flywheel, new wheels, a nice dropp,BBK and etc.

FROM OB to OG

 

Thanks guys!!!
On AZ some guys recommended to go with straight pipes + cherry bombs any ideas???

 

on turbocharged setups close to zero backpressure is actually ideal. so between those 2 setups i would suggest the top choice

 

dude you have a b6, Magnaflow has a kit for your car, it costs 1k so just look at it, and copy it as well as you can... aka ditch the resonator and go with the top pic,otherwise there really isn't any point in doing exhaust, you'll blow a lot of money for little changes
