I bought the mufflers and had a euroshop make it for me, cost me a 650. From the turbo to right before the mid muffler its mandrel bent, after that its 2.5 piping hydraulic bent.

 

my brothers friend has 2 T4s on his S4.

 

Bet that things is a dog off the line.

 

i think i will do a 2.75 all the way back with a euro looking muffler in the back dont know what one tho. i will also take out the resonator or what ever the heck that thing is before the muffler. what were the numbers on the s4 with two t4s

 

I would hope its a highway car, I cant imagine spooling them with 1.35 liters, the 1.8t has a hard time with the t3/t4.

 

You got any pics, or info on that? I know big turbos dont fit between the frame rails and t4's would probably not spool, but I'd love to see some info anyways!
