Thinkin of doing custom exhaust....
 

Could I fit two 2.5in pipes side by side like the vm3? Also If I do this system without a muffler will it sound like sh*t? Its just that Vm3 is takin forever!!

THanks

i think 2.5 will fit. I would go with a muffler too, probably be very loud without one

i have a custom exhaust...

my custom exhaust is the meanest and deepest exhaust i have heard yet on an S4....

Can you provide a better description of what you have?

Ask S4Madman - IIRC, he's had 10+ exhaust setups on his S4

What muffler is good to use? Do u think it will sound nasty without one?

Without a muffler you will get puled over just for starting your car cause it will be....
