I have seen some pics of tC's with dual and was wondering how difficult it is to make that mod. I really love the dual exhaust look and was wondering if it adds any additional power/audible with twin exhaust. Also, how much would a mod like that generally cost?

 

hmm... PrecisionMuffler's dual? spend money... install.

it's like $600-something.... just pm Stylis.

 

Its only gonna add about 1 or 2 whp but the sound is awesome.

 

i'm sure any muffler shop can do it
wouldn't recommend it though
dual pipes = loss of back pressure = loss in torque

gl on your choice

 

yep, dual exhaust does nothing but for looks.
