As far as price,weight savings,easy fit,sound quality and prooven performance, I like TT.
used to have it on my mk3 and will put it on my mk4. Just dealing with a custom setup with magnaflow muffler for now and not diggin' it.
it's either TT stainless or mabey the 20th anniversary sport exhaust.
TT is easier for me to get out here in cali, live close to performance cafe
