This exhaust took about 3 wks to truly break in to the true sound but from the beginning I was blown away. This coupled with O/R X-Pipe will give you a nice loud roar that will not disappoint you, if you want something loud (not deafening just right) and with a great metallic roar sound (no grittiness) this set up is supreme. Can't vouch for these enough.
I find myself turning down the radio to listen to these. Made my 05 GT sound great at any rpm. Tips look great. I would buy these again for sure.
