dont know bout the hedder-but for the best performance and sound it wont come from a after market catback from anywhere.
SAVE your money (people seem to have a hard time doing that here)
and after you get a good set of hedder you should look into a custom setup on your pipes.
pick out a hiflow cat and a can or set of cans and get a custom job done, not only can they give you the sound you want but better hp and keep it carb and emmision legal.
500 to 1000 will hook it up beter then you thought possible
