i have the hks..so far i dont think it rumbles enough but then again i didnt do downpipe and uppipe YET..im probably ordering a few extra things next week..and eventually putting it all on and getting it all tuned.
im probably heading down the shore tonight or else i would stop by franklin mills..i went down a few weeks ago and later that night(10:30ish) it turned out to be decent....but only 2 wrx's...
