You may have seen my earlier enquiry about an exhaust set up.I have now just put my car up on the hosts and had a look.
I have a 3" down pipe going into my Cat converter, then my resonator and standard piping down to the muffler. I have just noticed that the muffler is TRD muffler (is that standard or aftermarket???)
This is what I intend to do, YAY or NAY.
Keep the down pipe (3"), Remove Cat converter (legal in NZ), keep resonator, then 2 1/4" pipe down to TRD muffler and final out the back of the pretty chrome RPS tip.
Am I going to get best performance out of the TRD muffler?!?!
