TRD Exhaust W/ Hi-Flo Cat
Is it worth it to get a hi-flo cat with a TRD exhaust, will it add any hp and will it chance the sound, cause i love the TRD deep sound i dont want it to become raspy.

no the cat on our celicas is already almost as high flow as you can get. I would go have a straight pipe welded in place of your resonator. Free up a little air(but not too much) and make your car sound a little more tuned. If you go too free flowing your going to get backpreasure problems. Also a header would be good
