HKS hi power too loud (fix?)
HKS hi power too loud (fix?)
New to G's
I just bought an 03 Greddy TT G.
It has a megan resonaed DP and HKS hi power.
I find it too loud for my taste. (Iknow, I'm getting old)
Have anybody try to add extra resonators or something.
I had an MKIV single supra with HKS super dragger and it was super quiet while cruising...
Suggestions are welcome.
Thanks in advanced.

Put two potatoes in the titanium tips and it might quiet the system up a bit 
But really the only way to make it less loud is put stock cats back on but then there would be no point of having the TT. Just swap the TP's out for High Flow cats or resonated TP's and it will get rid of the rasp. Still loud, but no rasp

You are probably running test pipes then that aren't resonated. You could try switching to hi flow cats. The HKS Hi Power exhaust is pretty quite on idle and while cruising and your TT kit should have quieted it down even further. From this I have a hunch you are running megan test pipes (not down pipes) and megan's exhaust products are known to crack and just be overal bad. I would therefore say switch to something like crawford high flow cats.

+1 for the tt's quieting your exhaust up, though. they should.
+1 for switching over to high flow cats.
