Anyone has 70MM Dual Exhaust with Resonated TP?
I currently have T1R 70R Sparrow exhaust with regular TP. I'm thinking of putting a 70MM resonated TP in there because I heard it reduces the loudness. I'm wondering if anyone out there is running a 70mm dual exhaust (any brand) with resonated TP?
It'll be best if you had experienced both sound so you can tell the difference. Also does anyone know where 70MM Resonated TP can be purchased? I've only seen 63mm resonated ones.
Thanks.

did you find a 70mm resonated tp? when i was looking, i only found t1r 63mm resonated test pipe. i bought it and it combined with my berk header, which is 63mm anyways, and my asura 3" dual exhaust, sounds AWESOME!

I've always thought that TP diameter should be either equal or bigger than exhaust diameter.

never heard of anyone running a 70mm resonated tp to reduce loudness, interested to see how big of an impact it makes.
but. can someone explain... why.. it is said quite frequently that you should match a 70mm exhaust with a 70mm test pipe while having a stock header? the diameter of the stock header collector is only 50mm or so. to me it makes more sense to change the diameter gradually, from 50->60->70 (approx) instead of 50->70.
wouldnt a dramatic increase in diameter of exhaust piping leave a larger low pressure area in the corners of the section of piping that is 70mm, causing the exhaust pulses to not make a straight path out towards the muffler? pretty similiar to how a low pressure area above your trunk at high speeds will make air try to circle its way to the low pressure area.
