I was wondering anyone treid 400-450whp with CT S/C NOVI1200 with 400-450whp with 60mm aftermarekt dual exahaust with 60mm test pipe
60mm piping size some around 2.36 inch diamter
anyone tried?

Should probably look in the fi section. Pretty sure there is plenty making 400+ with a sc setup not sure with that exhaust though.

I have Greddy (not sure either 60mm or 63mm) dual Ti-c exhaust
And I like this dual exhaust but if I can make 400 plus HP I don't want spend extra money to buy another 70mm exhaust

Habitforming

you don't need a 70mm exhaust to make 400hp. You can do that through the stock exhaust

picco97

Are you sure stock can make 400whp with super charger setup?
I believe stock exhaust less than 60mm piping diameter

There are plenty of people making 400+whp with stock header and stock exhaust. Most will either use a 63mm test pipe or HFC though instead of the stock cat because it's so restrictive.

I have invidia header bigger than stock and 60 or 63mm test pipe plus Greddy dual Ti-C on it (60mm or 63mm) I'll try Dyno soon and will post it how much I can get

There are stories of people using the 60-63mm piping instead of the 70mm because it performs better with the supercharger. I don't know how accurate this is but there were a few cases where people saw an increase in boost due to back pressure apparently.

picco97

Hmm it's weird how can 60-63mm better perform than 70mm exhaust

I'm getting 420whp on a dented hks header + stock cat + stock catback on the Novi 1200 on the 3.2" pulley + E85. There's another guy here in Aus hitting 470whp on a C38-91 with stocker header-stock cat-stock catback.

I remember a thread here saying the exact same thing Braeden said regarding more back pressure delivering more boost for SC setups.
