Sideways

Sideways is running a full 3 inch dual with a Hytech header.

Stock head = stock diameter piping on an SC car. Any exhaust on a turbo car is a restriction, so bigger the better. Its two different operating principals between turbo and SC. Sideways breaks the rule with his SC because of his extensive head porting work, compression ratio and custom cam timing.

ok so i should just do 60 mm test pipe from invidia and do 2.5 inch strait to the back ?

60mm piping is 2.36" equivalent. 63mm is 2.5".

beaudin223

but did 63 mm test pipe exist ? its a big deal to do 60 mm test pipe and 2.5 after ?

06S2k07Si

Yes 63 exists...ideally one should match sizes when possible.

ok i understand , so i should get berk test pipe 63 mm but my question is i need high flow cat in or without ? i dont have pollution emision test in my country so it not boter me , the best option for my supercharger is Js racing headers + 63 mm test pipe without cat or with it and 2.5 inch full exhaust ? i should change something ?

3" is best for everything. Except meeting SOund DB levels.

Sounds good! Bottom line is that there isn't a huge difference in any at about a 400whp level. I personally recommend a quiet system over a loud one...you will most likely get sick of it. Good luck Sir!

Look at the Berk technology header! I think the OEM header is awesome enough, but if you really want a better cost per value for a new header, I'd suggest the Berk piece as its a j's clone without the price
