I'm not after crazy power just around 400-450 whp
I have a large street port so I know I'll have to take that in to consideration when picking which kit.

Just wanted to see if people can reccomend a kit if they have either.

If you want 400 - 450 wheel hp you will want the S362sxe.

Your definition of not alot of power is quite a lot of power lol. you will need a S362 to make that and I would recommend 1.00AR and defo go for the 3.5" downpipe

cheers

You’ll benefit from having twin gates as well rather than one massive one.
