3" Downpipe VS External WG

[cvcsmkr]

On a Stock turbo setup with open exhaust. And wil be upgrading turbo but not for a year or so.
Goal: Reduce boost spikes.
What do you guys think would work better, and provide most power. External Wastegate?
Or a PTE style 3" Downpipe?

going to a 3 inch DP is going to make the spikes worse, getting a external gate is going to solve the whole problem no more spikes at all. there was a few mini gates for sale in the classifieds you want one of those. or just save up and buy the RPM kit DP, Turbo, and mini gate, or a PTE kit but I like external gates better personally

i have a minigate on its way. i am just second guessing myself.
wouldn't the wastegate have a straight shot out the exhust, thus helping boost spikes. or am i wrong?

the stock wastegate is too small

You need to modify the exhaust housing for this (remove the service port cover). Christian Dionne is the first person I know of to do this, and JS's downpipes are made for this setup also. Christian seemed very happy with the stock stuff's boost control after doing this mod.
