would a 3in downpipe cause boost spiking with a stock k03s turbo? Looking at a downpipe since $250+ is crazy for a downpipe. I was looking at this one:

and then there is this one for $75 more and its a 2.5in one

hmmm...neither of those links have a downpipe in em...

the first link is for just a testpipe and the second link is for a testpipe that looks like a cat...

as far as spiking issues go, you shouldnt have an issue...but if you do you can easily take care of it with an mbc
gl!

 

plan on getting a revo cal the day I get the exhaust put on.
