JUST AN FYI,
the hard mount vs spring mount of the pipe to turbo makes the pipe to y-pipe move more, this made my y-pipe crack/break three times last year...im sure it will be better on a pump kit as i had a race kit.....but this hard mount is just a silly idea IMO
best of luck to you:beer;
i would also only run 8 springs on the y-pipe side, more springs makes it too stiff and 8 springs works just fine....i also dont like using both turbo spring plates on both sides of this y-pipe to pipe, i just use the lower side sping plate.....let me know if you can't vision what im trying to say
