Off a stainless? wow

let you guys know if i break 100 db next sunday

Hah I doubt youd hit 10db with that! I mean there is still a muffler in it.

when the valve opens under boost, we'll see if i get flagged for a noise infraction

are there sound clips? normally with cats turbo cars don't get that loud!

I should really get on making the exhaust for the car.....the laziness is real...

i'm about to do an autox like event in march for fun, but i'm still running the stock 20" wheels. Not expecting much, but I've read that the sidewalls fold under hard cornering? Is there a recommended pressure to run to mitigate?

38-40 psi hot is what a local rookie ran during evo school.

there will be a few RS guys moving to DS next year (as we run the previous year classing), i am looking forward to the challenge.

Question on the exhaust, I'm planning to measure this next time I change oil but I might ask first. Whats the stock pipe diameter? I am trying to preserve the rear section for use in off season but I'd need to mate that to a 3" mid pipe that we are making. So I'll need some kind of reducer, I just don't know what size to get...

measured the circumference and got an OD of 2.40".

Is that basically the round portion? I know the bit before the muffler is formed pipe and not round I figure if I were to make a connection it'll have to be around somewhere further upstream where it is round...

correct, i measured the tubular portion of the exhaust after the 2nd resonator.
