The New “What did you do with your Z today” (with off topic replies) XXXIX

Though you’re in Cali; may have to either get some nice headers & HFC’z....Z1’s Shorty, FI’ Long Tube or PPE’s Long Tube
Where’s I lives at, heck....you could bout roll without mufflers at all & certainly without cat’s
I haven’t measured the tubing on the oem header, but they aren’t very large

Now on a Turbo engine, the turbocharger creates it’s on restriction/back pressure....so you can exhaust out the hood,fender or flow out the rear w/3” or larger

Heck, as close as you are to Seb....you can go catless & then install for your yearly inspection...then remove afterwards

Seb emailed me, they're going to try it uncorked. My car doesn't pass smog as it is, I could run headers and go catless. I had previously asked Seb about doing headers and he said he didn't think it would make a difference. My car made 680whp with the exact same exhaust with previous blower.

You are going to lose some low end torque when you uncork that thing. A little back pressure is good fo SCers.

We're just trying to find out if there's and obstruction in the exhaust and that's why it lost 50 whp although we gained 2.5 psi. But, yes, you're correct, blowers do like a little back pressure. Basically, we're just trying every possibility.
