Well guys have made 800-900whp with a pt7675 through a 3 inch dp.

I bought a tc7875 and as you know the vband discharge is only 3in any way but just for ***** and since I have the 4 inch pipe already I was just gonna bump it up from 3in to 4in.

Even If I left it 3 in. dp and split it to two 2.5 in. pipes wouldn't that flow enough? Or am I wrong here, I just feel two 2.5 in. pipes atleast flow more than a 3 in. single....

Reason too that I want to do 2.5 is because I have dynomax bullet style mufflers already in 2.5 inch in/out just trying to save a little. Why do dual 3 in. if it's over kill

You know what they say...the best exhaust for a turbo is no exhaust! My personal opinion is that the more you can reduce restriction after the turbo the better. Faster spool and better flow with reduced backpressure. I am sure you CAN do it, but it is not to say it is optimal.

Twin turbo setup correct? Looks beast. Any issues getting it in?

It is a twin turbo setup Chris from CBR Performance did the install and he did the exhaust too.. I won't lie he does some pretty awesome work.. We discussed what kinda exhaust I wanted and he got it done.. I have zero lag and its strong to top end I don't think there's much restriction at all from exhaust

LS1's always make horrible rasp when they are running a single exhaust with no cats.

With a turbo does it reduce all rasp in the exhaust? I'm just wondering if you can run whatever mufflers/pipe combo you want and not have to worry about drone or raspy exhaust with turbos?

thx. Took a while to get there. Working on making my TA like that now.

On the Fbody, does it have stock motor mounts?

stock before, urethane inserts now

fyi from experience, if you build a tight fitting turbo setup around 100k mile shitty stock rubber mounts, it wont fit for **** when you replace them. . .
