I'm running a 3" full X system out the back hoping I will still run 95 percent of potential. You think I will see back-pressure at that point in the collector?

But I will check for back-pressure before I use it, thanks.
What type/brand check valve should I look for?

And should it be far enough away from heat so it lives?

P.S. this is an old MP .484" degreed to shift at 5500, trap at 6000
