4.0 Sport Exhaust setup

[scorgnetic]

All right, I am getting ready to put duals on my girl and I am looking for some input. What I am thinking of doing is running 2.5 H pipe and a flowmaster dual 2.5 in / dual 2.25 out. Does this sound feasable?

Thanks

I wouldn't mess with the exhaust pre-muffler. Just get a dual out muffler and run duals from there. Depending on your truck, you may need a dual in or single in, 99s can be either.

Be aware that many installers will not run duals with your spare still installed, you may have to hunt around a bit for someone who'll do it. I'd run dual 2" pipes out.
