Dumping exhaust after muffler........

[4x4Yota]

When you dump your exhaust after your muffler are you going to warp you heads by not having enough back pressure in having the hot air being pushed out and the cold air sucked int?

I've been running my Ranger which is a daily driver with the muffler dumped for months with no problems.

Like everyone else said its fine. I have no tailpipes on my truck or my chevelle. Both have flowmaster mufflers and both sound great.

You'll be fine, just don't run the truck with open headers
