Well i just installed my super 44's from flowmasters and this muffler sounds beefy. But i was wondering:
1. Just by replacing the muffler is my exhaust suppose to on the hotter side? When i drive for maybe 20 minutes and get out of my truck i can smell the exhaust pipes from being so hot.

2. I thought that our stock piping was 2.50" from the cat back? Found out it wasn't.

3. By changing the pipes, would it make a difference in sound and power?

thanks

Is the motor running hot? With a new muffler you are going to smell stuff burning off.

Pipe will make a little difference in sound but not much.

I don't think with a bigger pipe on a stock motor it's going to make a difference but other people on here disagree. It may to a certain degree but...

No truck runs at normal temp. the needle is below the half way point. Maybe that true i didn't take the sticker off the inlet side, but why does it smell like hot metal?

Its just the antirust coating they use to inhibit rust while it sits on the shelf. It will go away in a few days. And the factory pipes are 2.25" outside diameter, very weird

I had the Flowmaster 40 Deltaflow muffler installed and had that same smell... it'll go away in around a week, no worries.
It's what the user above said and also when metal first gets hot it just has that smell.. it's expanding and contracting as it goes from hot to cold... but the temperature is still around the stock exhaust temp.
I also left the INLET label.

Just new metal :p
And it's 2.25" out

Changing the pipes (making them a lil bigger) will give it a little bit of a deeper sound, and it will help airflow, thus increasing performance, but I've been told not to go above 2.5"-2.75" on our trucks...
If you really want a deeper/better sound change the cats and headers and get a CAI.
