Anyone have 4" Inlet muffler?

[4g63telantra]

Just wanted to know is there anyone running a 4" inlet muffler? with 3" exhaust piping or even 4"?

Hows the back pressure?
Sound?
HP gains?

There wouldn't be much back pressure it a 4" muffler with a 4 cylinder expecially if you had only 3" pipe. I also don't think your really going to see much of a gain in HP between 3" and 4" unless you have huge HP numbers. The sound will be about the same as 3" exhaust.

So should a 4"inlet muffler be good to run?

Probably just a waste of money.

stick with 3"

Not very many options in the 4", I'd stick with the 3".
