Longtubes made my car quieter

I had heard this but was not sure. I just finished putting on my 1 3/4 long tubes and Dr. Gas X-pipe. The sound is quieter but deeper than my oold BBK shorty BBK O/R X. Plus it got rid of my drone. I had terrible drone at 75mph but now its almost all gone! Im happy. Now if i can just find out if i made more power that would be great.

i went from stock heads, stock headers, mac offroad X pipe, mac pro dumps
to
trickflow heads, mac longtubes, mac prochamber, mac pro dumps
the idle is the same volume, and sounds good, WOT is quieter and honestly i dont like it, i think im gonna go with a new midpipe or maybe new mufflers

Everybody says my car is really quiet at idle. I think it is too. At WOT it is pretty loud though.

Get rid of the prochamber.

go to the rear of the car.

the set up I had was mac shorty equal length headers with mac off road H-pipe and flowmaster american thunder out back... It was pretty loud with that combo.

I recently changed to the prochamber pipe and it defintely made things pretty quite at normal driving and idle. But it does get loud at WOT.

Oh yeah its still loud as balls at WOT but i like the mellow tone now. Its deeper.
