I have mac headers mac o/r H and mac pro dumps is there anything i can do to make it louder and/or get more power

 

if your going to stay mac i would get a mac pro chamber for a mid pipe.

 

it must be loud now. yes?

 

Um Cold Air Intake helps with sound and so does adjusting your timing.

 

that combo will be loud

i have mac unequal length headers, Mac O/R H-Pipe and dynomax Ultra Flows

and its loud but i still have the 2.25 tails on for some backpressure until i get my gears for christmas

 

Here's what I've got, headers, O/R H-pipe and the stock 2.25 inch cat back but it's straight piped, gives me some backpressure, but not enough.

 

I had mac headers, mac o/r h pipe and flowmasters and that sounded really good and was pretty loud. but if your looking for really loud go with some spintech or lm1 and have them dumped and then you will have loud

 

my car is pretty loud and all i got is magnaflow magnapacks dumped.... actually at 1800 rpm u cant really here the radio lol...... im about to install my bbk off road h pipe and that should make it a good bit louder...
