Default why isnt my mustang loud??mufflers? cat or cattless and headers?

so i curently have a 2004 mustang with a catback exhaust(flowmaster 40's) and a custom h pipe. my question is why is my car not loud and what would make it louder? im ordering a cia tomorrow morning and i hear that will make it sound better adn louder while adding hp? what about headers? will adding shorty headers increase my sound and hp? or is it a wast of money? also i herd u can chop off ur cats and replace it wiht it wiht strait tube? would theese be the ones under the car at the positioin of the doors? what are the efffects of this and any gain in hp?

thanks so much'
connor

A V6 will never be as loud as a V8 if you go on youtube and listen on there.. A CAI should make your exhaust a little louder.

if you have cats your car will always be quiet.

take those off and expect to see a 5 to 10 HP gain

i did headers and h pipe on my 5.0 and it stayed quiet till i took off the stock mufflers and it was loud.

my old 94 v6 i did high flow cats and mac mufflers and it was loud but very quiet at idle.

ur car is going to be pretty quiet at idle anyway not a whole lot is goin on when ur just idling... getting rid of the cats is risky business.. ull end up with alot of rasp without them... loudness isnt everything.. u may get it louder but it might sound kinda crappy..

You tune and tweak until you see GT's falling behind you.Then when they ask "Is that a V8?" You simply respond with a rev that clearly states "I'm a V6" with a proud smile on your face. As your girlfriend sitting on the seat next to you calls you an idiot.

Get longtube headers over shorties. You will see no gains with a shorty as they are pretty much identical to the stock ones.
Taking off the cats and mufflers is going to make you lose a lot of back pressure. Without that back pressure expect to lose torque.
If you want louder get some longtube headers, a custom midpipe with high-flow cats, and mufflers like; Super 44's, SLPs, Cherrybomb, etc.
