I have a 2000 TA no ram air... I have just added a Flowmaster Muffler but want it Louder..... In my 91 mustang I put Flowmasters on it and it sounded much louder. I just did not get the sound I was looking for on my TA. What else could I do without effecting the computer. like I dont want my engine light to come on becouse of some mod

 

Ditching your cats will make your car MUCH more noticable, but it can be a pain to get it ready for emissions. If LOUD is all you're after, not much is louder than a cutout, no cats and long tubes.

 

Get rid of your cats

 

Or you could just ditch the Flowmaster setup and get a Loudmouth

 

Remove ALL restrictions in the exahust.
LT's, dual cut outs on Y pipe=LOUD

 

if you want it real loud, get extensions welded on your headers and send them straight towards the ground.

 

If you simply want your car a LOT louder go with the SLP LM or a cutout. They sound like crap IMHO, but they'll get the job done for you.

Either get a Loudmouth or get LT's. Either one will make the car louder. I wouldn't ditch the cats unless you plan on building the motor as stock motors sound too cackly and have too much of that farm truck sound. Also a freer flowing Y pipe would help out some too.
