i have a 1989 GTA 350 TPI i have 1 5/8" headers with no cat hedman y and a american thunder cat back with a muffler that has 3" inlets and 3" outlet to 3" tail pipes.hers my problem for some reason this car is just not loud enough for me.is their a muffler that has 3" outlets like the one i have that is louder? if so whare can i get it? and which one do you recomend?

 

the loudness is partly dependent on the series of muffler you have, i'm not sure which series your system came with....if I had to guess i'd say 80 series. Find out what series you have on there now and you'll be able to get a lot more opinions on which is a louder series muffler. If you want really loud/deep though you can always go with the new super 40 series from flowmaster also, i've heard a few and i'm sure that would be aggressive enough for you especially when having no cat on your system.

 

it is a 80 series muffler that comes wityh the system but the guys at jegs tell that the 80 just means a direct fit they say its not any different than the 40 series which i dissagree also summit or jegs dont carry a muffler that has 3" inlet and 2-3" outlets.when i had a terminator on my 88 formula 350 no headrs just catback with hollow cat it was way louder then my GTA is now.

 

those guys at jegs are full of bullsh*t, the 40 series is way louder than the 80 series that comes with your system. The best thing to do is to contact flowmaster and get the real scoop.

 

Get an exhaust cutout.

 

i dont want a cut out i just want a nice loud rumble.someone has to make a 3" muffler
