i have a 98 Grand Prix GTP with flow master exhaust and i was wondering about the sound of my exhaust i didn't know what other section to put this in so anyway when i accelerate or let my car idle with no pressure applied to the gas i don't hear the deep sound in my exhaust i do when i keep it around or under 2500 rpms when i accelerate fast all i hear is the super charger and when i idle it is extreamly quiet and i wish it could be louder like when i keep it around my 2500 rpms please someone give me a solution without me drilling a hole im my muffler is it a bad muffler? open to any answers thanks
 


i have a 98 Grand Prix GTP with flowmaster exhaust and i was wondering about the exhaust sound this forum had the most viewers so its not that big of deal its in a different section but i noticed that when i keep it around 2500 rpms i get a good loud low sound to it but when i let off the gas it is very quiet when i accelerate fast i only here the super charger and when its in park its loud but as soon as you shift to drive its quiet can someone please tell me how i can make it loud all the time bad muffler? and no drilling holes in it please need more info ill post it thanks
 
Your exhaust is working the way it should. You shouldn't hear much when you let off.

If you want louder, then either swap out the mufflers, or put in headers. If you want stupid loud, put a cut-out right behind the downpipe on the header.
 
could delete the resonator but you will get mega drone.
On another note you shouldn't make 2 threads about the same topic, one thread will most likely get deleted or get merged into one thread.
no biggy, now ya know :th_winking:

You want v8 sound I'm guessing (as everyone does) remember they have 2 extra cylinders lol. But to have a rougher idle, change the resonator with a straight pipe, or smaller glass pack or some sort of different resonator. Or get louder mufflers.

its louder outside than it sounds from in the cabin just remember that. if u want loud everywhere res delete can help with that. yes there will be drone but if you want it loud you shouldnt care about the drone. next step is headers.
 


Decided to rez this old thread for my question, how are muffler deletes? they always sound really good in videos and what not but i don't see many people with them. it seems to not be raspy, decently loud, and growls nice, why does nobody do it?
 
do it, then you will see how it really sounds. then 3 days later your like this sucks, and put the mufflers back on. these engines just dont sound good.

leave it stock and quiet and enjoy it. at least thats how i feel. some like it to be louder, but ive yet to hear any 3800 i liked, on you tube or in person.

hell i just met a guy with a stage 3 regal and he had a slp cat back, i didn't like it at all. sounded like a wet fart.
 
I mean on the videos it doesnt sound bad and the people who did it didnt complain but theres only a few. It just sounds louder with no rasp, because the res is still on.. hm.
