ok i have a ? see i just took my exhaust off and im gettin a hooker cat back system like on monday or so will driving my car without a muffler affect the cat or harm it in any way thanks for reading - devan

 

nope, i drove like that for months

 

hey thanks for the reply so your positive it wont harm the cat im not that worried its just my parents are **** about my car but im getttin a hooker cat back system on monday at the earliest

 

Tt wont harm anything. I ran without a catback for months in the dead of winter too and everything worked out fine until I got my headers and full exhaust on.

 

only thing its gonna hurt is your ears man ...lol..

 

yeah well it dont hurt the ears just now its startin to get annoying thank *** im gettin my new cat back on the 25

 

ok well got the hooker cat back now i cant even hear the damn thing lol awell i guess its better then stock but still i thought it would at least have a better sound

 

Make more power, you'll get more noise

 

no mufflers is definately the hill billy approach, but as long as the cops don't bother you then it's ok. I am guilty of no mufflers for a while as well.

Now i have spiralflows, they're about as loud as i can handle for a friday night fun car.

 

u gotta remeber though i have a ****ty *** lg4 its hard to squezz any power out of it

 

also this is my first actual major upgrade im thinkin next headers and new y pipe

 

i ran without anything past the cat for a couple months too.. i would probly have put a catback on it, but it honestly just wasnt that loud with the L03... low power motor and manifolds and the cat maked it quiet enough that i wasnt bothered... i also have a vert, so the sound can excape the cabin easily... that probly helped.

 

...and any respect you've ever gotten from f-body lovers in your neighborhood.

 

oddly enough, i got a ton more compliments about my exhaust with the catback off then any other exhaust.. ever.

couple of points though:

1. its a 305. that means smaller bore. it makes a slightly diffrent tone then a 4" bore motor. it just doesnt sound as sh!tty. most 4" and larger bore motors (350s) will sound cruddy, hence the stereotype

2. with manifolds and a cat, you can bearly hear it at idle... the sound is still muffled.

3. it will vibrate the floor pan, so you feel the exhaust..... some dont mind, others find it annoying.

 

i got the cat back now so im not worried anymore just now what should i get for more perfomance im guessin headers but which kind should i get any help would be appreciated

 

Same thoughts here. I was nervous when I put in my cutout thinking it may start making the annoying popping/gurgling of straight piped trucks, but it didn't, it sounds awesome. I can barely hear it at idle, I swear with it running through the flowmaster at idle it is louder. My floor pan vibrates a lot, especially when my tranny goes into OD, tickles my feet and the women like the vibration in their seat.......

 

I'm not running a muffler right now, I kind of like the burbling sound when I let off the gas. And yeah, my neck happens to be red right now. (too much sun at the autocross track) It's not going to stay that way, but I'll enjoy the sound while I can. It's only intolerable when accelerating in a parking garage.

 

yeah that always sucked *** lol it was sorta embarassing untill i just rev hella next to sum old couple then it was funny

 

no doubt
