hi
im getting a pair of shorty style headers for free this weekend..
all know it cam off a 305 or 350 tpi

my questions is...will i need a y pipe made for it or will it fit my factory exhuast system??

check out my stats on the sig

thanx

You will need to have one made from an exhaust shop. The stock y-pipe wont fit with aftermarket headers.

ok thats what i thought....
maybe i should get a catback with that install as well

does anbody know if an american thunder catback will work with the shorty headers??

should easily work. Good choice on flowmaster, i love mine....hooker is also good.

hey does yours sound like a golf bouncing around inside the muffler when u gun the accellerator....
ive herd several flows sound like golfballs...and ive herd rumors that most of the flows have that noise....

my flowpros do that nasty noise.......


and how loud are they at idle and how loud at cruising speeds

i know there real loud if you accellerat real fast.

haha u got it man...at around 2000-2500 rpms....sounds like poopy! If i had it to do all over again, i would get hooker aerochamber, but what can ya do?? other than that, i LOVE my flowmaster to death...i think u can eliminate the rattle tho somewhat by leaving the catalytic converter on...mine is off. I'm not for sure on that one.

It sounds very nice at cruising speed, louder than hooker.

are the hookers as loud the flowmasters.....i want it to sound like my chevelle (i know it will take some work with mods and everything)

At idle, flowmaster is louder....at wide open throttle they're about the same. If you want a loud cruising muffler, then flowmaster would be ur best bet

is there anywhere on the flowmaster muffler that it will tell me what series its from???

my friends flows are so loud.....and they dont make that nasty noise.
either. so im thinking to try and figure out whats on his z28

he probably has the flowmaster 40...the ones made for our cars are the flowmaster 80 series, that fit horizontally along the car

Or maybe American Thunder, its there loudest as far as i know, i just got mine put on. At idle it's just a tad louder than my terminator i had on there before, but it brings tears to my eyes when give it a little juice. Flowmaster :rockon:
