I have heard chevys around here with gibson and they arent really even close to the sound of flowmaster, the closest thing ive heard to my 40's are magnaflow, and i still dont thing its much of a difference at all. My truck has a nice rumble just idling, and can hear it driving, but not so much on the highway which i like.

 

Im all about going with flowmaster. I have the 40 series. Good deep idle, you can defenatlly hear it when you step on it and it mellows out when freeway speeds are reached for a nice comfortable ride.

 

What are the louder ones? 44s?

 

44s are the loudest flows other than the 10 series

 

k, thanks!

 

I had flowmaster 50 series single in/ dual out installed last month. It really rumbles !!!

 

Flowmaster 40 single in dual out all the way baby!!!!!!!
havent heard the 44 but the 40 sounds good. could be a little louderat idle and low low rpms but dont want to give up that great flowmaster tone for some rice burner sound or something.

have a good one.

 

Thanks for the replies guys. A guy I know suggested Gibson. One reply said they werent that great. But they advertise their performance side swept exhaust as being quiet but aggressive. I'm just afraid the flowmaster 40 will be too loud. Arent the 70's quieter or something like that? Anybody running them? I know I'm trying to have my cake and eat it too....

 

the 50 series isnt as loud as the 40 series. i was unimpressed with it on my k5 but if you dont want to loud i would suggest it to you.

 

I have the Gibson Super Truck and it sounds great! It exits out the side of the truck just in front of the passenger rear wheel. So far, i haven't seen anyone in my area with a setup like this and I constantly get complements from other truck owners on the sound. The only complaints are from my neighbors when I fire up my truck at 6AM!
