I found this Monte on youtube.....it is anLS with flowmaster 40's and no resonator......i think it sounds GREAT for a 3400. i messaged him to figure out his full setup....i will post that ifhe messages me back.

here's a 3.8 with flowmaster's

i really really have to find a sound i love though...and i haven't heard that yet...the 3.4 almost sounds better with the flowmasters on it than the 3.8 does

Let me know what his setup is cause when i went to get mine done i was told that magnaflow was coming out with a dual model designed for the mc ls to be converted frpom single pipe to duals.

 

magnaflow is coming out with a cat-back for the 3400 and 3800 but you are looking ar around $850....i dont know about you....butthats out of my range.

i wanna know what it sounds like from inside. i would like to have 40's.....but i dont want that rumble while im going down the highway b/c i do a lot of traveling. i want something that will be quiet when im not accelerating.

 

flowmaster's get quieter @ higher speeds...well at least in every vehicle i've driven that has them

 

he messaged me back.....dual flowmasters 40 series......straight pipe in place of resonator.......stock cat and no u-bend delete.

 

I had no resonator for 3 days and than put a glasspack in. Its way too loud on highway speeds, and super loud on idle and driving around. I got pulled over for a noise violation. Interior noise is disgusting

 

Yeah, I'm keeping my resonator in for those same interior noise problems. Those 40's sound great though.

 

they dont get quieter at higher speeds, they get quieter at lower RPM's. The higher the RPM, the louder they get. I have them on my 86 Z/28 and even at 2,000 RPM on the freeway they are pretty loud, but I love them. Don't know about on a V6 though...

 

i have 2 40 series flows and a res delete high flow cat and it sounds frieken awesome, i will make a new vid tomorrow and get it online for yall to hear
