well with my stock catback it was just a bit louder with alot more "*****" to it, sounded like it was a child stock and a military man with the LT's and no cats

with the cutout on the stock mani's it sounded good but with LT's it rattles windows and makes a nice ringing in your ears

 

Yes...they were Excellent!!!!

I've got videos, they'll be up tomorrow night. One at idle with a few revs, one is cruising, and one is from a 10mph punch to about 80~ish. Have pics as well.

 

W/out cats , they sound AWSOME on an LT1......

 

Well ya heard wrong..I owned one on my old 97

 

I personaly love the sound of flowmaster and have had one on every car that I own but thanks to this post I found that the restrictiveness of the flowmaster was why my car was not get the hp numbers that I expected. I have a lot of mods done to my car and everyone was telling me that I should be getting much higher numbers from my car. I installed an electric cutout for under 300 dollars installed and I am astonished at the increase. I am leaving the flowmaster on for sound but I highly encourage the use of a cutout. Check my signature for numbers.
