Here is a vid of my cat-back with stock Lt's and Y-pipe:

I think I'm going to get a magnaflow to replace my flowmaster catback.

 

What are stock LTs?

 

Um in that video you found I would like to inform you that he had long tubes on it and on an LT1 none the less. Magnaflows are slightly more aggressive than stock mufflers on LS1's . You will be dissapointed. Get Borla or a LM1.

 

i just installed ma magnaflow on my 98 w/ stock manifolds/cats and i love it. i think it sounds great, quiet at idle/cruise but mean at wot.



on a side note, i have the single tip setup and was wondering how people straightened out the drivers side tip because mine is crooked and sits against the bumper.
