flowmaster 80 series and lt's
 

i have the flowmaster 80 series muffler on my car and im getting jet hot long tube headers and ory installed, what is the sound gonna be like after the lt's get installed, i kno that the flowmaster isnt a good flowing muffler but will it still sound good?

should sound ok, so you have just the muffler and not the whole cat back?

I had my SLP's and y-pipe put on before I got my CB. I had a 80's series on there. There is a difference between the stock manifolds and the LT's. With mine it sounding cool. It even had that slight "Mustang" hollow sound to it.

whole catback, there is no difference between whole catback and just the muffler. the only difference is you get tips and the other pipes. it sounds nice and smooth on my car with my cutout closed but thats a rare occasion.

am i really losing power by running this muffler

Not that much really, depending on HP...btw..it will sound great IMO.. :judge:

i think my car is so where in the area of like 345 ish right now but im not to sure
