Ok so recently i had put on a Glass pack on my car... very surprized to find out how quiet it was.(31' thrush glasspack).. also i had a new cat put on, and it's not a high flow or anything... the glasspack was only put on temparally, until i got some good suggestions on a muffler to put on... will a flowmaster 80 or 40 series give me a louder exhaust... i don't have the money to do a whole exhuast partly due to replacing a $400 catalaytic converter(prolly got ripped off)... so if i could get some suggestions for the LOUDEST good sounding muffler i can get, i would greatly apprieciate it

1998 V6 3.8 5 spd

 

flowmaster is for sure the loudest but in my opinoin flowmaster sounds like a old man taking a hard poo.....magnaflow my personal opinion is while not as loud much more agressive tone....and magnaflow id dyno proven.....

 

Personally I like Flowmaster better... And Flowmaster is dyno proven as well Nic Flowmaster is louder, and personally I think it sounds better. Magnaflow sounds more agressive... For a V6... The way my exhaust is set up on my car though, it sounds like an SS lol. You can hear the engine sucking the air and it's got a nice rumble.

Either Magnaflow or Flowmaster is good though. Louder, Flowmaster... Sporty, Magnaflow... Easy =P

 

I've got a flowmaster cat back, was on the car when I got it. When I get headers (soemday), I'll have an exhasut built at the new shop in town that does mandrel exhaust work. I'll have no cat, and probably no muffler too. No emissions out here. I love exhasut to be loud, but I wont be doing any of this unil I get a cam in, otherwise it will sound like a ricer, as it already does......

 

"Dyno proven" should be used VERY loosely when looking at catbacks, realisticly your almost always looking at <10hp gains.

 

magnaflow 12-13 thats what dyno shows on everything ive seen....

 

Is that cat back, or the whole system? Any dyno runs of straight pipes? That's where I'm going.
