Default Flowmaster sucks

I know I always bitch and moan about how crappy my tsp rumbler sounded on my car,I just got back from the exhaust shop because me and a friend traded catbacks,I gave him my rumbler and I got his flowmaster since im getting lts installed this weekend and I figured the rumbler would be too loud,I like the sound better but I can already tell a loss in power the car doesnt seem to have the top end pull like it used to,after I save some more money up im going with something else

And when I say loud, I mean it's really freakin loud! You can hear me coming from miles away out in the country. I live in the city though and it's just embarrassing.

why didn't you just swap mufflers on the rumbler??

could have gone with a longer bullet or something like the borla XR1 and it would have calmed it down ALOT

Yeah...a Flowmaster = lower HP.....but I've seen a Magnaflow vs. a Flowmaster on a dyno with my own 2 peepers...and the Flowmatser sure did loose horsepower..........it lost a whole 3 Horses. WOW!! That's such a loss...I coulden't handle living with myself........(sarchasim)

Put a cutout in the I-pipe with a bullet in front of it. You'll have pretty good sound and great flow with it open. Quiet and refined with that nice Flowmaster sound with it closed.

My flowmaster is costing me 33 dyno proven rwhp over my open cutout. THat is a pretty good bit. But I like the sound and have the cutout so its all good.

the only time i would go with a flowmaster is on duals. not only are they quiet as hell, but like you said. there is an instant notice in power loss.

I would just save and do duals......I know i tried to solve the problem by switching mufflers then doing a cut-out but then in the end duals were the only thing that i liked. Just save the cash and do it right. Been there done that and wish i had gone with duals the first time.

x2 and his car sounds amazing. I guess I can say duals were my first choice too since my old flowmaster cb was on the car when I got it. I'd go ahead and get a flowtech cutout. I knew I was going to do duals later so I just bought a cutout in the mean time. It was a night and day difference, sounded really good and you could feel a drastic difference in power. Go ahead and get a cutout, but I wouldnt waste my time with a QTP.

sounds like your friend came out on top in this deal...

no worries, no need for an entirely new CB system, just swap out the muffler...

So do u have flowmasters and a cutout?? I like the sound of my flowmasters, its not too loud and has a tuned sound to it. But sometimes I feel like being loud , so I might get a cutout. but damn 33 rwhp is a major difference.
