SLP POWER-FLO vs. Flowmaster American Thunder Catback

SRT Handz · Apr 8, 2008

So i am considering a new exhaust set up.

Right now i have a UPR O/R-X with a Flowmaster American Thunder Catback.

...I have the chance to Buy a SLP catback with POWER-FLO Mufflers for a good price.... but i have a question....

With a O/R Midpipe will The Power-Flo Catback Be As Loud/Louder than my Flowmaster Catback or will it be Quieter?

I really dont wanna buy a catback that quieter than my Flowmasters so i need your help guys.

Can someone please explain how loud the SLP Power-Flos are compared to another Muffler? I have heard everything EXCEPT the power-flos in person

Thanks Guys!!

I don't have any experience with those, but I am wondering the same thing. I've got SLP LT's, SLP O/R X-pipe and flowmasters.. but i've always been interested in the Power-Flo's

i say stick with the american thunder for the sound... it really is a great combination, i had it on my silver car but im going with some magnapacks for the red one

I think the guy I know had the LoudMouth...and they lived up to their name. Does the SLP site compare the sound of those two because if they are louder than you don't want them.

PowerFlos are the quietest of the SLP lineup(not really that quite though ). I had them on my car before I switched to the LMIIs. They do sound awesome. They have a nice deep tone to them and do get louder after they break in. I would recommend them.
Not sure how they compare to the american thunder though
If you can get a good deal on them, get them, you can always resell them and get your money back + some since you got a deal.

i have flowmaster 10 series single chambers with an x-pipe (bassani) and it is pretty loud and throaty.

i posted a very poor quality video of them a couple days ago. i will post again if you want to hear it...
