Does anyone have the SLP powerflo system on their 05 GT. I just want some info on the sound, is it anything like the loudmouth? And if possible I would like a video or something

thanks

Don_w does. Here is his burnout vid with that exhaust. https://mustangforums.com/m_565984/tm.htm

I'm sure he would be the one to better describe the power-flos, but from reading and listening they are much more subdued than the SLPs, which imo is a good thing.

I was going to buy the SLP powerflo system, I was told that the Loudmouths are louder. I went with the Loudmouth. Sorry no sounds for you, just going with what I was told.

Have any of you seen this and do you think those gains are possible on an otherwise stock car http://www.rpmoutlet.com/05gt.htm Go to the power packages and scroll down to the bottom one....22hp. If so I need to get me some power flows.

Zeio

The Power-Flos by themselves will not give you any hp gain as far as I'm concerned. I don't believe any axle-back system produces more than 4rwhp if any at all. I know Corsa advertises around 11rwhp from their axle-backs, I just don't believe it and call BS. The item in that RPMoutlet package that is giving you the 22rwhp is the xpipe with the high flow cats. Although 22 rwhp gain from that setup seems kinda high, but I could be wrong.

DAVE05GT

Yeah I know about the x-pipe (see sig) but if the stock muffler are still restricting the flow with the x-pipe you could see better gains from the axle backs than if you just had the mufflers.

I know my friend 757GT is selling his 05 powerflo if you want one. Has about 500 miles on it.

How much you want for em 757GT?

I am on the fence between the power flows and the flowmasters... thoughts?
