i LOVE the sound at cold startup but then it doesnt give a muscular sound after warmup IMO

when i got these it was either the HPs or the SLP LMs, i shoulda gotten the SLPs

anyone else have remorse with HPs?

i want a muscular sound without sounding like a redneck pickup

 

I almost got the Hushpowers but purchased the Roush's at the last minute due to a sale that was going on with them. I heard a few of the youtube soundbytes and the hp's sounded pretty decent imo.

 

maybe i just need an O/R X

 

they are called HUSHpowers lol I'm not even sure why people buy them.

 

I went through the same thing. I loved the sound of the hushpowers, but they were just to quiet (I know they are called "hush"powers, but they were supposedly the best sounding axleback on the 2011s). I wanted more sound so I removed the resonators...then it just sounded more like a glasspack at WOT...didn't change the volume at crusing or idle.

I finally did what I should have done in the first place, and bought the borla s-type catback. I only installed the axlebacks at first and what a difference...sounded very close to my 2001 2V Mustang GT exhaust (o/r x and flowmasters). These things really roar. Then I installed the rest with the x-pipe and this quietened it down a little and smoothed it out. Should have spent the money up front instead of trying to cheap out...lesson learned.

 

.... i have had nothing but compliments from people that heard my exhaust..

 

Yeah, the hushpowers seem a little quiet, but it's kind of expected with their name. I was planning to do an off-road h or x, not sure what it will sound like, but I'm waiting to see the sound difference after adding a blower.

 

Any muffler delete... Roush, SLP, Pypes, Boomtubes, etc., will be louder and sound better IMO.

 

did you get the axle back . i went with the hushpower cat back they sale. it comes with a xpipe and gets rid of the bottle neck up front the sound is great also it is a 3 inch all the way.pn 819112

I'm running pypes catted x pipe and pypes pypes bombs...could not be happier with the sound

 

I like the Flowmaster HP but after a while they were too quite, but the sound was much improved with the whole setup - after cat pipes and x-pipe. I was looking for the old-school 5.0 sound.

 

My 2005 with heads, o/r h and FRPP exhaust is outrageous, so I went with the HPs since I daily drive the 2011 in fair weather. Quiet at idle, opens up at WOT. Works for me...

 

Exactly. Hush is in the name for a reason.

 

That will definitely open it up and give you a better sound. But I don't know anyone with HPs and an OR X-pipe... Good luck!

 

There's a video floating around YouTube with HPs, headers, and a o/r pipe. Sounds vicious

 

Same here

 

The hp's are a flowthru design... At low pressure / idle the deflectors muffle the sound, at high pressure / rpm they flowthru just like a straight pipe. If your "idling" through an area where loud pipes could get you unwanted attention, they're muffled, stomp on the go peddle and they're as loud as a straight pipe,.... Perfect for an older, refined more sophisticated driver, makes em not pay attention until you want them to.

 

I like mine but the whole reason I got them was to quite a future o/r x pipe.

 

I love my hushpowers! Not too loud and not too quiet. Perfect!!!!!!!
