Flowmaster Hushpower axle-back installed

[FWP!]

I had been deciding between the Roush, Bassani, Hushpower, Borla, FRPP and Magnaflow axle-backs and decided on the Hushpower's. Why? I was 50/50 between the flo's and the bassani's but went with the flo's because I found out they're 409 stainless. Plus they're $150 less. Got them for $412 shipped.

The sound - incredible. The videos on youtube REALLY do not do it any justice. I love the sound from inside the car. People have mentioned drone, but here's the thing. If it does it at all, it's between 1900 and 2000 rpm, plus it's maybe 10-20% louder than normal so it's almost un-noticeable. It's a non-issue to me, and I'm usually a huge critic of droning (been putting exhaust systems on my cars for about 15 years now). But it's got a great, deep, throaty tone, sounds fantastic from inside the cabin. With the windows down it reminds me of what my old '00 GT with a Magnaflow cat-back sounded like going under a bridge.

The fit/finish was perfect. Took me literally under a half hour to do the whole thing and that included using the car's scissor jack to get the car up off the ground a little, and the only tool I used was a 13mm socket wrench.

So after all the decision making I did, I'm really happy with what I chose.

I assume 1/2 hour to put them in, not take your old off too. I am an idiot :lol1:I'll admit, but it took me forever to get 1 muffler off. I could not get to the bolt to drop the front hanger :bash:
I have yet to order and put any back on yet, as it is sitting up on blocks etc in storage. I too didn't have a ton of room to get to it, but it wasn't as easy as I expected.

I love the sound too, but I had to take mine off because of the drone.

I have a convertible with 3:31 gears, what do you have?

I'm trying to figure out why some of us have a bad drone, and others only a minor drone or none at all.

I have the Roushes on mine now, but I want the HPs back on becasue they sound so good...

Video quality issues notwithstanding, here's mine with the before/after.

ETA: I love the new sound, much deeper tone that is felt rather than heard, especially on cold startup. The under-load sound is great and racy. I haven't really noticed a serious amount of drone which surprised me.

I love mine as well. I guess I am different than most I kinda like the drone when the car is pulling. And as stated above the drone really is not that loud

that sounds incredible, is that just swapping out axelbacks or do you also have an upgraded mid pipe? that sounds really good if its all stock into the hushpowers, im putting mine on Saturday morning and I already have a lethal 3" ORX on the car, im thinking its gonna be really loud but i still have the factory resonators on so hopefully those tame it down from what it really could be without resonators....

Here is a video of my car with the same setup as you will have.

I think everyone has the same drone, some people just handle it better.

Maybe, but I'd be surprised they'd sell any of them if they all sound like mine do.

I'm going to try to capture it in a video this weekend and post it up.

I still say it has to be due to some difference in the car - convert vs coupe, rear gears - 3:31 vs 3:73, spare tire and jack vs air pump, etc...

Don't get me wrong - I don't mind a little bit of drone - I'm not whining about what most of us have come to expect with the flows.

Having said that, what I'm experiencing is way over the top.

I've even got some drone at times with the Roushes, when almost nobody else does. Not much, and certainly livable, but it is there.

So I've put 2 exhausts on and had the problem with both.

Has to be something with the car...

That is just the axle-back. Still have the stock everything-else. It sounds awesome, without getting my neighbors to file noise complaints on me as long as I keep it under 3000rpm in the neighborhood.
