Having the exhaust done this week... Questions. 5.7L

I'm having the exhaust done on my 05 wk 5.7L this week. I'm looking to help slightly increase fuel economy(along side intake and all) and get more performance and a better sound. I don't want it to be obnoxious or anything, just a nice rumble at idle.. deep growl around town and on the highway... but roar under heavy acceleration.

I'm a big Magnaflow fan so of course the brand is not in question at all. I found a video clip of the 11226 Magnaflow(14" body/20"overall) with factory resonator and it seemed to be almost exactly what I want. However, I saw on another thread someone had the next size larger(18"body/24"overall) and complained it was too loud. Isn't it the longer the muffler the quieter?

What's your guys input? Here is the clips of the one I heard and loved.

Hard to tell from those videos. Sounds stock to me, so I don't think it would be too loud. Need to hear it at idle vs wot. They could have given it a bit more gas in the drive-by.

If I were to do it, I would get rid of resonator.

Also, don't expect to see any mpg/hp gains from this.

Re: tiHaving the exhaust done this week... Questions. 5.7L

I am also thinking of either getting a MBRP or a Magnaflow (Just the Muffler) I just can't decide! I made a 5.7L Exhaust thread to see all the different kinds of mufflers that sound good.

In this video though it doesn't sound much different. I can hear the tone, but I'd expected a little more out of it.

Re: tiHaving the exhaust done this week... Questions. 5.7L

I had the new muffler put on tonight. It sounds a lot louder in the video then in person because i had the camera so close to the exhaust. It's quiet when I want and loud when I want and that's what I was looking for. noticed a 1.5mpg gain on the highway coming back from Reidsville too. If I didn't drive the exact same route both directions and the same speed with no differences in traffic, resetting the average gauge both ways I'd say no way but that's the facts. I've had compliments galore on it since I got it on.

yes I did keep it on. I wouldn't to keep it fairly tame. I love it. loud when i want. quiet when i want. I do wish it was a bit louder at idle but it sounds much better then stock. had a nice low deep idle now but slightly quiet.

Re: tiHaving the exhaust done this week... Questions. 5.7L

Can we get a video of it like away from being up close? Like from a Far Distance and an in cabin video if that's not too much to ask for! Which Magnaflow did you go with?

Re: tiHaving the exhaust done this week... Questions. 5.7L

Eurotrash,

Man that sounds great what does it sound like in the interior any drone sound. What magnaflow mufler part number did you get? I got resonator off my 5.7 with the stock muffler.

Chris
