Mufflers

[beelsamin]

I want to install an aftermarket muffler and I have questions
1. I've heard that the performance mufflers with the 3.5 to 4 inch outlets will kill my gas mileage,true?
2.I want a muffler for the sound more than performance,are there any stock looking mufflers that will do this?
I'd prefer the performance looking mufflers with the larger outlet e.g. 3.5 but if they are bad for gas consumption I'd prefer something
that looks like the stock mufflers but a little more aggressive on the sound.
I don't have a turbo model.
Thanks

The DynoMax #17732 is a great sounding muffler and you can stick on and ricer size chrome tip that suits your fancy. The OEM size outlet is only about 2.5 so won't hurt anything.

Ive got it installed. You can see the tip i put on it. It sounds pretty good, but my mileage right now is 13.8, and its possible that the muffler is the problem. If you want it, its on jegs.com for 35 bucks

I'd go for the real deal, flowmaster 40 series. It sounds great, it has a nice deep hum at idle, and when you break it loose, it doesn't sound like a loud coffee can exhaust, just a nice deep rumble.
