Here's a quick sound clip of my Max after headers installed. It's a straight pipe no cats, magnaflow mufflers. I'm doing about 3/4 throttle.

it doesn't sound refined anymore.

(to me at least)

 

Also I got a resonator installed today because the car was wayyy to loud. I liked it but 100% ticket if I didn't quiet it down. The resonator helped ALOT. No more rasp. It also gave me a little bit of back pressure back so I got my low end torque right where I want it. And my high end still pulls hard. If not harder. I'll get clips of that up soon. High flow cat will be installed in 2 weeks and o2 sensors will be in. Hoping the car will run even better after the rear o2's are in. Not to say it doesn't run good now. It pulls like a raped ape. I think our cars needs a tiny bit of back pressure unless we get a customs tune. The 3.5 motor doesn't like 100% free flowing exhaust. Not say take anything away from free flowing exhaust. I just feel in order for us to get full benefits from the free flow we definitely need a custom tune. I forget the name of the resonator installed but it's a 12 inch resonator. Inside of the resonator had a honeycomb shaped metal. I believe a member on here had one but I think his was a 22". Anyhow it helped a lot with the rasp and definitely got my low growl back. Screams still at WOT.

 

Nice! I can't wait to do mine next year. How many resonator have u added to the car? U mean 22" cattman resonator?

Here's a quick vid of the Max revving. I'll have some up tomorrow of the exhaust w/resonator installed.

sounds awesome bro.. thats my next mod.

 

I like it. It is hard to tell from the youtube video but did the resonator deepen the tone of the sound?

With these mods have you seen an increase in mileage?
