Largest exhaust resonator removed

Okay so after some debate, I had the largest of the two exhaust resonators cut out of my factory system. I've had aftermarket 3.5" tips for a while, and I thought that was too attractive not to have sound.

The result is that there still isn't that much sound - which is good. It growls on start-up, but is barely audible at idle. From 1000-4000rpm it is a low growl. Roll up the windows, run climate control, and listen to the stereo and it's no different than stock - silence.

However, it does make some nice sounds now. Since my mufflers are stock and one resonator is still in place, there is no annoying resonance or droning.

It cost $40 and I don't regret it at all. If you want to add just a tad bit more personality to your TL, but like the stock look and don't want to spend much, this is a good way to do it without looking aftermarket (which I can't stand).

Oh yeah, I forgot to add that it was Kris's support for this "mod" that made me do it.

What kind of tips did you get?
Besides removing the resonator,the exhaust is stock?

It was close to the actual mufflers themselves. And yes, all my exhaust is stock. The tips are Pilots, the outlet is 3.5"

Guys I believe 03CoupeV6 is referring to the premuffler. it is a big resonator closer to your mufflers. I was going to do this mod too, but got a great deal on a magnaflow catback so I went that route, love the sound.

I'll work on a soundclip, but it's really nothing major. It just has some sound now as opposed to being silent. It doesn't sound ricer, it just sounds like a V6 with dual exhaust. A toned-down version of a 350Z for example.
