Exhaust question

The muffler does create some backpressure by using different chambers to create noise cancellation. Now, is this really going to affect your performance? Not really...Unless you replaced the manifolds, removed your cat converter, and changed your piping to 5 inch mandrel bent pipes... you're not going to see problems.

I personally removed the cat converter, and put in a 'free-flowing' type muffler on my car, along with 1 7/8" primaries, and the only difference I'm seeing is I'm running a little rich at low-end... so hum... yea, you'll lose about 2-3 ft*lb of torque in the low-end, but maybe gain 1-2 HP in the high-end since you have less restrictions.

You should worry more about getting pulled over and ticketed for illegal muffler.

How ya doing, buddy?

Personally, I think removing/replacing the muffler on a car/truck to make it "sound more manly" is just stupid. But maybe that's because I'm used to seeing kids do it to dinky little Toyota Tercels and driving around the neighbourhood in low gear.…

Heh maybe that explains the most of it. I personally don't like the uber loud sound and have done as much as I can to keep it quiet while having the best possible airflow... it's still pretty loud, but the stereo goes louder...

There's nowhere I can't reach.

I'dd readily fight for that title, any day.

This thing is sticky, and I don't like it. I don't appreciate it.
