Can the Schnell CAI $100, save $97 and do the shaving foam cap mod, absolutely no difference in sound

frisbee91

+1 for the Fister-style muffler hack. $200-$300 ish

Invius

Definitely the motor mounts if you need them or haven't done them. I would have done them first had I known how good of a change it was.

Mark I

Krazy K's innovative IMSB replacement - under $100.

The emotion anything IMS generates...priceless.

One recent "mod" I did recently was a LED 3rd brake light as the factory one is incandescent, believe it or not.

You can get this in red, smoke, or clear for under $100.

I was really surprised that a $100k 2001 model year car didn't come with them.

rpm's S2

Fister D mufflers. Went on a short back roads run with a group last weekend and friends were lining up to run behind me just to hear it!

Even with two hours of labor (due mostly to rust on my from-Boston originally car) and extra parts cost to replace rusty clamps etc., the entire mod with shipping both ways was under $500.
