Pics of K&N, modified airbox, and stock exhaust

Since there's so much talk of the muffler, resonators, and airbox, I thought I'd post pictures of mine, so those who haven't started tinkering with their RTs know what we're talking about!
I modified the stock airbox by "ventilating" it with a hole saw 8) , taking INTO account heat sources for the best balance between airflow and inlet temperature.

Here's a shot of the stock resonators (20lb. each!) behind the bumper:

And the suitcase muffler (25lb.!, with a key beside, for size comparison):

The air silencer (3.5lb.) outlet INTO the airbox:

The air silencer inlet:

The air silencer restrictor inside:

K&N filter in place (I didn't modify the airbox lid):

overall, how do you feel about the end result?

yeah, how do you like the effect of your air box and what did you put in the place ot all that missing exhaust?

damn thats alot of exaust crap eh?

I like the effect of the airbox! Plus that fact that the mods only cost me $5 for a hole saw and $40 for the filter through Jeg's. It definitely pulls harder FROM the midrange on up, and the revs don't slow, even up at redline.
I put Magnaflows in place of the suitcase muffler and straight pipe in place of the resonators. I love it, and so does my wife!

WTF! The stock exhaust is only 2 pieces. The right side rear muffler is welded to the suitcase. Dumb!

**billapex** · 09-15-2004, 01:06 PM

I know! Isn't that weird?!?

I would've thought that there would be a flange on each tailpipe after the suitcase, but, oddly, only on the driver's side.
I LOVE AIR HOCKEY!! :lol:

when the DC enguneeeers ordered exhaust they must have SUPER sized their order!

billapex how did you get the silencer out? I was looking at mine today and it looked like you have to either remove the inner-fender well or the bumper. Or both!?

Just wondering if there might be a way to "ram-air" something in place of the silencer. Looks like there is room. But I'd like to know how to get it out first. Thanks!

The fender liner can stay in place. I just undid the fasteners securing the driver's side of the plastic undertray, pulled it down about 12", stuck a ratchet in there with an extension, and undid the one bolt holding in the silencer. It slid right out. Super easy--took about 20 minutes, and that was in the dark. (Yeah, I got the itch to do it right now. :lol: )
