Hameeds got full replacement ones...not caps.
To me....these look like caps to fit over the OEM covers even though its being shown as direct replacements. I wish the seller would turn over the covers so we can see the backside.
Caps go for roughly $370 shipped on ebay....its cheaper in Japan but hard to get.

I have to say this is one of the best mods I have done to my car to date.
After my countless questions to RRocket and JBrady (thanks a lot guys for the patience you showed by not telling me to take a hike!
), I finally saved up enough funds (BDay present to myself this past weekend), to get my custom exhaust made.
I removed all the piping and all three resonators from the cats up front all the way to the L-tuned mufflers at the back. I replaced all of that with 2.25 inch mandrel bent pipes and a Magnaflow 2.25 inch stainless steel Tru-X pipe - (specifically this one http://www.autoanything.com/exhausts...A2672A0A0.aspx ).
Pros
The sound is just so awesome!!
The outcome exceeded my wildest expectations. It is very loud on WOT ONLY. That alone is worth the price of admission. On start up, the exhaust does not have a very deep note to it, however when you drive off and accelerate very hard, the exhaust note is pure music to my ears!!! It sounds like a more sophisticated version of a V8 mustang, however deeper than than a mid engine exotic car like a Lambo or Ferrari.
When cruising at city speeds or the highway and the tranny has shifted into 5th, you can barely tell the difference compared to the L-tuned mufflers by themselves (my previous only exhaust mod). So for example when I come home my neighbours don't know I am coming home. I was very concerned that the exhaust would be loud ALL the time, but that is not the case at all.
The exhaust gases are now flowing more freely (bigger 2.25 inch pipes and no resonators) and the X-pipe also contributes to that effect by creating a vacuum when one bank of cylinders pushes air out thus causing the other bank of cylinders to move its air out faster. The car definitely feels peppier, however I will dyno the car so that I can see what HP gains this mod made. I know I have not done a baseline dyno, however I will just take an approximate and average base number that others have done and use that as my base. Yes that is not exact or scientific, however I can't just afford to dyno the car so many times.
The nasty drone at 2100 rpm with the L-tuned mufflers is completely gone!
Cons
Some minor drone on part throttle at slow speeds (less than 30 MPH). Very minor. Not even worth mentioning, but I just wanted to share that the exhaust is not perfect that's all.
Now onto the pics.
1. Stock Exhaust
2. Stock Exhaust removed
3. First in-process pic with the custom Y-pipe and Magnaflow X-pipe
4. Second in-process pic with the straight pipes after the X section

Now onto the videos!![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
I would right-click on the links below and choose "Save As" and save the videos to your hard drive rather than trying to watch them as they stream as the first one is pretty big at 12 MB. I deliberately did not make it smaller just so that you appreciate the full effect better. Remember to turn up your speakers to full volume when listening.![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
When you watch the video, the start up does not sound that great in this video - the actual note of the exhaust is actually more deeper. I am not sure why the camcorder does not catch that. However on the second part of the video when accelerating away, it does a pretty good job of capturing the sound.
For those of you wondering how reckless I was doing this on my street - I did it very early in the morning when there was nobody around. I think the sound may have pissed off one or two people though. Oh well.![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
1. Start up, Drive away and Drive by

2. Drive by

For some reason I could not capture the "drive-by" sound effect very well. The car sounds much better than what I was able to capture here.
