IndyC3

Here is my C3. Ive had it for 10 years now. Almost to 93,000 miles. Made 1 year in green, black and pewter. 4400 total. LQ4 engine http://www.silverado...e&do=view&id=61

My 1 7/8 American racing headers went right in. I didnt have to modify the truck or the trans to exhaust mount. I didnt need any extensions either. The only thing i had to do was tweek one hanger a little in a vise to get them parallel. My tail pipes both ended at 3in straight tubing to mate to a custom exhaust. All in all it went smoother than expected. I helped my brother install some in his Jeep srt8 this weekend-Now that was a major PITA!!!!!

No performance gains. Stick with the stockers they work just fine.

This looks like it would be a great addition to any SS. You can get the trans controller with it also. http://www.tciauto.com/products/6x/

Congrats! If your in cali you gotta go to in-n-out burger. Also if you like mexican there is a El Torito on Redondo Beach pier (south of santa monica) that is pretty good. Have fun.

When I gutted my cats I didn't see any improvement in times. If you cut them out and put a tube in it's place it should be better. Since then I have gone to a headers- no cats set up.

I use a ZEX sysem. With a 75 hp shot I dropped 1 second in the quarter mile. The kit is really easy to install and only has 3 wires: 1 to a switch, 1 to a ground and 1 the a TPS wire. It learns where full throttle is. A window switch could be added also if needed. 2 thumbs up for ZEX!

That doesn't sound like a sending unit. Sounds to me like your gonna be pulling the oil pan on that bad boy to change some bearings.

Thanks guys!

Hows the install coming along?

I looked in the inlets and there was an x right at the entrance and yes there is a y at the outlet. Its funny because I dont see anything on their website about that muffler having an x in it. I took the front muffler off but now it is too loud so I'm putting it back on. If there was only 1 x in the system it would probably be perfect.

We'll guys its quiet. Too quiet. I'm taking the front muffler off tonight. One thing I was surprised to see was that the rear muffler had an x in it when I cut the tubes to reposition them. At least it doesnt have any drone at this point.

I'm jealous!!

The tailpipe is 4 in. I saw how you had to fight some noise thats why I'm doing this.

I saw what Moregrip did with his exhaust a while back. He used 2 mufflers after an x and then a dual 3 in/out and dumped it at the bumper. I have the mid pipes on now and it still sounds like a Top Fuel car when they first start on alcohol maybe louder.
