Welcome home!!! Congrats on the new mods but next time you dyno do the pull in 5th thats the 1:1 gear in our cars. Great ride and lets see some pics!

Thanks! I thought so, but they were hesitant. even after I told them I thought it was the 1:1. Now is it going to hit the speed limiter on 5th on a 6 speed? How much of a difference would that make btw? The pulls between 3rd and 4th were nearly identical. My next pulls, I'll do one 4th gear run for an apples comparison, and two 5th pulls.

So I dropped my car off at the shop to get the exhaust put on. I dropped it off at 5pm and they finally got the factory headers off at 11:45 pm. The car should be ready in the morning. I feel like its the day before Christmas right now!

I picked up my car earlier this evening. I'll post up videos and pics tomorrow. I did a dyno run as well with identical conditions. I enjoy the exhaust note, but there is a bit of tinny raspiness to it sometimes as well. It is still being broken in and heat cycled, hopefully some of it would go away. There is also some hissing sound, which isn't so bad. It's something that is almost expected with LTH's and free flowing exhaust. Overall I'm very satisfied with the performance and mostly happy with the sound. It's quiet at idle and cruising, and load as hell when accelerating.

Sorry for the delay, I'm trying to figure out how to blur the license plate on one of the videos. Anyone know how to make it work?

NVM, I just redid the video for now and taped a piece of paper up just in case. I'm uploading the videos right now. Will post when complete.

Adding the Dyno sheet for now. Going to take a while for those Vids. This was on the same dyno under the exact conditions. The car is running with a CEL and no tune as well. Installed parts were the PPE LTH, XYZ Y pipe & cat, and Tanabe Medallion exhaust.

Here is the link to start up and revving, just completed. http://www.youtube.com/watch?v=0-t_v...ature=youtu.be

Thanks! I have the last video with my Wife and I driving a few miles.



I tried to get all the different sounds from the exhaust in the video. I implemented slow acceleration, deceleration, hard acceleration, cruising, idle, and tried to show some of the drone as well. I reset the battery to clear the CEL and the idle definitely smoothed out. There are still a couple things I want to check out that are making buzzy sounds.

So a couple questions to help cure my ignorance. There is a vibrating sound coming from my driver side engine compartment that I generally only hear when I turn the wheel and accelerate, only at low speeds such as a left or right turn at an intersection, and not all the time.

Now this raspy baseball car tin sound I hear... I only hear it again when accelerating with generous throttle. I don't hear it when I'm lightly accelerating, with the exception of 4th gear. 5th and 6th is kind of hard to hear with wind and ****.

Do these sounds sound like something is making contact with the exhaust or is it just inherent with having an exhaust this opened up? I can try and make a vid if you guys like to capture the sounds I'm hearing. Everything else sounds magnificent... It burbles, has a deep throaty sound, quiet at cruise and idle, sounds pissed when I'm on it. I'm really happy with everything except what I described.

Thanks guys in advance.

Bump for help. My CEL keeps popping after these headers. Anyone know if this is supposed to happen with PPE Headers?

So what gains do you all think I should gain with the AEM CAI , M370, NST pulley's, and Uprev tune? I already have everything except the tuning software. I may be optimistic, but I'm hoping for at least another 30.

I hate to be negative nancy but don't expect too much. I'm going to guess with all mods, 40 to 50 whp above your baseline.

At the end of the day its still just a naturally aspirated V6.

So when I got my headers installed, that computer hookup wasn't working and couldn't check the SES light. Come to find out, the fuse needed reset. So after I did that, I was able to get a scan. Both bank 1 and bank 2 o2 sensors are not communicating with the ECU. I'm bringing it back to the shop so they can verify their work and troubleshoot the issue. Also does anyone know if Uprev allows you to play with those sensors at all? I was going to buy it when I installed the rest of the stuff, but if this issue pursues, I might have to get it early. Any suggestions?
