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.

get some sound clips posted!

SS_Firehawk · 02-19-2012, 12:13 PM

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.

SS_Firehawk · 02-19-2012, 01:17 PM

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

Here are a couple links to the Dyno pulls. Still waiting on one more video to upload.

Fixed

Great numbers and nice vid! repped!

Edit : not to mention that you possessed one of the best JDM cbe, good growl too!

So this time it is throwing a misfire code. It was P0300. I don't see any definitive fix action for it besides just drive and wait or get a tune. Quick note, the SES light always popped on while I was driving. It seems like most of the others have it pop on during initial startup.

SS_Firehawk · 03-02-2012, 03:58 PM

Kinda seems like I'm talking to myself or blogging or something, but just throwing out as I see it. I cleared the P0300 code and came back again. So I'm thinking the only way to get rid of it is a tune. That might take a while to get together. I did have my AFR checked during idle. When it dropped below 900 rpm, it went to 13.5, and when it revved up between 900-1200, it goes to 18 and sits there till the next stutter back down to under 900 rpm. From what my mechanic is telling me, a good AFR at idle should be 14.5, anyone know more about this?

rxdo · 03-02-2012, 05:19 PM

From what I have read that seems a little lean,18? I would go get an uprev tune. Also can you try to repost the video it doesn't seem to be working, thanks.

SS_Firehawk · 03-02-2012, 07:14 PM

I'll repost all links to the first post.

SS_Firehawk · 03-09-2012, 12:21 PM

So back to the rasp issue I have... Should I remove the cat and put on a resonator instead? It kills me when the car sounds awesome, then rasp rears it's head and sounds like a pissed off chainsaw. It would at least give me the option to run cat or resonator and definitely cheaper than another exhaust. Idk if it's worse inside the cabin than it is outside, I just don't want it.

tranceformer · 03-09-2012, 03:29 PM

I would keep the cat on the xyz pipe.
