Man was I crushed when I took my ride out tonight for a scan and saw the same amount of KR after installing the 3" D/P as before. Actually there's even a little more, It peeked at almost 7' KR as apposed to 6' and it starts showing up around 2000 RPM's (Under WOT) whereas before it was 3000+

Edit! Here's the scans for those interested...

SCAN1 - Before D/P Install
SCAN2 - After D/P Install

Other things I notice about the Downpipe is that the car definately feels a little diff. Hard to explain exactly but more "rougher". I don't know if the car is any faster, it may be my imagination but it feels potentially slower now. I pinned it from a stand a barely spun the tires where before I could spin them for 3 blocks if I wanted (Granted I have new tires now which would have some contribution to that).

All in all, I don't know if it was worth the $375.00 Installed and I'm still stuck fighting the KR Issues. Not sure what to do next, if anything at all, live with it maybe?

Cheers All!

I'd say trade your GTP to me for my SE, no KR in the little 3100!!

Crap, that sucks.
I noticed improvement right off. I can't floor it wide open from a standing start anymore or I'll roast the tires. I have to gun it to half throttle and roll on to a full throttle.

I would suggest maybe trying a different plug. Maybe a copper core plug. Herc can elaborate a little more on that. He had a good post not too long ago about plugs.

...I wonder if maybe somehow the cat got knocked around and glogged up? I don't know I'm just trying to think of anything.

Hello,

You might try disconnecting your battery for about an hour and make another run.
Be sure to take it easy the first few miles, work your way up to aggresive acceleration.
You will see a few disturbances on your scanner as your PCM relearns.

Later now,

Reset the computer... that might help things.

Yeah, i was wondering about trying new plugs... man, my skin just finally grew back from the last set I changed

I'm considering a throttle body spacer (albeit it will be little if any help i'm sure) I suspect the 91 octane here doesn't help, we have 94 now at one station but it's ethanol blended and seems to run worse then 91, I scanned it at the same.

I'm running out of ideas really, my car bra should be here at the end of the week maybe that will help HAHAHAH (It's for highway driving only all you car bra haters (like me)).

So...

1. New plugs (Autolites)
2. 160 Thermo (Drilled?)
3. Throttle body spacer (Maybe)
4. Put my old 16" tires back on so I can spin for 3 blocks and feel good again

Cheers!

Excellent, let me try resetting.. Thanks Guys, Never though of that but now that you mention it, I did read something like that before.

Thanks!

I hate them too... I keep mine in my trunk. Did you get the mirror bras too. They fit real nice.

My bra has been collecting dust for 9 months. I hate trying to clean the pine tar, berries, etc off of my hood when I remove it.

Yup, i got the mirror bra's aswell. We'll be doing about 4000 KM's on our honeymoon through the Canadian Rockies to the west coast and back, so I figure it would well be worth the investment.

Thanks for the tip Austin G______T ______P!

Just added the actual scans to my first post in this thread for those interested..

I've also unplugged the battery and will run more scans tommorow night

Word of advice, since you live in Canada and I KNOW it will be colder than where I live you should remember to keep your old thermostat if you get the drilled 160. My car took forever to heat up with that thermostat and stayed cool the whole time. Had to switch it back so I could get heat in my car quicker.

I hate my_____new_____name.

Flip your front sway bar upside down. Chances are you are experiencing falsk KR from the DP banging against the sway bar.

I second the false KR theory.
