Yeah so long story short dynoed my car with intake and exhaust and hit 232 HP came back with ripps headers on and made under 230 ...pissed

akley88 · July 10th, 2011, 06:51 PM

that sucks. how similar where the conditions and was it the same dyno

maybe u should get an FI/C.... the most important part is actually tuning the car. your post should say "WTF, I'm a Dumbass"

tjh · July 10th, 2011, 08:06 PM

What is you'd elevation and was the reading on a corrected Dyno I made 210 whp on a corrected Dyno with intake and axel bac

FeaRlezZ · July 10th, 2011, 08:15 PM

^^ yes headers really increase the need for a tune. . FIC

20eclipse08 · July 11th, 2011, 07:19 AM

Same exact dyno. It was humid as hell fic is on the way and rj88 ..... Fuck off

akley88 · July 11th, 2011, 07:37 AM

these cars hate heat. the fic will help out alot

NitroGlisson · July 11th, 2011, 09:07 AM

Well that sucks...good advice on the FIC though. Kinda wonder if you had some codes going on and the car was in "safe" mode. When I put my headers on (OBX LTs) I immediately felt the difference. I didn't have a FIC at the time and have not finished installing the one I bought yet.

20eclipse08 · July 11th, 2011, 10:29 AM

Oh i def felt a difference and I am def getting the fic

TwilsonD7 · July 11th, 2011, 01:12 PM

It def flows better but were back to the whole back pressure debate...may feel faster but you lost power. Especially at the bottom end.

What he said, you added Ripps Headers, but you also deleted all cats
Post your dyno sheets if you can

deprydation · July 11th, 2011, 09:29 PM

What were your AFR's?

If you installed headers, your car will start running even more rich. This _WILL_ kill your performance. Get an FI/C and lean that sucker out to about 11.8-12.2 AFR and you'll be screaming in no time.

Also what you have to think about when doing headers or any exhaust modification is the natural physics of exhaust gas. From the moment that it leaves your cylinder as burnt fuel/air mixutre it is losing heat and expanding. When you up the size of your piping or delete things like catalytic converters you will see a noticeable performance gain but also have to worry about the rapid expansion and cooling of exhaust gas as it travels down your pipe to the rear of your car. Something you have to think about is how to get the best velocity of gas leaving the car but at the same time keeping enough heat to produce that velocity. Using a catalytic converter is the PERFECT way to reheat that exhaust gas leaving the cylinders thus keeping the velocity up of it and reducing the expansion to a level where it will flow better out of the vehicle.

It also depends on where you will spend most of the time in your RPM range. If you're at WOT about 90% of the time then a huge pipe will be beneficial to you due to the need for exhaust to be evacuated at high rates, but if you're talking about a daily driver here you have to consider keeping a good mix of the size of pipe and the flow rate with everything.

Just some food for thought. Hope I didn't confuse you at all.

pat_08GT_Spyder · July 12th, 2011, 11:14 AM

my RRE headers added 20 whp... same dyno and all...
what size are the ripp's again? is the piping bigger than RRE? just asking, never followed ripp to be honest...

dejectedangle · July 12th, 2011, 11:37 AM

I though ripps headers were for boost application only!!!

Then again what do I kno

2.5" for Ripp headers, which replace the stock "J" pipe "Y" pipes and eliminate 3rd cat.

RRE uses both intermediary pipes, and keeps the 3rd cat.

Daxenth · July 12th, 2011, 03:19 PM

i know i sure as hell felt a gain with RREs

OK, so same diameter then....
i run no 3rd cat, and i sure as hell did feel a solid gain too !!!!

deprydation · July 12th, 2011, 05:59 PM

Maybe he has an exhaust leak somewhere. That would explain a loss of power.

20eclipse08 · July 16th, 2011, 11:12 AM

K boys when I put these babies on there was a def gain. A couple days ago I was driving with no music and said hmmm I know when my girl sounds different. Jacked her up to find one of Tue three bolts that bolt the header to the pipe was gone. Would really decrease the power that much though. And I deleted all cats and put in a magnaflow highflow cat.

dejectedangle · July 16th, 2011, 12:21 PM

Do u have a magnaflow cat back?? That's my exact setup I love the sound how bout you.

TwilsonD7 · July 16th, 2011, 06:06 PM

FIC and tune, massive gains and exhaust will sound better.
