RPI GT Catless with Stock Exhaust- No CEL?

MGZT · 10-03-2009, 05:05 PM

First of all, yes it's freakin loud with stock exhaust! low rpm is quiet but it screams at higher rpm

... yes, I do feel the power also!

My question is, I've been driving it for around 60 miles now and No CEL...
Is that normal? Did I install it wrong?

TIA .

Ahh I see... Thanks, I thought I got lucky for a sec. haha

I can't imagine those people with full catless exhaust system.. how do they talk in the car?

How do you like the sound? I tried the same setup and it was the worst sound I've ever heard coming from a car. Very raspy, misfires, etc. Was this your experience?

Replacing your cats while keeping the restrictive OEM muffler makes no sense to me.

PLUS 1

Upgrade the rear section as well!

It took my car 800 miles before my CEL came on after removing my primary cats.

RPi and OEM sounds like a shitty motorcyle, I had to rock it while I waited for an exhaust

Amen! It does sound pretty crappy

The plan was to gain a little hp with little change to sound but ... didn't work out that well.

are you talking about he CEL in your dash or the o2 error code if you use a BT tool to read the car?

CELs will always pop up. Be patient
