Ok, i heard different stories about this. I want to do an exhaust soon after i do my downpipe. Some say its ok while others think i will run too lean. What do u all think?? I know someone with just downpipe and exhaust and he has no problems.

 

That should be ok. I've had intake, dp, cb, with stock ECU for over a year and I had no problems at all. I've boosted up to 15psi on a spike after adding intake, but there was no detonation, so I got a boost controller just to be on the safe side.

 

just to tell you, you double posted this topic.

It should be fine with just exhaust and DP...

One good ping on shitty gas and you'll be a rolling garbage disposal with a spoon in it. Get an ECU and richen up the A/F ratio before getting a boost controller.
