Put both of them on, sorry i should have been more specific. It may take a few days for the CEL to go away, even try to disconnect your battery and let it sit for like 30 mins, then do a TBA. Also, your CEL may go away, but their will still most likely be a code thrown, but no CEL with it.

 

good news!!!!!!!!! today the CEL went away with only one of those plugs

 

can you post pictures

 

I'll take pics of it tommorow in day light but my pics are always so tiny so excuse them

 

thanks anything will help. was it successful? did you get any more power out of it? hows the sound

 

the sound is very nice, the turbo kicks in faster and you can hear the turbo spooling, I feel most of the gain on the high way

 

did you notice any lose of low end torque?

 

very little on take off but at the end you defenatly make up for it, trust me its worth it

 

Do you have anything else for exhaust, like a cat back?

Well my butt dyno felt that the test pipe added the most of all the pieces of my exhaust system i installed. You may loose low end torque but the turbo spools ~600-700 rpms qicker giving you more power quicker.

 

I have no cat and exhuast made by pro 1 I had this exhuast on my 2003 tiburon so its old but sounds nice, my exhuast is dumped out with dummy tips in the back but I don't like the set up because it looks shitty and too loud inside the car because muffler is right under the center console
