Default I'm new. Try to help my brother

Hey Guys and Gals,

I am new here. I am doing some research to try and fix my brothers WRX. I am posting to say hello and to get permissions for the WTB section of the site.

Car has been great. We have something like 140k on it. Had it since new in 04. It has some basic bolt ons, Perrin DP, HKS Hi Power cat back. I believe he has an intake and an HKS BOV as well.

He has been blowing 02 sensor signals since the DP and we are looking for a way to fix this. Anyone know of any cheater mod to stop the signal?

If not, I am looking for the OEM Exhaust for on 04 WRX from the header back. Finding gasoline alleys to do shady inspections has become tiresome.

Thanks,

NexxWins

Has the 04 been tuned for the DP?

I do not believe any modifications have been made to the mapping.

The DP should really be accompanied by some sort of engine management to help prevent detonation. Throw your BoV into a lake and thank me later. As for an '04 stock exhaust I may have one for you in the very near future but it's currently bolted to my turbo. =p

Don't look into cheater mods, get it properly protuned and then and ONLY then, smoke cigarettes.

You can search on here for the resistor mod for the EGT, but I'm not so sure if it works the same way for the O2 sensors. I'm sure someone will chime in shortly but most will recommend it get properly tuned for the difference in flow.

I do not believe that the goal is to hang onto the car. It has had a great life. I either want to leave it how it is and use it to Rally X or I want to fix the CEL by replacing the parts back to stock so it can be inspected and sold.

For years we have been replacing the 02 sensor to pass inspection and then it fouls in a few days to a few hours after the inspection.

Please keep me updated on your OEM exhaust.

Are you talking about a reflash when you mention tuning?

Someone please correct me if I'm wrong but as far as I understand it, whenever you swap out the stock downpipe for a high-flow catted or non-catted downpipe, you NEED to get a tune. This is why you keep blowing out O2 sensors. I believe the only way to solve your problem is to get a tune, or install the stock downpipe. You risk damaging your engine running your car as you currently have it.

I don't know enough about BOV's (other than most people think they are garbage) to know if that's contributing to your problems as well.

140k plus on the car probably 120k with the exhaust this way. What ever damage is/was going to happen has probably been done.

Anyone care to share how/where/what to tune? What will tuning (I am assuming fuel mapping) do to stop us from blowing the 02?

I very much appreciate the help guys.

I don't think (no offense) anyone on here is going to be able to tell you how or what to tune.

You need a tune for the Dp, or have a tuner edit you CL/OL tables in the ecu. 04+WRX's need tunes for a dp. Or else it make the car run leaner and is very bad for your car. Honestly get a tactrix cable and you can do it yourself if you plan to auto x it only.

post ur vin so we know this car was ran without a tune with a dp..... so the buyer doesnt make a WTFBBQ thread here. I suggest a leak down and at least a compression test.

yeah its because tuning is work. You can figure it out by going to romraider but they caution against it because people have taken advice on thier tunes then came back like wtf my motor is shot.

I don't think that's a good idea.

One more thing. If you see an "UncleScotty" post something in here, just ignore whatever he says.

Who should I ask or where should I look to learn this information?

Scotty is banned from the Newbies forum. Whatever he would say in here would actually be what MOST of us who have been around for awhile are likely thinking.

OP, whenever you change out a downpipe on these cars you NEED a tune. Along with an intake. BOV's are also junk. While it's your brother, this is a classic example of why you need to RESEARCH then BUY parts.

You wouldn't need "shady" places if you did research on the subject. Your only 2 options to turn off the CEL are essentially a stock downpipe OR tuning.

Read everything you can and ask a lot of questions. Personally I don't recommend tuning yourself but if you're not too worried about the end result of blowing a valve then it's a good car to test and learn on.

You mean the threads posted above? haha

Read the FAQ's first. Then fill out your profile so we know what part of the country you're in. Depending on where you are, myself, or some of the other members can recommend some of the local tuners that may be near you.

I could have you an oem exhaust in roughly a few weeks. (depending on how far away you are.)

Ya know, a long time aqo, Scotty gave me an earful (or eye full) for posting some stupid **** here. He forced me to take a step back and realize I should search before posting stupid ****. Banning him from the newbie section wasn't the brightest idea we've come up with, IMO. He's blunt, sure, but he does make newbies think before they post the 135,000th iteration of "which BOV should I get?". Or at makes them think twice about asking something else we've see 135,000 times.
