I replaced my headers and added slp loud mouth 2 side exit now my truck is throwing every evap code o2 codes and p0010 & p0020, There is 17 codes total. The headers are obx without cats. Also added 80mm bbk throttle body and some brisk racing plugs with hot street coil packs. Truck run with all of that stuff fine but when i did the headers and cat back everything went wrong.
View 9 Repliesi cant find the dyno post but didnt the isf make more power with headers and stock exhaust?
View 6 RepliesWhy it won't work. copper exhaust coming off the headers. I have the ability to get it and bend it and how cool would that be copper duals. Why won't it work. If I bolt it right to the headers.
View 7 RepliesI got this hankering to re-do my exhaust while my truck is all dissembled. My true dual has been a mistake since day one. It never gave me that deep growl that I wanted, and I miss my old cat back. Anyway I thought of an idea that would give me my one muffler back with plenty of air going into it. Check out the pics, and let me hear it. I will be leaving the pipes coming out of the headers alone, that way I don't have to buy doug thorleys expensive y-pipe.
View 2 RepliesI'm having the well known situation with P0345, P0022
Replaced both phasers, replaced cam sensor, checked timing (properly aligned), assembled back still running rough and rattling, used 10w40 oil,
Complete rebuilt engine, we did head work new seals and springs, valves are straight I had it checked out twice for assurance. New pistons, new rings, new bearings, new oil pump and seals of course. If I disconnect cam sensor Bank 2 it works fine but still runs a little rough.
- Replaced one tensioner due to gasket wear.
- I was told to check on alternator ground (it's missing I know cause it got broken and I haven't replaced that ground that goes into the engine.)
- I also was told change oil to 5w20 and filter (Not FRAM), add some lucas and it should be the fix.
- Also told to disconnect the oil pressure sensor and it would fix the problem but it will throw a code for that.
- I haven't replaced the timing chains I feel they're a little loose but they haven't jumped the teeth, so I guess they're good.
- I saw in one thread to move a teeth on phaser giving me code bank 2 (moved one teeth back and then one teeth forward but it didn't work)
When I first rebuilt the engine I was having the rough iddle then I scanned it and it gave me the cam positioning sensor code P0345, then after I replaced it problem got fixed and code was gone, I was using the truck for 2 days with no issues, then the problem cam back with the two codes P0345 and P0022!
My 05 Passat, 1.8t keeps showing p0010. The cam tensioner and camshaft sensor have both been replaced, the oil pressure is correct but it keeps showing the codes with the CEL on.
View 1 RepliesI thought these things were bullet proof. I have 2 sets of recently installed ceramic coated headers and both sets are getting a rusty haze to them. One is a set of cast iron manifolds I got done at Jet-Hot and the other are from Ford Racing. Is there a polish or cleaner that will bring them back yet not damage the coating?
View 1 RepliesLooking for aftermarket headers for a 2011 f250 6.2l gas job. I have the famous leak and I want to put something in that isn't going to warp. I was told shorty headers typically match up with the stock exhaust. Eventually going to put in a cat back also so true shorty headers would be sick.
View 14 RepliesDeleting the cats from the stock headers ? would there be any power gain or loss ?
View 14 RepliesHeaders will probably be the next mod that I do to my F, I have read a good bit about them on here, but no one really says anything about how they are doing long term ( any issues from heat on engine bay plastics after years of use) or how the coating holds up after years of use as track or DD or just anything else that seems to be an issue over time after being installed.
View 14 RepliesI have a lx570 2013. I bought Doug Thotley's Longtube Headers. I haven't install yet, But I am about to.
I need to get my self a set of mid pipes that would hook directly my Doug Thorley's LongTube Headers and into the oem cat back.
I looked around it I found this set. Link Below: [URL]
Also, a friend of mine of mine has a LX570 with JBA long Tube Headers (Titanium), He also wants a set of mid pipes to fit directly to his Jba long tube and into his oem cat-back.
PPE Engineering has been getting lot's of inquires from us ISF owners about the feasibility of making an Equal Length Header for the ISF similar to the one they make for the RCF. Since I am a past customer, live nearby, have another vehicle and am a pretty nice guy they called and asked if I might be interested in having my car test fit for Equal Length Headers.
While discussing this with them, I suggested that if modified RCF Headers wouldn't fit, maybe they could accomplish the equal length task by using long tubes. Well, it seems that RCF headers will in fact fit in an ISF, and the headers they built for me were also Long Tube. How sweet is that? But, the EL, LT headers must be used with the PPE Exhaust due to the exit point of the collector.
I went for Dyno testing yesterday, and it appears I lost 7HP at the top end and gained only 1.5 lb ft of torque at the high end. I also gained grunt at the bottom. My Seat of the Pants tells me the car is faster.
I don't know why it ran out of breath at the high end. Nothing else has changed.
PPE Headers
PPE Dual Mode Exhaust - With HiFlow Cats
Takeda Intake
As far as sound goes, in the cabin with the exhaust open, the drone remains in the same area (between 1900 and 2100 RPM) but is much lower in volume. I can now carry on a phone conversion (with bluetooth hands free) with the exhaust in the open position. The volume level does increase, however, when under acceleration through that RPM range.
Now the ISF does not have a lumpy engine by any means, but it idle with the old headers, the sound (both inside and outside the car) had a sort of lumpy growling quality to it. The sound is now very smooth, again inside and outside. The harmonics seemed to have changed.
Edit - My wheels and tires have changed. I'm now running RCF wheels with larger 295 vs 285 rears, so wheel weight is up a bit!
how much HP is there expected to be with adding high flow cats?
View 14 RepliesI had my local race shop install my new PPE headers and how I have a rubbing and grinding sound while taking right turns. They have had the car for a few extra days and they say they cant seem to find the cause of the problem. It rattles on a pot hole, it grinds on right turns and sometimes vibrates on highway cruise control driving.
View 14 RepliesI replaced my knock sensors on 2004 5.4L and now it will not idle without me keeping foot on gas. Idles down to +- 450-500 rpms. If I hold down gas pedla seems to run smooth. What to check to fix this problem?

View 1 RepliesI have a 2004 F150 5.4L 2WD auto. I had the cam phasers and timing cover done at the end of 2014 and the truck was great. Back in december, I parked the truck and when I started it the next morning, there was a horrible miss. I left it parked a month or two, then tried starting it up last week. Nothing.
So I had it towed to the shop. They found the starter was bad, and the only code it was throwing was P0341... Cam sensor bank 2. I had it towed back to my house, replaced the starter and the grounds and fired it up. It had the worst miss on the planet and died shortly after being started. I replaced both cam sensors, and now it starts right up and runs... but still has a bad miss.
I used my scanner and its still throwing A P0341 code almost instantly. It sounds like a bad miss that slightly gets better when you give it gas... but its not throwing any misfire codes or anything.
All I did was cut off the straight section of tailpipe and install a 2.5" inlet, 4" outlet exhaust tip. It sounds a bit deeper at idle and a little louder when I rev it, but when I let off the gas it pops pretty loud.
I remember hearing popping on decel on videos of trucks where aftermarket exhaust/mufflers were installed, but not just from a new tip.
Was looking for a cat back exhaust for my 04 FX4 and was curious if they involve any welding or just strictly bolt on?
