Unfortunately it's not a simple bolt on swap. I do have an o2sensor code for 456 pre cat sensor. A good free-flowing cat won't affect performance, either. The content on this website is subject to change without notice. To make the temp sensor fit you need to file it down a bit, just enough for it to screw into the threaded hole in the manifold. Ask me how I know. Thx Luigi the confirmation helps lots.
A quick search on eBay turned up this header that is already sanded and painted. Also a few weeks ago i rebuild the turbo. Next, working at the right front of the cylinder head, remove the secondary air valve from the engine. Over time the high heat as well as contaminants in the exhaust melt or otherwise damage the ceramic matrix in the cat so that it requires replacement. Make sure you torque the knock sensor back to specs. You bought your 325i because its a reputation for performance and European styling appealed to your senses; so why would you be okay with second best when it comes to great quality auto parts? This time the rear flange is rotated 9 degrees out of alignment. Can ask him if you are interested.
And just replace with small resonators. To fix one of these studs, a torch should be made us of to heat up the nut and then the head so that they can be detached. I also noticed an exhaust leak sound coming from right beside the sensor which i supposed was a blown gasket just below the O2 sensor. I think cats should be kept, firstly you avoid the annoying smell without them and secondly they act like small resonators taking some harshness of the exhaust noise. I would pressure test the cooling system. Well, I can report success. All make some tests before assembling the entire exhaust line.
I have bad catalyc converters witch I'm changing next week. Enjoy your new car, it will really feel that way for a while until you get used to the power and want more. If they are in good condition power losses would be negligible. To connect the oil separator to the T-fitting I used an idle control valve hose 13-41-1-435-781. The catalytic converters are fragile and can be damaged from an impact.
Cant notice it when the engine is warm unless backing up with windows down and then its only a hint of exhaust. Figure 3 Next, working at the center of your exhaust, remove ten 13mm exhaust bracket fasteners green arrows. I currently own an E39, and I have a full muffler and resonator delete, and no power loss, nothing. I have been in and discussed, and they recommend loosing the cats and replacing with small Coby resonators. Was planning on oringing the block, but im not going to do this, first i will try to make 300hp. Used v-band clamps, so the downpipe or the tailpipe is easy to remove! Catalytic converters not included - off-road use only.
You don't need to remove the cats to getter a slightly better sound. On the last picture you can see that the compressorwheel is damaged, i need to order a new one More new stuff. But the one thing I got of value from them was a referral to a bmw independent We have been selling our M6x e30 swap kits for some time now but we are always looking for better ways to make the swap much much easier for customers. Wow if it is not one thing it is another. I took it to an exhaust place they welded it but no joke it broke off or melted off but bottom line is most of the weld is not gone. Should be able to build them for much less than the stealers.
Figure 2 Working in the engine bay, locate the top of the right engine mount. Install the engine mount upper nut and tighten. Where i work we have some small little turbos with exhaustflanges like the ones on the exhaust headers. Remove the nut from motor mount green arrow. People claim a torque loss under 4K rpm but I have noticed nothing but gains all across the rev range.
May 27, 2017 Followup from the Pelican Staff: Thanks for the additional info and feedback. First I can only monitor one bank unless I purchase another wideband but my setup will not accept logging from second unit. It's a bit of a faff to do as there are heat shields and suchlike in the way, but it does mean that a cursory visual inspection won't notice there's anything different. I have managed to remove all bolts and and the exhaust without damaging anything. I also needed to have the injectors refurbed, and I removed the swirl flaps so made sense. O3 330xi June 10, 2015 Followup from the Pelican Staff: I haven't done headers on an E46, but I recall the guys in the shop just removing the right side engine mount and bracket.
Figure 1 Working at the front of the exhaust system, remove the nuts that connect the exhaust system to exhaust the manifold green arrows. And supporting mechanisms can i use for this task? Is it difficult to remove the manifold Do I need to remove the whole exhaust system Also what if I snap the headers how do you then replace them There is this tappety noise that really is annoying the hell out of me. Car has complete maintenance history and even the orginele bill of purchase. How do I remove them? A lot of question I hope someone can help. The dipstick has suction too as opposed to air flow that would be blowing out the dipstick. Each manifold ducts the exhaust to a built-in catalytic converter. Intake temp sensor modified Before you install the new intake manifold you need to modify your intake temp sensor and install it into the manifold.
