Hey I just finished installing my new Apexi Ws2 Cat-back exhaust system from the cat back. Now im burning alot of white smoke and smells like burnt wood. Before I installed the new exhaust the car ran rich as it was supposed to and ran nice. Smelt gas from the exhaust as normal but now nothing but white smoke and burnt wood smell. Any idea what this could be?

Heres my setup:

Car: Integra Gsr b18c1
Jackson racing SC kit. only on 6lbs
Walbro fuel pump 255
Stock injectors
obd1 p72 ecu stock
Cold air intake

Basically a stock setupd with minor upgrades. All I did was change the factory exhaust to the new one and now it blowing white smoke and smells so bad. I checked the spark plugs and they are black as nomal when rich. Please help me out if you got idea? Thank You

do you clean all the packing material out from your exhauset (if you had any). It took me about 30 minutes to get all the crap out of mine.

yes i did. Everything. I even took out the axle back to see it it was coming out of the motor itself and it still smelt like that. I called one of my friends whom which works with hondas alot and with what ive told him he may think its the head gasket. How could that be? Any ways I could check to see if it is the head gasket?

also want to mention that my pcv valve is just open and hanging there not connected to the manifold or anything else. But it never gave me any problems before.

compression check is usually a good way to see if it's the head gasket. Usually burning coolant has more of a "sweet" smell though.

nah this smell isnt sweet at all. It pure disgusting. Seriously smells like a pile of burning leaves. Theres a little bit of water coming out the tip. How else can I check?

this is all I did today. Before any of this happened. I jacked the car up unbolted the cat from the headers and unplugged the 2 o2 sensors and took the whole exhaust system from underneath the car and laid it on the ground. Then unbolted the stock cat from the oem exhaust system and bolted it onto the apexi system. then went to go bolt back the system to the stock headers then to the axle back and connected the o2 sensors back in. I had to unscrew them from the cat to heat up the bolts to take them off. But then put them back on hand tightend onto the cat and plugged them back to the harness. No o2 sensor light for any of them. Started the car and noticed the smoke and new wierd smell.

Just in:

I went ahead and took the system back from from the cat back and just left the headers on the car which were the same as before. turn the car on and it smelt fine I smelt fuel and all no white smoke actually no smoke at all. I just turned it on and ran it for like 1 min thats all just to see the difference in smell and man was it a big difference. Could it be that the new exhaust hasnt yet broken in? Could it be the new smell?

It's probably your exhaust. Mine smelled like crap after installing the exhaust and it went away about a week or so.

dude relax man. this happens with new exhaust systems. happened when i put my n1 on a few years ago. over-reacting much? its fine give it a week and the smell will go away on its own.

new exhausts have a coating of some type of oil on them (mineral i think) to keep them nice, shiny, and not rusty. it probably felt slick when you were handling it. that's probably what you're smelling.
