I just installed my Apex'i WS tonight and after running it for a little while, i smelled this burning sugar smell coming from the exhaust. I couldnt figure it out. Maybe the ceramic coating or whatever baking on or whatever because its the first time its been heated?

Also, i love the look and the quietness. I still can't hear anything but my damned intake. that thing is loud. Right when i installed it, there was a slight rattle, but it was just a heat shield, so i took it off. Fitment was excellent and everything looks great. Everything just seems smoother now.

Now all i need is a high flow cat and header

 

i used to have this cat back setup in my Si coupe...don't worry about the smell...it will go away in about a week or so...i think it's the anti-rust material in the piping or something...

 

its just because its a new exhaust dont worry about it. Like acydphryck said it will go away in about a week

 

I always thought it kinda smelled like marshmallows

 

haha..... i remember that! i was woundering the same **** when i first got my WS... thanx for the memory...

 

damn i still remember when i got my ws, all i coudl hear was my motor, damn i love that exhaust.

 

Yea, smells like burnt marshmallows....or burning marshmallows. It was funny, we were driving and a friend of mine was behind me and he acually asked his passenger what that pleasant smell was. Thought it was coming from the Bi-lo bakery or something!

Thanks for the info tho guys. I love the exhaust, kinda wish I could hear it a bit more, but maybe when i get a high flow cat and a new header the sound will get a bit louder and nicer. So far I love it.

 

Yeah, that sound is normal. I remember when I first put mine on, I thought I had messed something up or something was burning that wasn't suppose to be. Mine went away in a few days.... but thanks for reminding on how it smelt

YEAH marshmallows i couldnt figure out what that smell was

i just installed mine too, and I it as well

 

I thought I had left a wrapper on somewhere, and was burning it off...I love my WS...and if you paint it black, you're a dope

 

How many people experienced the gas tank rattle?

 

mine did until I beat my gas tank in w/ a ball peen hammer, then it rattled against my brake line until I relocated it...make the car fit the pipe, not the pipe fit the car

 

It's the gaskets setting in, it just takes some time... Smells like eggs huh?

LOL Some real shadetree stuff. Can I bend the hangers on the muffler to get rid of the rattle? Or do I have to have them relocated? It really pissed me off that I paid 350 for the "bolt-on" exhaust and it still doesn't fit right.

not gas tank rattle but, heatshield rattle when we installed it on my friend's car. i used a dremel to cut that portion off of the heatshield.

 

i just took the entire heatshield off that was rattling

94 Civic DX coupe and yes it's the gas tank and it's quite annoying.

 

use the peen end of the ball-peen hammer and do a little metal work...

 

when theay mandrel bend the exhaust piping, it requires a light coat of an oily substance that is burnt off as the exhaust pipes heats up for the first few times.

 

how do you all locate exaust rattles? jack it up, get under it, and have someone gas it?

You listen carefully and look under the car to see where it hits. My WS smelled the same way, it's part of the "break-in" process. I also had to bend the last heat shield because it was hitting the piping. Also, at times my short shifter hits the piping which is why I'm going back to my stock gsr shifter.

 

for my friend's situation, it rattled under idle so it was easy to pin point the rattling. also, i just got under the car and shook the exhaust piping every which way to try to simulate the rattling under real world conditions to see where the rubbing occurs.

 

i got on the gas till about 3k where it rattled then my friend looked under the car with his mag light (this was 9:45 pm) and tried to see it...he saw where it was close to a heat shield, so he put on a glove and put his hand on the shield and held it out of the way....thats it.

then just unbolted the heat shield and pulled it off

 

Did you notice any performance gains after installing the exhaust, I've been thinking about getting the WS for my SI?
