downpipe smoke
 

just installed my downpipe and i just took it on a test run .. only prob is its smoking .. is this normal? also its kinda loud .. would thermal wrap help with the sound? and and recommended site where i can get quality thermal wrap for cheap?

yes, thermal wrap will quiet it down a bit. i got mine from summit racing. i think it was the DEI stuff. also get the clamp type thing to hold the wrap on. i got the DEI clamp stuff and cut to fit as needed. i wrapped the down pipe while it was on the car. fyi - the down pipe will smoke like its burning after you put the wrap on.

as for the smoking, are you sure you got a good seal between the gaskets? try maybe using some new gaskets and some exhaust gasket sealant stuff.

is the car smoking or is the DP smoking?

is the DP mild steel or stainless, i know my mild steel dp is still buring the factory coating off and its flaking and interesting smelling

What DP did you get?
What are your other exhaust and engine mods?
Did you spray any paint on the DP?
What does the smoke smell like?

i have an apex n1 exhaust w/ a silencer on it .. i got apex intake as well .. as for the downpipe i dont have the slightest clue .. the thing is when i bought the car .. the seller had the exhaust and intake mods already ... and he gave me the downpipe .. but i just got around to putting it myself .. uhmm .. as for the gaskets i got brand new ones from malloy mazda .. it dunno how to describe the smell .. smells kinda like some chemicals .. thats the best way i can describe it

if it smells like chemicals its probally just the galvanize burning off.

Can you post a picture of the DP?

sorry i dont have a digital camera .. but i will post one as soon as i can im gonna have to borrow a friends .. oh yeah jonski thanks man i read one of your old post bout the rubber coupler between the ypipe and the crossover pipe .. that fixed my other smoking problem :)

rescue - dont sweat it. Im assuming you used some kind of penetrant on the studs of the stock pipe and did the same when putting in the new ones.

I think its the penetrant buring off - mine smoked pretty good for about 10-15 minutes after i started the car when the install was done. Took her for a nice, spirited drive, and when i got back, smoke was gone!

If your seal is not tight, then its exhaust. Just remount the pipe.

Good luck

Don't put wrap on a mild steel pipe - it won't stand the extra heat. The mild steel will quickly degrade and fall apart if wrapped.
