So i have an 04 rx8 gt with about 140,000 km's on it.

straight pipe (just had it installed), exhaust, intake. also running a pre mix (about 6 ounces per fill of 2 stroke synthetic)

5w30 oil. just had an oil change.

I noticed a bit of "haze" in my side mirrors behind me. it is running rich right now, need a tune.

I asked a friend followin me if my exhaust was smoking, she said ya. i said what color , she said a darker color.

Anyone know if this is normal? its not super thick, but visible on a hot day still.

Any help is greatly appreciated, thanks!

Yes, you can smoke a bit. If you get puffs of smoke (white or blue) on hard, in-gear, deceleration (like downshifting to 3rd), then it signifies a problem with the coolant seals / oil rings and you are looking at an engine rebuild. Faint smoke on full or transient throttle is not a problem.

(We have lots of emissions, and removing the cat stops cleaning them, and they can be visible)

I have also noticed that when experimenting with certain premixes I have found that some of them smoke more than others, especially the Marine TC3W stuff.

thanks guys, i figured it was normal, cuz there was definitely a power increase. and she's running fine, but i know a rebuild is around the corner in the upcoming years anyways.

Weren't we supposed to stay away from the Marine TC3W stuff ??

Yeah, it can be bad for cat converters. If you don't have a cat it's not an issue but ideally you want to use a JASO rated 2 stroke.
