Here are some shots of the cool blue that my exhaust pipes are taking on.

graves4r6 · 05-07-2009, 11:24 AM

Very nice exhaust system.

Genro757 · 05-07-2009, 11:25 AM

Is it suppose to do that?

Cab5er · 05-07-2009, 11:27 AM

That is sweet!

Ti turns blue when you heat it. Thats why ti tips that are heated with a blowtorch turn blue.

That exhaust is pure sex.

Yeah, and make sure you wipe all fingerprints off, or you will have permanent prints after exhaust cools down. I had some permanent ones on my bikes headers.

The secret to cleaning Ti exhaust is WD40. I use it all the time on the Arata exhaust on my bike.

nkweisberg · 05-07-2009, 02:01 PM

you just wipe it down with WD40??? Including the tips?

That´s right - I did it on my bike and also did it on my M3.
It is real important, otherwise the prints will burn in!

yeah... what he said

Akara1 · 05-07-2009, 02:21 PM

Yup, WD-40 is the way to go on titanium. Been using it on the bikes and now the M3 exhaust.

yes...

exhaust looks great after the heat colors it up

BCMPOWER · 05-07-2009, 06:22 PM

That's cool, how long does it take to turn blue?

Adonislike · 05-07-2009, 06:26 PM

This is exhaust is sick but would like to hear it in out in the streets, not dyno

nkweisberg · 05-08-2009, 09:49 PM

The heat cycling during track sessions seems to make it more blue each time. Gets much hotter than it ever would on the street.

The sound on the street is totally livable. The only time it seems too loud is on initial cold startup. Driving around it's perfect. I'm a 38 year old professional with a very fussy wife even she's not bothered by it during normal driving. I've noticed it has a slight drone right around 2100-2200, out of that range no drone.

I'm in the L.A. area. Let me know if you want to hear it in person.

Nice!! I may look you up next week. I live a little north of LA but have to go down to OC, so this might work.
