Who coats?

 

Hi Tech, mainland I'd go with Swaintech, only because the other major coater "lost" my manifold when I wanted it coated. I'd only coat the outside. I wouldn't want flakes going into my engine.

San

 

Looks like this must be the 'equal length' Fujitsubu:

 

sorry off topic how much would it cost to coat downpipe at Hi tech and wheres Hi tech at? i know its at industrial place but where. i been thinking of bringing my rims there to get it coated.

 

Unequal length.

 

I perfer to ceramic coat both inside and out w/ a 2000+ deg product (not all coating places can do this). The danger w/ coating just the outside is that more heat is retained in the metal and welds which could lead to premature failure.

However, since your uppipe has a flex section I wouldn't coat the inside (like San suggests) as the flex could cause flaking of any internal coating.

Note: Hi Tech is in Campbell Industrial Park just of the main road going it. They're listed in the phone book.

 

Dean, I'm not disagreeing with you, because I don't know shiite from Suni-ola, but I found this (cross-posted from tech.)

Hey Pat,
I have the same concerns regarding coating internal parts. At this point I really haven't formed an opinion on them for a daily driven car. I've had a lot of exhaust parts coated and have always sent them to the mainland. Hi Tech does a good job powder coating but for ceramic coating I send stuff to Performance Coatings (http://www.performancecoatings.com), I have also used Jet-Hot a bunch of times but have been very pleased with the price, quality and service of PC.

edit: I use a combo of exhaust wrap and ceramic coatings to keep the heat in the pipes. Exhaust wrap alone can contribute to corrosion of parts so the ceramic coating serves a dual purpose of insulating and protecting the metal. There is a risk with internal coatings on any pre-turbo part. Failure of the coating would send pieces which could damage the turbo (turbine side. the intake side and motor should be safe) Any pre-turbo coating had better be good to 2000+ degrees. FWIW my uppipe is coated inside and out w/ the 2000+ deg black satin coating from Performance Coatings.

 

Dean, excellent website and thanks for stating your experiences.

Since I have no experience, I'm probably going to do as you've done.

 

Dean=smart

He's got a mechanical engineering degree from Univeristy of Hawaii and a Master's degree in Aerospace engineering from University of Colorado.

And he'll flame you like he did to that nOOb in that other thread!!

 

Are you gonna supercharge something?

Where, Where?

...and I already knew that about the MR2Suby guru.

I know many folks' online personas better than I know them personally.

 

Here's what they look like now:

 

Nice Pat, I saw them over on Nasioc a few days ago. I need to pic up some equal length headers soon.

 

wicked!
