Those are purdy -I think if you are tracking/racing it makes a lot of sense. I do not think for the street use it is necessary although I still sent my headers to Swain and I will be only using it for the street. Supposedly from locking in the heat you can optimize the HP gains but whether that has been proven I do not know.

I checked my notes and the most recent complete exhaust system we sent was about $750 to have coated; it was manifolds AND mufflers. Someone asked today as to whether or not this is necessary for the street and I told him that it's all done to try and reduce engine oil temps. You're essentially trying to dissipate the heat radiating into the engine bay by coating things. you will run a bit cooler if you don't have cats but the reality is that it's the sustained RPMS from 6K to 8K RPM that are what create the heat. For the street, you will be fine BUT if you're looking to reduce engine bay temps, this seems to be the best way.

Someone asked this earlier and I don't think it was answered, but where does the heat go? It has to go somewhere. Hotter exhaust gasses?

jmartpr

Some is retained inside the exhaust system but most is expelled out back (yes, hotter exhaust gasses). The theory is that by containing as much heat as you can on the gasses you increase exhaust gas velocity. You also diminish considerable radiant heat into any surrounding area and air/space.

These just arrived at the shop! They are off now to get ceramic coated and will be fitted in 2 weeks time!

FS: Cargraphic Racer X Exhaust & Flex Pipe (no headers). For all your track junkies, this exhaust system might suit you guys best. I decided to just stick to the race headers with pse for the street. The exhaust and flex pipe are brand new never installed. You can have it for what I paid for at msrp and I will cover the shipping to you here in the U.S.

UPDATE: I have asked Cargraphic for a detailed update as to what has shipped and what has not. We also have a personnel change in the office which has left me to manage both sides of the store but Monday I have a new employee starting who actually comes from a well known vendor who sells on these very forums. Help is on the way folks!

@Cooperyau - I found a buyer for that system and have a need for it and I have a deal to offer you for a credit on discounted upgrades for the GT4 to drop lap times on 495!

cooperyau

Thanks John. I will pm you offline to coordinate.

In theory, ceramic coating may even help keep tranny/diff temps down a bit too.

I was going to ask when my headers would come in. I'll probably send them off to get coated too. I'm going to have the lightweight flywheel and Guard diff installed when I install these headers.

UPDATE: Spoke with Cargraphic this morning, and they are expecting all units to ship in about 2 weeks.

i will stay on them as i realize it's been 3 weeks. They wanted to do the entire group buy order at once in manufacturing and i agreed because this way we don't have to determine a pecking order for shipment. i appreciate your patience. i can have Wray ping them again next week. For those that don't know, we have a new sales person in the office that has worked for an existing wheel vendor for nearly 5 years and has a lot more forum experience so the updates should be less sparse going forward. if you have questions and you can't ever reach me via phone, give Wray a call at the shop and he can assist you with whatever you need.

bump. waiting, waiting ...

Are the headers being shipped directly from Cargraphic to me or to BGB and then to me?

cooperyau

John@BGB. The Racer X exhaust and Flex Pipe have been shipped back to you this morning. Best of luck on your customer's build His car will sound insane on the track! ;-P

I was told when I ordered they would come direct to us from Cargraphic - they would not go to BGB first, to limit handling and expedite shipping to us.
