First post, been lurking in the background for quite a while now.

I haven't found anyone on here who has had this done yet so thought I would share it with you. Sorry in advance if it's been discussed before.

Had all my exhaust parts ceramic coated before installing. Should really help with underhood temps and flow much better.

The coating I went with is good up to 2000 degrees. All except the test pipe are coated inside and out.

Couldn't tell you why I picked black as my color.

Rv6 precat delete, Billy Boat/XLR8 j-pipe, Rv6 resonated 3rd cat delete are the brands I chose.

 

Nice how much?

 

$140 for all of it.

He had some less expensive coating there but I went with the better stuff.

The j-pipe was the expensive part as the charge is by the foot.

The guy said he would give a big discount for larger quanities.

 

Hmmm...Looks nice, but I wonder how much this is going to help performance?

 

To be technical this is how it should work

It should accelerate the pulsed-vacuum effect of the precat deletes, resulting in more effective scavenging of cylinders. The increased velocity of exhaust gases produced by higher exit inertia not only clears each cylinder more quickly; it should also draw in the next fuel/air charge more efficiently.

Simply it speeds up the exhaust flow. The thermal barrier of the coating keeps the heat inside the pipe which speeds flow.

It should decrease the precat delete temperatures by at least 300 degrees.

 

pretty cool...

 

hmmmm... any plans to get this on a dyno after install? I'm curious to see how they stack up against ones that are nOT powder coated. It looks tight though. It would definitely pass visual inspection for those emissions guys. Nice!

 

looks clean. I thought jet coating cost more than that.

 

Kudos for you... I wanted to wrap my precat deletes, then found out it would deform the ss after a while

Then I wanted to ceramic coat and got a quote of $100 just for the precats (that idea went out the window)

Looking at how good yours look... Wow dude

And not only will this help exhaust speeds, but your engine bay will be completely cooler

What shop did the work for you...?
Maybe I can mail them a few components for them to coat for my turbo project

 

probably won't do much other than heat dampening, pretty cool though

 

looks great

 

looks nice and functional too

btw... your precat deletes don't have flex pipe? is that a new version?

 

basically its like a vacuum that sucks the exhaust gasses out rather than having them forced out by the cylinder heads?

 

great observation... since I've been installing these bad boys left and right, when richie made the order for the second batch I told him to eliminate it he listened...

 

Looks Great!!

 

I installed them today. Took me 2.5 hours for everything. No hiss , no leaks, very happy with the sound. I have stock catback. Permatex Ultra Copper is sealer I used on all flanges with the gaskets. It's the best high temp stuff I've found.

Performance is way better than I expected. Sorry no plans to dyno it. I have a racecar I do that kind of stuff to, this is just my street play toy.

The underhood temperature is quite amazing how much less it is. Well worth the cost to me for that reason alone.

Here is where I had it coated at. Very nice guy and very very reasonable prices.

I was under the impression that the straight shot the exhaust gasses have leaving the manifold now will already greatly reduce underhood temps vice all that heat collecting in the cats?

I'm jealous but mine are going in Monday rain or shine.

 

you in STL dude ??? Hit me up for a photoshoot or some like that.....

btw a video with drive by, drive away and inside drone would be very helpful.....

 

I'll try to get a video with sound this week.

I live about an hour south of STL but my girlfriend lives in Wildwood and I am up there all the time.

I don't have enough posts to PM you yet

 

i was wondering about the flex pipe on the rear precat delete too. stock cats don't have them so i thought the rear flex pipe wasn't necessary either. makes me wanna try them without the flex pipe and see if they hiss too.

plus if they were resonated like the 3rd cat, i think that diesel sound during cold start up will be reduced too

 

no they still hiss... I am going by the thread local dude posted up regarding the very thing...

https://acurazine.com/forums/3g-tl-performance-parts-modifications-112/r-v6-pre-cat-delete-hissing-noise-709101/


i've been reading through plenty of forums.. all these straight pipe headers seem to all hiss... no exhaust leaks...

I got used to it when I had mine

 

I get the diesel sound on cold startup, it goes away after 1 minute. Its the ecu intentionally warming up the cat. ULEV system...

 

^ correct and it doesn't take long for the ecu to think the cats are warmed up

it is this feature on our car that caused procats to fail

 

LOL its ight man....PM me or email me at sadhwani.anil@gmail.com

 

i just have a quick question for you (am not a tech junkie so don't burn me yet):

so if precats, jpipe and test pipe are coated they create a vacuum effect and hence they increase the speed of hot air thrown out and fresh air fed in, hence keeping the shit cooler and hence increasing performance

using this technical description, how would it work if you have jpipe, test pipe as well as full exhaust ceramic coated (no precat deletes at all, so everything before jpipe is stock and everything after jpipe including jpipe are ceramic coated) ???

 

The cermaic coating decreases in affect the further away it gets from the engine.

The most important is the precat deletes or you could also coat the stock converters.
