New exhaust - ZR-1 Net Registry Forums

efnfast · 04-18-2012

Thought I would start this thread a little early. Car is at the shop for exhaust install tomorrow.
New OBX headers and exhaust from the "Racing Parts Depot" on ebay. About $840.00 shipped.
Headers went to Swain Tech for their white lightning ceramic coating. They claim 30-50% heat retention. $320.00. Took a month to get them back.
Dropped off parts yesterday at the shop. Now I've been there twice to make sure everything would be ok. I've got parts in hand, the guy says "we could have custom built the exhaust". Would have been about price comparable, less pieces-more bent pipe. Today he says "If you don't like the sound, we can cut off the muffelers and try some different ones.
Look for a quality shop before you buy some expensive system on line.
Header gaskets from Jerry. And dipstick o-ring.
Dipstick relocation bracket from Paul Workman.
Air tubes will be leaving.
You can see daylight through every piece, the fake cats, resonator, and mufflers.
System has an "H" pipe just north of the resonator.
All polished SS. Although, now the headers have a spackled white finish.
Think that's all the majors. Will post more as I know more.

Dyno'd at 311 couple weeks ago, as soon as I can swing a Marc chip I'll dyno again.
Hopefully the car will be ready tomorrow.
I'll post as soon as I have more.

I'm looking forward to see how that exhaust works out for you.

I just installed the OBX system on my Lt1.
No drone and it sounds pretty nice. Looks like the corsa from the out but nothing even close inside.
Too quiet for me, Mine was a bit short about 1-2 inches also the pipes started to darken after about 50 miles.
Got a B&B on the way. ( Many say it drones )
Enjoy the system pretty nice for the $$ !

Kb, so you're gonna trash the OBX and install B&B?

Kb7tif · 04-18-2012

Ya Way too quiet Nice though, It was boxed and shipped out today.
I restored this car here and during that I was running straight out of the cats for testing ect, Got kind of used to that type of sound- crazy enough.

Don't worry the B&B will be pretty loud. If you want to get stupid, make sure you get the x-pipe instead of the resonator.

Car not ready yet. Seems there was only about 8 bolts per side. Muff guy thinks it may have come from the factory that way. I hear a lot about loose bolts. I suspect they are on the side of the highway somewhere.
Any suggestions on what to do with the air pump stuff?
