Which headers should I buy, bang for the buck?

[MuRCieLaGo]

Hi

There's a lot of headers available for our ZR-1. Which ones are the best bang for the buck? I replaced the stock resonator with a Magnaflow and now it's as quiet as an electric car. I live in a small town, if the police hears my car now, everything I will put later on will be too loud for them.

I know the OBX and other eBay brands are much cheaper than Stainless Works. Got a OBX exhaust manifold on my RX-7 and I've never had a single problem with it for 6 years now.

Waiting for your reviews,

Thanks!

I'm running OBX headers and exhaust....I paid 525 for the headers and I believe 510 for the exhaust......I like them, car picked up some good power and is not too loud.......Has a nice throaty sound and does not sound tinny ......Don't believe the police should hassle you over these....

And what about the fitment?

I'm also running OBX headers and exhaust. I believe the fitment has the same issues as any others. Rubbing the steering shaft, O2 relocate, dipstick issues.

I have been running OBX headers and cat back exhaust. Header fitment issue is not given - some cars do, some don't.
Me and Jim V., a few years ago, measured exhaust pressure off of O2 sensor bung hooked up to a pressure gauge. Second gear, 6,000 rpm between OEM exhaust, OBX vs. Corsa was 1.4, 1.0 and 1.0. First two measurements were with my Z (OBX headers) and the last measurement was with Stainless Works headers.

I'm very happy with my OBX headers. I did have interference with the steering shaft, but a combination of dimpling and slipping a shim under the engine mount were fairly easy. My guess is, anyone willing to take on the job of installing headers probably has the wherewithal to address interference issues.

I will note that this is the first header I've bought that didn't have a collector (with bolt holes) attached, but I guess that's not a big deal. Clamps seem to do the job. Perhaps this is done for ground clearance.

Jeals made by Corey, no fitment issues at all.

I hear Coreys Jeals are the best if you can get them.

I don't know this for sure (feel free to correct me), the OBX headers are around $500, and most (all?) others are $800+?

Price was a factor for me.

OBX $584, Stainless Works $1,449. And exchange rate with Canadian Dollar is pretty bad for me at the moment.

Would I have to relocate some stuff with Stainless Works headers?

Never heard of Corey Jeal headers.
