b/r all the way.

1 you will lose power with the ebay/megan manifolds.
2 you will gain power with b/r ported.

3 you tell me witch one sounds beter.


also if your going for looks get your b/r ported manifold couted and then a really nice heatsheld. that looks really nice and you get the power.

b/r cant go rong. it is a win win.

 

I allready have an ssauto chrome on my car, check my sig. I also have a ported buscher unti. I have to put in a egt probe, Just looked way easier on the buscher unit. Any more info is great, thanks

 

Oh, then you're fine

 

I have had both on my car, things I noticed were the Megan allowed me to run more boost without having to crank the boost controller to get the same boost level on the stock manifold. I implied that this meant it flowed better than stock. When I had the stocker off I gasket matched/ported it and put it back on in fear of cracking the Megan and to also gain back low end torque. I had to still crank the boost controller a few more turns to get to around 21 psi, but I gained all my lowend back and lost minimal topend from the feel of things. I would port your stocker w/ a Dremel as it is pretty easy and put it back on as it is much more durable and won't crack. You can also tap your stocker for an EGT probe.

 

I guess i should have mentioned that the only time i care how fast my car is, is at the track. I run the 280 cams so that helps alot up top, But yeah its a little flat untill high rpm, would be sweet to gain a bit of that back. also the stocker i have is allready ported via buscher. I have had my megan on for 5 months with no crack yet, but ill need to mount an egt gauge also.

 

Port match the stock manifold yourself.

Dc sport manifold version 2!

 

To be honest, the money it cost for the manifold is not worth it unless you have a bigger aftermarket turbo....I'd rather spend the money on something else.

 

Jun and Tomei recently released a manifold for stock turbo. Not sure how good they perform though.

 

How does the Megan manifold perform with a turbo upgrade (that will match up to it)?

 

Billet Design said they did a dyno test before & after and gianed 22 HP on a stock turbo. They also said they've installed over 20 Megan headers over the past year w/ no cracking issues.

 

Yup, that's where I got mine installed over a year ago...no cracking issues.

 

What about installing their manifold and their O2 Housing? I heard you may get some cracking if you were to install both of those items because of there being no support for the rest of the exhaust system. I read on here at one point in time that you should either do one or the other...
