Is it necessary to install a AEM catback if I want to upgrade to bhr midpipe? Or headers? Or should I leave them untouched? What are the benefits to upgrade headers and catback together with bhr midpipe?

 

No but most people do because you are already under the car. You know, 2 birds 1 stone type deal.

 

AEM doesn't make a catback anyway

 

Better flowing exhaust.

 

1. there is no AEM catback

If you are installing a BHR midpipe, you can use any catback you want (even stock) but if you have the $$, I'd recommend upgrading for looks / sound.

If you get the BHR header (whenever that comes out), you will not be able to use an aftermarket midpipe as it will not fit. the BHR header should come with a compatible midpipe so keep that mind before buying something now.

 

Ok thanks

 

But will I be able to shoot flames if I install the bhr with resonator and keep rest of the catback original on(includes muffler)?

 

Yes

 

nice!

 

you're doing this just to shoot flames?

 

Kids. When will they learn?

 

if I will be able to pass etest, catless is better for car's health, and yes I love flames, :D I seen people cooking up turkey by using backfire

 

You won't pass emissions testing without a cat. Not even if you bribe the inspector with a scorched and carbonized turkey leg.
