The only advantage the Crawford has is that in a visual inspection they look more like stock cats cause of the heat shields. The Berks definitely look like aftermarket cats.

 

Metallic cats for $100 less? Should be a no brainer....

 

Yeah, plus Berk gave #'s to back it up...I'm going with Berks..

 

yea i say berk if its between them 2 def.

 

Not sure if there were, but are there dyno sheets for 03-06 HFCs?

 

soon as i get some more cash going to get a set of berks

 

Didn't sit down with a 03-06 yet to dyno. What I'm more interested in is dynoing our metallic cats vs. Brand XYZ ceramics. That would be interesting.....

Hopefully if anyone in socal that wants to upgrade to our metal cats, we can squeeze in a dyno comparo for them as well.

 

to the OP, the car is definitely going to need a tune by now. 276whp is not bad but for all the mods you have theres definitely more to be had. In stock form they are dynoing around 265whp. Hopefully someone comes out with an EMS for the 07's soon.

 

I'm sure the aftermarket will catch up soon for the 07's. Did the Hydra ever come out for the 03-06?

 

I have Berk test pipes on my '06....definitely the best bang-for-the-buck mod.

 

how do hfc affect the x02 exhaust? I heard x02 with test pipes is WAY too loud, what do hfc do to this exhaust - anyone have them, or know?

 

There are a few people w/ the X02 exhaust and our HFC's.

There are a few more, just gotta search for them.

 

Any news on release of 07 test pipes?

Brian-

I'll be down Monday to pick up a set. Do I need to pay over the phone or online to save a set? Let me know. Thanks.

Charlie

 

Just placed the order for the test pipes. Thanks Brian! I've been waiting for these for a long time. See you this weekend or Monday. I'll be putting the car on a dynojet in a couple of weeks to see what they do with the exhaust and the Fujita intakes.

 

dyno for 03-06 ? any ?
