Nice pipes

Chris

 

nice....I want. I noticed the crawford has a heat shield, does it matter?

 

just for an update, Bryan from Berk will probably post up the dynos tomorrow or whenever he get's a chance, but the before and after dynos wtih two runs each, weather temp varied by about 1 degree, I gained about 7-8 HP and 10 pounds of torque.

 

Should not matter.

 

Dyno's are done. We need to get another car in here though for more testing. But so far the results look great.

7.715 HP to the wheels
10.055 TQ to the wheels

Averaged accross 4 runs.

 

Was this with a tune or just straight bolt on and dyno? Would you guys be able to do a group buy on this product?

 

car was not tuned. Just had the battery disconected to reset the ecu. Info here https://my350z.com/forum/showthread.php?t=305735

very good/fair price considering it's competitors are 100 dollars more.

 

Straight bolt on & dyno.

We are having a GB on this now. They are $100 off.

This car has a problem with one of the O2 sensors though. We stripped the threads on one of the O2 sensors as we removed it from the stock cat. Had to use a thread file and a pick to try and repair the threads as best we could, but may have damaged it during the whole process (lots of WD40, PB Blaster, & cussing).

 

off topic for the 2003-2006 HFC's

what is the difference between the: Metallic Substrate HFC's and High Flow Cats (HFC) other than the $100?

 

Highly recommened if you are forced induction. More durable than ceramic brick catalysts as well.

Metallic substrate on the left. Engineering sample from Magnaflow (59950 series). Ceramic substrate on the right. The metallic core sample is what it looks like before it's coated, but you get the idea.


And here's a customer posted image of the actual manufactured metallic core cat. Compared this to the ceramic cat (above right).

 

thanks for the info!

 

these look good and are a bit cheaper than other 07 HFC's. good job on coming out with a quality product at a good price.

 

whats the group buy price and whens the group buy over?

 

the group buy page is listed in the first post.

 

Are you going to make any regular straight through test pipes?

 

Yes I do have a few orders for 07 test pipes. I'll have the test pipes done by month end.

Expected MSRP will be ~$350, expected street price will be ~$250-300.

 

any check engine lights thrown?

 

Thanks for the order Brian! Can't wait to install!! -John

 

Awesome thanks! I'll wait for the test pipes to come out this month.
