hmm, ill be ordering tps soon, just got an 07, keep us posted on some fixes

 

bump any updates from anybody?

 

i have a question regarding high flow cats, a friend of mine said to get tp's instead of hfc's due to the nismo exhaust i have on my z tends to over time blow the substrate material in the hfc into the midpipe. is there any truth to this? i dont want the rasp that comes with tp's but i dont know enough about the the updated versions of hfc's for the vq35hr motor.

 

nismo exhaust with Test Pipes.
wayyy to raspy!

high flow cats to do have a substrate material they are either metallaic or ceramic. they are not like mufflers or resonators.

 

was that in cold start?

 

but on the new motor and new designs of the hfc's does the material get blown out of the hfc's after time like they did in the hfc's for the vq35de designs
this is the reason im hesitating on the tp's and hfc's

 

Everyone gets that hesitation, you need a tune. I got it last week pretty bad trying to jump on a highway and floored it in 3rd. That could have gotten ugly really fast.

 

ahhHA! I used steel wool, I'll give her a try again with some brillo

thanks

 

I think imma give this a try, even though my CEL doesn't bother me. Thx for the help kramykram

 

np

 

does anyone know if the AAM test pipes work???? they have that little pipe extension on it. I heard of a couple people that said it does but then again some that don't... But I haven't looked at there dash to see it the CEL is on?????

 

aam do not work. the only test pipes i have read about that are not throwing a cel are the gtm.

 

i had to stuff my aam pipes with steel wool for them not to throw a code

 

im sorry should of stated. gtm are the only ones that are not throwing a code without stuffing them. they are working perfect.

 

will the 02 sensor adapters from ebay work? or is stuffing the 02 with steel wool the best chance at not throwing a code?

has someone tried these or willing to try

 

So kramykram GTM is the only company that DOESN't throw a CEL for sure? And if so.. . Where can I purchase them?

 

i have a 06 and put aps 2.5 tps on through the ses light about 40 or 50 miles out. put on the non foulers tonight and i will let you know how they work (also stopped at advanced to clear the codes b4 i went and it didn't throw the light on the way to the shop)

 

Ive uploaded the pics to show the process. I did it today. The 30 box of brillo was like 3.95 and one pic shows me shaking the soap out as much as possible. I think the pics are pretty self explanitory and show what Kram has already explained.
