any know offhand of cat similiar to the cat that comes with this kit?
bought used kit w/o the cat and was thinking about welding one on the pipe...........so, with cat on there, maybe lose 10hp or so?

 

it doesnt come "with a cat". the tn kit thats the "w/ cat" just means its ganna use the stock cat. the tn kit thats "w/ out cat or no cat" means it bypasses the stock cat. and yea around 10-15hp loss/gain w/ the cats

 

....both kits replace the stock cats, theres many brands of cats that you can weld on the second downpipe. Magnaflow makes a great well priced one, or you can just call up tn and order the second down pipe with a cat although it might be more pricey that way.

 

will check out manaflow........thanks.

 

Magnaflow doesn't make a converter for our Infiniti G35s! However they do
make a universal fit converter that might work. Try Chris at Magnaflow he
knows his exhaust systems.

 

i'm not sure but i think FI uses magnaflow cats

 

im using stock cat on tn kit

 

Yup! The universal magnaflow cats are what I was referring to.... it will help you loose the smell, not too sure about the sniffer test though.

Not to be a smartass, I hope you mean you are using a STOCK TN CAT in other words a TN ST kit that comes with a cat, and not meaning a stock nissan/infiniti cat on your tn kit, since the TN ST kit regardless of model for the z or g, removes the stock nissan/infiniti catalytic converters....

Seems to me this is a common misconception about all the available ST kits for the Z and G about parts of the exhaust that they replace....

Straight out of the TN kit instructions....




Please point out where these stock cats fit into the first picture.

 

owell looked like the stock cat to me
