Stock NISMO and Test Pipes....

test pipe = straight pipe no res or anything
resonated test pipes = also straight thru but with a perforated resonator to help remove rasp
HFC = not straight thru

yes test pipes reonated or not will most likely throw a CEL. mine did for 400 miles. then 200 miles later went back off????? hmmmm either way the car doesnt change anything when it throws the CEL. justa heads up for the driver.

If they have long j tubes you should be ok....about to go muffler delete with the TP's in next couple of weeks. I think I found a four inch tip from magnaFlow that will work.

Yea I have to say I think U-bend whether its test pipes or hfcs, prevents any CELs. I have res. test pipes now from GTM and they have a U-bend just like my FI HFC had and haven't had any CELs yet with about 500 miles on them. Never had any with the FI HFCs either. Check out the picks of how long the bends are on my new pipes
