now i use test pipe 2.4" is good for 5AT Gear or not

Now i use the test pipe that make from stanless not have brand 2.4 "

i plan to change

which brand is the best for VQ35HR

and last question TEST PIPE or HIGH FLOWCAT is good for 5AT year 07

 

Not really sure if there are emissions in Thailand. High flow cats are good for almost the same amount of HP as test pipes, and they are legal in the US. However, if you don't care, then go test pipes as they will be the least restrictive overall. I would suggest upgrading your exhaust as well due to the rasp you will get with test pipes alone.

 

I got the cat back already

Amuse R1 titan

now i plan to change the Radiator and oil cooler

which brand is good?

I live in Thailand my friend suggest me KOYO is not suitable for hot country it will make heat engine

anyway thanks for suggest me

 

your stock radiator should honestly be just fine

I don't know if there are even radiators out for the HR engines yet either

we've used the AAM test pipes for the HR engines, and they have worked out great so far - 2.5 inch, stainless, and they fit well
