Hi !

I'm french and i have a 350Z. (sorry for my poor english lol )

My car is stock.

I want a test pipe.

1/ test pipe with stock exhaust, there is a difference with totaly stock ? profit ?

2/ wath difference with test pipe and test pipe with resonator ?

3/ wich test pipe ?

thank you for all !!

(do you like my english ?? )

 

Also any sound clips with stock exhuast?

 

The Cats are a big power stealer. Test pipes will increase power. Test pipes make the car louder, so resonators will help lower the sound a bit. High flow cats are a good way to go also. Like the R/T cats, the flow is almost like test pipes but are a little quieter and help burn all the fuel so you don't get any odors.
