Hi Guys,

I just installed K&N intake, borla headers and borla cat-back for my g35...
but i didnt like the sound it looks its quite, i want it higher... should i remove the cats(catalytic converters) since i have a porblem with it..so what u advice me to do ?

+ what more mods should i install ? pulley? spacer ?

One more thing do u know any good G35 tuner around idaho area ?

 

Add test pipes if you don't get emission tested, get an online tune from seymore4 of the forums, and with your mods get a half inch p spacer.

 

so u mean i have to remove the cats and put test pipes instead ? + can u tell me the best test pipe to use ? remember i want to increase my exhaust sound

 

The perfect sound and HP comes from motordyne resonated test pipes.

Test pipes, watch some youtube vids

 

Those are the ones. Check the marketplace here someone is selling for 400$ with "50" miles on them.

These are RESONATED test pipes. If you hate rasp you need these.

 

so whats the best test pipe ?

 

That question has already been answered, the Motordyne ART pipes.
