Hey /o/ . . . so I got a G35 Sedan and everyone is telling me to put on a custom exhaust and a cold air intake. Is that just stupid though? I don't plan to boost the engine... it's just a DD. Will CAI+Exhaust as only mods actually increase performance, or will it just be noisy?

small gains, might be a little zippier and accelerate a little better. To really see any increase from them you would need a tune.

>Will CAI+Exhaust as only mods actually increase performance
Unless you do a full exhaust, the difference will probably be negligible.
>it's just a DD
Keep in mind a lot of exhausts will drone to some degree at highway speeds, and those K&N filters require regular cleaning and re-oiling.
They both make cool sounds though.

Thanks. I think I will be boring and just leave it stock. I am pleased with it as-is anyhow!

now you delete the thread before we start talking corvettes.

Intakes sound amazing on the vq35 and are not any noticeable until going WOT
>>16713584
Depends on your definition of "small" gains.
Good catback + precat deletes + jpipe/headers + intake (including manifold and CAI) yields around 60whp in gains. I'd say that's pretty good. Pretty much the equivalent of a low boost supercharger.

It's not cold air if it is getting air from the engine compartment.
>>16713584
Keep it stock.
someone give me a quick rundown on the different types of exhaust
>precat, glasspack, straight pipe, h-pipe
I'm pretty sure cat delete is just cut out the fucking catalytic converter but still
???

this old shit. repeated since obd1 days. the stock ecu can vary the fuel and timing map +-20% or more.
>>16716206
didn't give my 22r 60 hp kek.
>>16718119
precat iis emis equip
glasspack is a straight through resonator. shaped like a sausage. You know the ones
straight pipe is no muffler
h-pipe ia a balance tube between the 2 banks of a true dual exhaust

That not what he asked, asshole.
