fsport intake imo exhaust just depend on how loud you want i got an M2 and love it.

Joe Z intake tube with HKS filter and Joe Z full cat back exhaust show the most HP gains. PPE headers would be the other power upgrade. That's about it.

^^ What he said. To make the most of that power, you can try finding different final drive gearsets or look into an LSD.

or k&n/takeda intake with hks and invidia mp for max loudness

PPE is currently developing and testing a true cold air intake... Will be interesting to see what kind of gains it gets.

It depends on what you mean by "best"

Do you want the most hp gain? (which is irrelevant on our cars. If you want legit hp, go buy a 350 or ISF). Then get the JoeZ intake and JoeZ exhaust.

Do you want a setup only for sound? Then get the Takeda/Greddy/K&N intake and the HKS Hi Power exhaust paired with the Invidia midpipe and PPE headers.

There are other exhausts that are quieter like the Tanabe, M2, Greddy, etc.

HKS has its own filter? don't use the one hat comes with the takeda intake?

and what if i just use invidia midpipes? would that be a good sound?

No, he meant using a drop in HKS brand filter since the JoeZ intake only replaces the intake tube.

And Ive heard sound clips on youtube with the stock exhaust + invidia and it doesnt sound that much different from stock IMO

I'm new to the Lexus family, but have a IS350C (2010) is there anyway to get more HP out of it? I have been looking around internet and can't seem to find any legit way to get more.

^Depends on what your states has as far as emissions laws. Here in SC, we have no emissions testing...just crazy property taxes. So if I wanted to increase the WHP of my 350 I'd start with PPE headers and a free-flowing exhaust.

Yes and no.

You can get an intake/exhaust/midpipe/headers but that won't really be more than ~25-30hp, most of it coming from the headers.

Other than that, you can get a supercharger kit but you will only gain ~50hp for about 4-5k.

If you want more power, you need to buy an ISF

Actually about 50-70 was what I was looking for. I cannot do this work myself, I live in Columbus, Ohio, and we do have JEGS, and another high performance speed shop here. Would anyone recommend not using someone like that to do the mods?

If you want 50-70 hp you're better off trading in for an IS-F.

You won't get anywhere near that without a supercharger, and if you can't do any of your own work you're looking 6-8 grand minimum, likely closer to 10k if you want nearer 70 than 50.

Add another $2-3000 for exhaust, and headers... and you've probably spent as much or more than getting the F, and will still have less power and an inferior transmission.

Jegs specializes in Muscle cars also. Not usually an import place.
