Anyone have this set up? currently have muffler deletes. love the sound but want more power. i dont want it getting too loud where it takes away the luxury of the car. what are the whp/wtq looking like with a set up like this?

Will take recommendations of a quieter set up but good gains. im willing to do exhaust but just dont know what combo.

thanks fellas

You may want to PM zojirushi. I heard his setup in person, it sounds good. He can prob provide some more input on drone and all that.

how would you say it sounded on the outside from what youve heard? does it lose the second intake opening up sound?

and before everyone jumps on me for trying to get more power out of an exhaust system but not wanting the loud sound that goes with it, im trying to find a happy medium to suit my needs.

I can tell you from my experiences , Joez intake and Exhaust plus Sikky header best combo of all sounds and performance . Those ISF members from Socal who seen and ridden in my car can tell that. No drone at all .

I've got PPE headers only. It is a little louder than stock on cold start, sounds angry and then quiets down. The sound quality is different, sounds better, more obvious V8 sound. The power difference is noticeable. Really easy to loose grip as well as pass cars in a taller gear on the highway.

With the K and N CAI and headers, I was hitting 12.5 and 114 at infineon with lame launches. Previously, I was hitting just over 109.

Had the borla catback with headers and it was too loud for me, took off the exhaust. Your car will be louder since you have the muffler delete but probably not too loud with the secondary cats in place.

I have stock exhaust with Sikky headers installed and dyno-ed at JE. I had 40 hp gains. The sound is perfect for ME. If I had to characterize the sound difference....let me try this:

Assumption: On a scale of 0-10, with 0 = Engine Off and JoeZ or ISS with header combo equaling the loudest = 10, then the following:

0 = no sound engine off
3 = Stock Exhaust
4 = Stock Exhaust + Sikky/PPE
10 = JoeZ/ISS + Sikky/PPE

I have no idea what value to put Sikky + muffler delete.

Hope this is handy for you, in regards to perspective.

thanks fellas. that helped. of course everyone wants the most power gains but for now, i have to restrict what i want with what i need.

if i can gain 40whp and keep stock exhaust, that is good news. i do want the joez exhaust for maximum hp but honestly, the muffler deletes are almost too much already. i can weld on my stock mufflers if needed.

This is NOT a street legal setup for California, right?
How do you get around that, living there?

I can see you to pass the visual, some of us have friendly technicians around, but without pre-cats (headers), I don't think you can pass, Am I wrong? Unless you smog a stock car instead.

I live in California, removing pre-cats, cats etc.....is gonna make it hard to get the needed numbers.

I have PPE headers and a modified dual exhaust utilizing modified stock mufflers. It's all here:

^ thanks for the link lowrider

so basically, im going to leave the post cats in there.

do i still need this "o2 conditioner or simulator"

also, where is the cheapest price to get o2 sensors? i should just go ahead and buy them just incase they do strip out correct? last thing i want is the F stuck at the shop.

To put it in perspective my muffler + secondary cat delete is way louder than my friend's F, which only has PPE headers with stock intake/exhaust.
