newbie here ..... help please :D
 

Hello fellow 86/brz owners,

i just got a 86, AT.... yes i know, should have gotten a MT but i am past that at/mt discussion.

So here is what i want help/advice with. Before reading this .... please know that this is my first tuner.

1. I was hoping some one could break down the whole exhaust system and how it works. As in i am new to the terms and process. (yes i am that noob)

2. I want to start with changing the header and if i get a new header, what additional mods am i looking at for optimum use of the header.

A fare warning to who ever will reply, i will have a lot of questions to better understand things.

Appreciate the help!

Thanks

This pic should help. A header will require ecu tuning.

Hi there boxhead. I'm a newbie to this forum but not a newbie to cars. The exhaust system is broken down into 3 main sections, the header, catalytic converter, and the muffler. There are more than 3 pipes but these are the most commonly referred to parts to upgrade. The header funnels all the air together into one pipe which then gets filtered first by the catalytic converter to reduce emissions, then it goes trough the muffler to get the proper back-pressure for the exhaust system to work properly.

If you are upgrading the header, I'd recommend also upgrading the exhaust from after the catalytic converter (cat-back exhaust). Then go to a shop and get your cpu tuned.

For a more visual reference: [ame="https://www.youtube.com/watch?v=iM_QmVF2-fQ&list=PLHxU7q4gi5_sFJCSzL7x5zPsz4WxzuKgd&index=3 "]Searching for Torque - Header & Exhaust - FR-S Long Term #4 - Everyday Driver - YouTube[/ame]

Not always, some car with headers do not trigger the check engine light. But if your looking for a performance upgrade and not only just for sound you should get the ecu tuned.

Is it just me on this forum who waited a whole year until I wanted a new exhaust?:iono:
Guys on here get new aftermarket exhausts couple weeks after getting their car!

I've had my car for 4.5 years, on the forum since before that, picked up an OFT about 6 weeks ago and a header is awaiting install after I finish some bodywork (fender bender). 4.5 years of a stock powertrain (minus K&N filter installed at 30k miles).

If you're able to put your foot to the floor on corner exit you took the corner too slow. I don't care if you've got an AT and racing slicks, plenty of power in this car.

:burnrubber:

Agreed however oft + intake for me and then a few small aesthetic things then once I am happy in that department I sh go bonkers LOL

Save your money on the intake; there's no real value in it. The OEM intake is very well designed, so all you need is an aftermarket filter. If you really really want an intake, get GrimmSpeed's. It's the only one that maintains a reasonable AFR. The others "make power" by leaning out the AFR, which isn't good.

That's very true.....actually our car has a very strong 2nd and 3rd gear pull after a corner...sometimes I thought I am driving a Porsche lol...

Yeah I was leaning towards a replacement reusable filter to be honest I was never a fan of bolting on a CAI to a NA boxer there has been some extensive discussions about it on wsc and they all lead to some crappy results but thanks for the suggestion

I definitely want to go oft though that probably will be my first "mod" followed by a better head unit I have the base model and boy it's archaic to look at in such a nice car

I think those who buy aftermarket goodies right away probably don't owe as much debt on the car if at all.

I'm still on stock exhaust and only now looking into getting a Perrin 2.5 resonated cat back, I've had the car since 2013. It's slow going and I still have almost 2 years of payments left on the car. But the exhaust just can't wait.

Yeah paying it back has a huge part to play but for me warranty is pretty awesome haven't had too many cars that have come with warranty so I want to enjoy the bliss of getting paid to fix my own car under warranty but once that's over it's go time LOL

Oh yeah enjoy that while it lasts, I'm at 65k so I'm well outside the warranty so now is the time for exhaust. Once I pay this sucker off, then I start on the list of mods for the track.
