Building the ULTIMATE 2018 Subaru WRX STI - Part 5 (Catback Exhaust System & New Business Revealed!)

It was already made. Its the Tomei

Wish it was a Tomei collab 😤

no tune for the BOV?

I think you guys forgot the gasket for the BOV......

Tire size? 🤔

I love the way you guys work with cars . I'm a hug suburu fan and this car is off the hook .
I'd really love to see you guys do a skyline r34 vtec spec next .
Would be a lovely build for you guys

she needs aftermarket down pipes !!!

I sont loke the way the exhaust is sideways but this project is something good

What kind of greddy exhaust is this? Did greddy use an exhaust model that they already produce or is it fully custom?

The before and after sound of the exhaust is ridiculous I wish they made that exact exhaust for the 2014 wrx.

Very very very nice

This car is my favourite

Colab Exhaust sounds 🔥🔥🔥🔥 congrats on the partnership guys , awesome 🙏👍. Always such sick content keep up the awesome builds 😎

Hey I have the same bov

why don't throtl make a competition and who wins throtl take his car and tune it....imagine how many people would like to have their car tuned by throtl :D … thank me later

Time for evo 10

Dang Greddy!! Big congrats 🙌.

Wow that before and after was a big difference 🥵

Always good . See you next project. Indonesia

Possibly should learn about recirc valves and how they work on maf cars. Bad idea to run bov without speed density

I didn't watch it per upload im gonna watch it in one click😉 dang love this build

What a beauty!

👌👍

it will also fit 2011-2014 wrx and sti sedan

Greddy or Invidia R400... tough choices now

2.5 down pipe to 3" catback?

Why greddy bov doesnt have stututu sound?

please make more of those exhaust

Was that with stock down pipe

Good sound 👍🤩

Please bring this back 🥺

Do you have to tune your car when you install and BOV?

Nice :-)

Curious why you guys keep double handling so many jobs? Eg putting a new tmi on then pulling it of to fit a bov. Wouldn’t it been easier to do it in one hit. Just my thoughts. But its a beautiful build boys. Really enjoying watching it.

Why a blow off ? Recirculating is better.

I don’t think it’s good to run a vent to atmosphere blow off valve with the MAF still on everything I’ve heard is that you need to go speed density to run it

Just too loud

Will this fit for 2021 STI?

Is this just the regular Greddy RS cat back but with a 170mm Greddy burnt muffler tip attached?

How many MM is the exhaust tip?

i dont love this exhausts its looks like stovepipe

just realized this is the shop TJ Hunt uses lol

proper fucking suby sound of the 90s. love it

I need this!!!

Greddy and Throttle. How many left? I just joined the VA STI club. Take my money and swap me some drip drip please!

Left side exit is needed on these cars in my opinion

i have number 5

What car should we make an exhaust system for next? Comment Below!
