Exhaust??

Carter · Exhaust??

Hey all,

Have a 72 bus with stock 1600 dp, at the moment, and want to get an exhaust system that will give me a few more horses and a deeper, growlier sound. But nothing rediculous like stinger exhaust sound haha.

What does everyone reccomend? I've been told thunderbird headers with quiet pack is a good one. I like the look of a dual quiet pack, but I don't know if they are growly enough? Also heard A1 phatboy muffler is fairly decent so I really am in a pickle haha.

any thought apprecieted

Cheers

Quiet packs are OK but a hot dog or phat boy would give you a good growl.

Phat boys are hard to fit on bays. They generally also come with slightly bigger diameter pipe which you don't really need on a 1600. Well it's really the merged header that doesn't fit. You need a new engine mount fabricated to get it to fit. Which is a pain. Sadly the merged header is the good bit of the system that squeezes the extra hp out.

If you have the other non std header you will get a little more hp though.

Carter

hmm i've heard some after market systems can be a dogy fit, but others aren't too bad. Have you heard of / had any experience with the thunderbird brand. I'm thinking of perhaps using the thunderbird header with a phat boy muffler. what do you think?

The Matador

I like the thunderbird header i had on my Baja years ago, but i haven't been able to find one for a type 1 motor. I heard they stopped making them.

I've put a Phat boy and merged headers on my '71 with a great amount of difficulty. There is one system that works, it's a bugpack powermax or something. If you want to have a look at mine you are more than welcome.

Carter

I see. I have a feeling Mick motors here in brisbane still has them, but i am not 100% sure. Thank you for that !

cheers

I believe the A1 sidewinder is a good option. I haven't tried it and can't find a good picture

This is the most common kind of header that fits with the rear engine mount.

Carter

That looks very tidy mate. Nice. That is pretty much what I am after, but at the moment im just gathering info and ideas and that. I have also heard the sidewinder is good.

thanks for your trouble

he's a top bloke hey. haha ohhh yeah. i went in one Sat morning, and I think the rest of Brisbane had the same idea haha it was crazy!

The Matador

Heres my pipe and engine mount- note how close the header is to the motor.

I kinda like it, if you want one the same i can send you the design. Only been on the car 500km though, so really a prototype.

Sounds great.

Carter

that looks brilliant mate! Do you know what type / brand the header is. I wanna see if I can get one that will fit without having to modify anything first. But if I have to that would be great thankyou

The Matador

They are EMPI style haeders, I got mine from Classic vee dub
stainless for $450 I wanted to let the 2110 flow well so really wanted a merged header.

They have another Phat boy that looks as though it would fit without modification.
Again stainless and $450

He has a T2 stainless sidewinder also for $650

Phat bus

Hey Matador, you don't happen to know if he has something similar for type 4 engines in a bay kombi?? Hard to find a decent system for mine.

The Matador

A lot less options in T4 world. I was looking for something for my parents Syncro

That is about it from CVD- A1 though so pretty good.

Phat bus

That's an interesting system as it appears to be a stainless copy of the tunderbird sytem which is the most common one made for a kombi's with type 4 2litre mtrs.

hey guys, i have a new exhaust twin system turning up in the next few days, some advise to fitting would be nice.

Phat bus

Do you have some photo's of it?
What motor do you have ie 1600cc type 1 or 1800cc type 4 etc?
I assume it's in a late bay?

the old system is off, only took 3/4 hour. i split the 6 nuts with the hammer and chisel, 5 were pretty easy but one took bit longer as the pipe ind was in the way so i got mad and smashed it of with the hammy and all was good then. was easier than i was expecting, only because i wasnt sure how things went. Laughing

now just got to find 6 bolts and nuts, i should have, but bunnings is a walk across the road.

All done and finished.

Gabbo's Run

as you can see, bessie now has new exhaust system, no more back firing.
it was pretty easy to fit, just a bit awkward. now cathy cant hear me coming up the road, before she could hear me 2 blocks away. Laughing

Rod

so i got mad and smashed it of with the hammy

Laughing

You can do mine when you get to WA at xmas,I even let you use my hammer Wink

Gabbo's Run

Rod, when your kombi was parked next to bessie, i told Cathy i wanted to pinch your exhaust. Thank god i didnt try to do that. i would prolly be still trying. Laughing

Rod

I wouldnt even have known!

Phat bus

Does it feel any more or less powerful with the new exhaust?
It's not a 4 into 1 system, but might be some slight improvement over the standard system that is absolute crap for performance or economy.
Does it sound ok?

Gabbo's Run

Phat bus

You can fairly much trust how it feels when your in the seat over any technical specs. I'm sure you'll see some slight improvement in fuel economy too. The standard system is really a dud from all I've experienced and researched.

I've always want to know how this system performed. Thanks for the feedback Smile

"Tube Rods"? Do you mean the push rod tubes? If so you will need to back off all your tappet adjusters to take the push rods out, then the spring wire which holds all the push rod tubes in place and then the push rod tubes. This is for a type 4 motor of course. This is the good thing about the type 4 motor. You can remove the push rod tubes and change these seals with out unbolting the head.
