Diy Exhaust Upgrade

[Twinky]

Have a welder? Want a bigger exhaust? In fact you don't even need a welder (although it will end up cheaper if you do :dance:.

Go down to your local wreckers such as the wonderfull U-Gank it here in adelaide and go down to the falcodore section of the yard.

There you will find two sizes of exhaust, 2.25" and 2". I opted for the 2" because it should suite a 4k just fine. The 2" systems generally come from

the early model cars and the 2.25" come from the newer models. The other reason I chose the 2" was because they come with longer stright sections and the

hump for clearing the axle is a bit longer. They also had less resonators/mufflers taking up precious exhaust length.

So after about 30 mins of walking I came accross these already pulled.

So how mutch did I pay?? $24 for the lot.... awesome....

A bit of hacksawing saw the mufflers off (do this before purchasing, otherwise you will get slugged for the mufflers) and hey presto you have plenty of bends and straights to make up an exhaust.

Over the weekend I'll be putting this together and taking pictures along the whole way for all to see.

Or dumpster dive an exhaust place late at night and get them for free. Not that I know of any RC members who do that :dance:

Truck exhaust is also good to use. 3" makes great droopy tips :fuzz: Please tell my you will be using more than an oxy set and a couple of coat hangers to weld it up.........(thats what we did :dance: )

[Twinky]

Will be using mig to weld up everything.

Awesome idea, I was thinking about doing something similar to my old festiva :dance:

I have used it for body repairs....lets just say it was tricky.

 

For exhausts, it is perfect. Have done a heap of exhaust mods.

Well got some work done this weekend. Measuring, cutting angles and welding up the pipe.

A little trick I use to connect the joins a bit easier is to cut short fins in the pipe and then hammer them so that the overall diamiter of the pipe goes down a few mm, creating a bit of a lip that

allows you to weld a bit easier. It takes a little while of measuring, cutting, checking, re measuring, tacking, checking and then finally welding it to get it right. My welding is not the best but there are no holes,

any little pinholes that might be there will be covered with goop just to make sure.

 

Old middle muffler vs middle muffler from a falcon

 

Maybe a little close to the diff but should be fine

 

 

 

Still the middle muffler to cut and weld, then the secondaries to measure cut and weld.

Anyone in SA have aftermarket extractors??

I cheated when I did the exhaust on my KE20. Went under the diff - mush easier ;)

was there enough ground clearance??

Thats a really good idea mate, under diff exhausts are sort of frowned upon by australia's police force if they don't clear 88mm or whatever your states clearance laws are, i'm pretty sure it's only 88mm for QLD

lol bet that flows good

100mm

[SLW42]

Meh 100mm my bad sorry to mis-inform you guys, last i heard it was 88mm sorry

[Old fella]

G`day mate, nice to see someone using their brain. It should work just fine.

When I built my system I discovered that old trampoline frames are the friend of the exhaust builder. They`ve got good circumfrence and lots of nice bends.

Good luck with the build.

Under the diff was for a competition car only, so no issues with ground clearance. Biggest bend in that system was where it left the extractors and bent around the firewall. Oh, and the droopy tip.
