yeah its got twin cats...... "cats"

you can see the too small cat looking objects where the cat would go, they are actually too small race mufflers i got from the states, they straight though and basically do nothing, buttttt they look pritty catty if u ask me.

yeah Micheal when race pace told me they wanted 6k+ for a mild steel twin 3 into 4...... kinda thought to myself......... "f it, im buying a tig.

cost me bugger all.... and i got a tig now too.

now to get the thing up on jezza's dyno, give her a drink of E85 and pull the lines off the acutators :yes:

its easy man, everyone makes out its some big deal. get onto Tokentools buy yourself a welder. find a speedgas outlet so u can buy your own bottles and not pay rent.

set yourself up a good bench that the work peace will earth too. Make sure everything is always clean......... spark her up and lay beads. before you know it, you can tig : D

yea mate, the two v bands are on outlet sides of the "cats".

theres only really 4 bends in the hole thing and 2 get used in that merge from twin 3 into 4. Everything eles is lobster backed and holyshit there was alot of cuts. The whole system is no more than 5mm off the floor pan of the car, its as tight up as it can be.

So everytime i came across an area i could pick it up a few mm here and there id lobster back it so it all stayed as close as possible...... ground clearance, i like my car low. : D

all the pipe work, the 2 normal flanges, and the 4 bends i got off Jez his got contacts :D

the V bands and the 2 "cats" came from summit in the states

The mufflers AES

all up cost, around $1400 including, tig consumables. 1 bottle of Gas, and Re-flecta Gold heat tape to go on the floor pan where the exhaust runs..... just so i dont any fire issues

I got a HKS Super Dragger rear cannon which is 8" round, cut it up and opened it out to 4" using rolled SS perforated sheet wrapped with inox and packed it with GTB with one end of the SS perf tube slipped over the 4" pipe but not welded to allow for growth

Then headed over to Windsor exhaust where I got a twin 3" or 3.5" ( I can't believe I forgot wht size it is :( )with twin 5" bodied cats ( yes real working cats :) ) into single 4" mid muffler through to my backyard jobby rear muffler, all in coated mild steel cause I believe mild steel is quieter then SS as it lets the sound out the whole way instead of just out the rear end, its just what I believe doesn't mean I'm right :D

Deano, nice work, where you joined the two 3" pipes into the single 4" is that two 90deg bends welded together then a 4" hole cut in and 4" pipe welded onto it ?

What sort of coin is that gold tape worth? I have a spot where the front pipes get close to the body.... and melted my carpet :\ haha

I got some of the silver version for around $40 for 24" x 24" for where my exhaust gets a bit close to the surge tank, I have some left over if you want it and if its enough :)

Most motor bike shops have some stuff that will happily live touching the exhaust, they use it for the plastic flaring when it is to close to the exhaust

cheers mick, the merge into the 4inch is 2 30deg bends notched i basicly drew it on the ground the shape and width i wanted the two pipes to be apart. than eyed em off the pic i drew onto the pipework..... than chop chop.

than sqeezed down the 4inch so it was 3inch at the very end and welded it out.

when u look up the 4inch into the where the 3 3inch pipes are merging, you can see a straight line right though the bend doesnt really affect the flow...... one way or the other the exhaust is heading in that direction and theres plenty of room for it.

also gotta remember as the exhaust cools down it doesnt need as much area. hence 3inch into 4inch i feel is a good combo, the 3inch gives you ground clearance and also heaps of flow in the hot parts of the exhuast. Its also quieter.

Mild is quieter than stainless but also a deeper note, so it makes more drowny sounds. Stainless is also lighter than mild, less dense.

not that i care to much about the weight, but all in all its not really that heavy for what it is. ill just have to run 1 extra psi of boost to compensate. hahahaha

the gold stuff piggaz was about $110 bux from the states for a 600mm x 600mm sheet...... thats 1 full sheet in that pic
