Nah, i dont think thats them. Im pretty sure theyre in Bathurst. Same name though; maybe it is them, but they just have their factory in Bathurst. My exhaust guy is away, so i camt find out atm.

Its a bit hard to tell over the net what sort of sounds it makes. Do you have a sort vid of it on youtube by any chance?

[Shaun]

No i dont. Im hopeless with computers too, so i doubt i could figure it out. Maybe i could take a vid of it with my digital camera, and upload it somewhere. Im just hopeless with converting files etc; i dont understand that at all.

I gave them a ring and there factory is in bathurst, s i think they are the same place. If you can check some time it would be greatly appreciated as im going to do the same setup as your car.

[Shaun]

Ok, ill check for you as soon as i can.

If you want to check the exhaust out, im sure we could arrange something (if your in or around Sydney that is). Im in Gosford.

Ill still check for you, but im sure the Hi Tech in Sydney and Bathurst would be the same company.

Oh no rush man i dont plan on doing it tomorrow or anything, also im in adelaide but thanks for the offer

[Shaun]

No worries. Ive got the diff out of the car at the moment, so the exhaust is on the bench. If you need exact measurements of the centre muffler let me know. Ill be putting it back in on thursday.

Actually exact measurements of the center muffler would be awesome, saves me from guessing under the car. Cheers

[Shaun]

No worries. Ill send you exact measurements, and a photo of the centre muffler when installed in the car. Ill do it in the next few days.

My engine makes 440rwkw and the exhaust meets Qld noise requirements. It is 3.5 inch from turbo all the way back, includes CAt and 2 x 3.5 inch mufflers.

Ok, Ill have them to you by the end of the week.

Im pretty sure i mentioned that the wastegate was venting to atmosphere when i had the car tuned. I dont think it would make any difference if it was plumbed back in though. Ive since made another front pipe that plumbs the screemer in, and ill put that on this week.

Sirracer and GTR1993, ill just post the info here rather than send seperate PM's.

The dimensions of the Hi Tech made centre muffler are: 305mm long x 220mm wide x 150mm thick. As you can see from the photos, the design is centre in and offset out with perforated tube through the middle. The offset is towards the passenger side of the car.

The specs and product code of the rear magnaflow muffler are in my first post.

I dont think there is any more you should need to know to order the same custom muffler from hightech, but dont hesitate to ask if there is.

These are old photos, so i can take some new ones tomorrow when my exhaust is on if you like.

Shaun.

*****EDIT***** Make that offset in/ centre out in design, with the offset towards the drivers side of the car. Sorry; i had it around the wrong way!

Ill take some more photos tomorrow so you can see if there is more room around the mufflers if you want to go bigger. With the way the US dollar is at the moment, maybe Magnaflow wouldnt be the most cost effective option. I think mine was about $330 (exact price is in first post), but that was when the dollar was about 0.94. It might be worth getting two custom mufflers made from Hightech. There is heaps of room around the rear muffler.

I actually bought 2 magnaflow mufflers the other day (the center muffler im using center in center out) and they were $310 each! Im going to try this if its no good ill get the custom one, but i had the car int he air and should fit fine.

Thats a good price for the two mufflers. Were they the same as my rear one?

Im no expert, but i think you might find that its a bit loud, as the centre offset muffler gives really good noise supression. Ive run my car without the rear muffler (with only the centre custom job in), and it wasnt that much louder than with the complete exhaust on, which i found suprising. If youve still got twin turbos it may not be too bad though.

Anyway, you'll be able to sell the muffler for a good price if you find that you dont need it.

Yea i thought about that, ill try this way and if its no good i can always change it to the same muffler that you are using, but they were cheap so i thought why not.

custom FTW

people think i have a stock exhaust until its under load

also you seem to of gotten a bloody good price!
