Hey guys,

I cant really decide on dump pipes. At the moment im throwing up between xforce, hks and tomei expremes.They range in price a fair bit,

My question is, is it worth spending the extra money to get the tomei's. Is it just build quality or do you think there would be any gains between to two.

Thanks guys,

Spend a bomb and get CES race dumps and front pipe. Boost response improved somewhat. If you haven't already you also get good boost response gains port-matching the manifold to turbo ports (on the manifold only with non stock turbos) like in pic.

Have you used these Doo Doo. I rang up up about them, they sound great but pricey. From the impression I got regular aftermarket dumps could increase boost response on upgraded twins by about 300-500rpm, but these race pipes could increase boost response by 800rpm or more.

Anyone have any experience with these?

These are on the car at the mo, put them on with the stock turbos, pretty good result (awesome sound too). I have custom turbos that have the kick of 2540's but have boost (up to 12psi) from 3000rpm with full boost all in by 4000rpm.

Thanks Doo Doo.

They sound like the have a good result. I will defineately consider them. I will be using something with 2860-5's and from the sounds of it the race pipes and cam gears should dial out a lot of lag and increase response.

^^ Doo Doo,can you tell me more about the turbo's you are using?

They're a custom job not available off the shelf- my tuner had them made for his RB26dett powered Z- not sure who by, he won't tell me. They have the response of 2530's and lose 4hp on 2540's. His Z has about 540hp at the wheels with the boost response already posted (plus cams and gears, I think he's running about 20-22 psi) . When he got them in for me they were 1500 each brand new. Am switching to Motec (power FC does get a little reversion with this setup)

Thanks Doo Doo.

Forgot to mention i have tomeii cams and gears dialled in for better response.

hey doo doo who made you piping

I did

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
