Manny Forums Junkie Location: Sydney Registered: May 2002	Re: 1JZ-GTE Twin Pipe mods Mon, 14 October 2002 07:49 Just my 2 cents worth having had the twin pipes on for 3-4 months:- I got the twin dump pipes from Brendan in Maitland as recommended by the Newcastle boys in the past on this forum. He has the jig setup after making the early ones from scratch apparently. They go for $400+ from memory (GST, transport etc). You may need to custom modify the flanges to clear a Soarer bellhousing as I did for the R154 and make up your mind what you're doing with the O2 sensor as it needs to be relocated or removed. Exhaust went from a single 3 inch to 2 X 2.5 inch with high flow cat, resonators and mufflers to twin 2.5 inch all the way from the dump pipes back with twin 2.5 inch hi flow cats, resonators and mufflers. The noise level went up substantially, so a crossover pipe was later fitted which reduced it somewhat. Power-wise, I saw no substantial increase in power, 0-100 times or 400m times - 189rwkw before and 191rwkw after; not worth comparing as different temps and fuel will swing the figures either way. Under bonnet temps increased a little and I had to heat shield the trans tunnell from the outside to cool the floor/tunnel on the inside. I was expecting 10-15rwkw as had been suggested on the forum so I was obviously disappointed in the results. In hindsight, I would have rather spent the money elsewhere or saved up for some other power or safety upgrade. Perhaps my exhaust is too free-flowing now and not creating enough back pressure?
