Re: downpipe for t3 t4 turbo
It depends on the manifold. The manifold and downpipe have to be a matched pair if you're buying them commercially.

Re: downpipe for t3 t4 turbo
if you can weld, i'd say buy some flanges and mandrel bends on Summit and have at it!!...otherwise, i think you might be out of luck if Dezod doesn't have it....

Re: downpipe for t3 t4 turbo
like Boiler said its going to be down pipe manifold combo other wise it will be a one off down pipe. Im unaware of anyone other than Dezod that make a DP that fits their manifold. As a "off the shelf" type part that can be ordered
Re: downpipe for t3 t4 turbo
alright i guess i will just have to weld one any suggestions should i keep my stock cat or get a different one or should i ask will it improve alot with a different cat with a turbo
Re: downpipe for t3 t4 turbo
Dezod makes the best manifold, downpipe, & 2.5inch tube back. All can be had for around 800 if I'm not mistaken. Good fitment space is tight. I am having issues with the downpipe planting itself on my frame & rubbing severly. All brand new motor mounts, subframe aligned twice, new transmission, new clutch, new flywheel, new axles, 3 turbo assembly tear downs to adjust fitment......and downpipe still won't budge....I believe I am the only one to have any issues. Everyone else I am aware of has had very good luck with it.
One note I must add is the 2nd 02 sensor bung on the DP is absolutely useless. You can't put a sensor in there with it on the car and if you try installing the turbo assembly/dp with a sensor installed it is literally smashed against the block. I'm sure 5,000 of vibration would break the sensor. I had a bung welded on the supplied tube for my AFR gauge.
