Description

RB30-25det HEAD ONLY T3 - T4 - V-band - Single Scroll - Non AbsAfter years of development of our merge collector from extensive dyno time and feedback from the top tuners in the country, we have found the perfect balance of boost control and flow. With minimal back pressure where the manifold meets the turbo, you can be sure that you're getting the best flow possible from your turbo manifold. FLOW = POWER. NOTE: The RB30 needs bigger wastegates because of the higher gas speed, we recommend using a 60mm wastegate,

After years of development of our merge collector from extensive dyno time and feedback from the top tuners in the country, we have found the perfect balance of boost control and flow. With minimal back pressure where the manifold meets the turbo, you can be sure that you're getting the best flow possible from your turbo manifold. FLOW = POWER. 

 

NOTE: The RB30 needs bigger wastegates because of the higher gas speed, we recommend using a 60mm wastegate, depending on the rear housing a size you can get away with a 50mm


NOTE: The only difference between the RB25 and the RB25/30 manifold is the height, Our manifolds for the RB25/30 are 24mm lower than the RB25 version so these will hit the engine mount if you fit to a RB25.

 

  • WILL NOT FIT WITH ABS - We do have a abs manifold under our other listings
  • Fitment = R32-R33-R34-Laurel-Cefiro-Stagea-S Chassis
  • 12mm CNC machined flanges
  • Features a 6 into 1 merge collector


5 year no crack warranty

10 year no crack warranty if fitted by us in store


Manifold Manufacture Times

Our manifolds are made to order, manufacturing times vary depending on the time of year & our current work load.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
