01Overview
Schmiedmann's S-Tech sport manifold for the N52 and N53 six-cylinder in the E90.
From the factory these cars carry the catalysts built into the manifold itself — a heavy, restrictive casting sitting right at the head. This replaces it with a 100% stainless tubular manifold and frees that section up.
At 6 kg it is the lightest manifold in the Schmiedmann range for this platform.

02Two ways to run it
Because the standard catalysts live inside the manifold you're removing, where they go next is your choice.
Tell us which way you're going and we'll put the right combination together for you.
The road setup
Schmiedmann's own recommendation for a road car is to run this manifold together with a sport catalyst system — a separate section that carries the catalysts lower down, under the car instead of up at the head. Nothing is added to the manifold itself. According to Schmiedmann, a car set up this way keeps the dash clear and stays ready for its inspection.
The build setup
Manifold on its own, straight into whatever system the car is running. The route taken on track cars and dedicated builds, where the standard exhaust behind it is coming off anyway.

04Fitment
Built for the BMW E90 with the N52 / N53 six-cylinder:
For left-hand-drive cars.
Send us your VIN or a photo of the engine bay and we'll confirm it with you before you order.
For left-hand-drive cars.
Driving an xi?
Schmiedmann list the 325xi and 330xi under this part as well. Four-wheel-drive cars run extra hardware alongside the exhaust, so before you order an xi we'll confirm it with Schmiedmann for your exact car — send us your VIN and we'll come back to you.
Running a swap?
It follows the engine, not the shell. The manifold bolts to the cylinder head, so an N52 or N53 in another shell takes the same part.Send us your VIN or a photo of the engine bay and we'll confirm it with you before you order.
05Fitting Notes
Guide time4–5 hours
Hand these to whoever fits it — they save time on the car.
01The standard manifold comes off with the catalysts inside it. Plan where the new catalysts are going before the old one is out.
02Going the road route? Have the sport catalyst system on the bench at the same time — it all goes in as one job rather than two.
03Schmiedmann recommend the fitting is done by a workshop set up for exhaust work.
