BimmerWorld Complete Track Exhaust System - E30 M50/M52/S50/S52 Swap
Nearly bolt-on center and rear section to work with M50 swap using stock manifolds
A complete manifold-back exhaust system for E30 cars running a M50 engine swap - M50, M52, S50, S52. Only very minor modification for a nearly bolt-on system!
MUST HAVE an M50 engine swap (M50, M52, S50, or S52)
MUST HAVE stock exhaust manifolds (OBD1 or OBD2)
MUST HAVE the BimmerWorld TrackCAB front control arm bushing brackets
This system from an E36 is an easy complete exhaust for E30s running a M50 swap. We have this system on a E30 S52 at the shop and were very pleased with how it turned out. The system only needs two pipes shortened, and custom hangers, to fit the E30. The cuts are made on the E36 rear muffler pipes at a convenient place with no bends. They only need a straight cut on both. The rest of the system is an easy install. The amount to cut depends on your engine swap. Our recommendation is to install the front and center, position the rear muffler in your bumper, and then determine how much to trim the muffler pipes.
This system consists of a front Y-Pipe, center resonator, and rear muffler. The Y-Pipe has been designed and engineered to time the exhaust gas pulses just like long-tube equal length headers by using a proper merge collector. The Y-Pipe leads into a center resonator that helps to tone and tame the exhaust. We prefer this resonator for street and light track use to keep the exhaust civilized. The resonator pipes connect to our BimmerWorld MagnaFlow rear muffler. The muffler is a two-section design with a clamp connection in the middle. The front pipes of the muffler need to be shortened here. The muffler is designed for the E36 chassis so muffler hanger clamps will need to be sourced.
We have this setup on a E30 S52 at our shop and it's a tight fit but works in the E30 chassis when used with our TrackCAB front control arm bushings and brackets. The TrackCABs are required because the stock bushing brackets are too large. The center resonator is lower than a full custom system but would only be a problem on extremely low cars.
This is as close to a complete, bolt-on M50 swap exhaust system as you'll find anywhere. Made by MagnaFlow in the USA for BimmerWorld.
Disclaimer: these sections were originally designed for an entirely different car (E36). They do fit the E30 chassis rather well but just like any retrofit, some modification is required. These modifications are small in comparison with the M50 swap already carried out. With that being said we are pleasantly impressed at how close these parts are right out of the box. If you have any questions on this system, please don't hesitate to give us a call or email!
