Just wonderng if anyone has ever seen these test results from 1996. I got this from http://www.unofficialbmw.com/e36/performance/e36_ti_exhaust_test.html.
I'm wondering if these tests were done on an M42 or M44 engine.
This might be interresting to someone planning on buying an aftermarket exhaust system for the 318ti. I noticed that some of the systems are available in the US.
The June issue of Sport Auto (German magazine) had a comparison of aftermarket cat back exhaust systems fot the E36 318 ti. They dynoed all the exhausts without any changes to the stock chip. They used the same car in all their measurements and the readings were 145.1 hp and 175.7 Nm as stock (factory claims 140 hp and 175 Nm). The results for the exhausts were the following:
Make Price Material Quality Sound Power Torque
DEM SS/AS +/0/- +/0/- hp Nm
Breyton 1201 AS/SS + 0 +1.0 +2.2
Eisenmann 1023 SS - + +1.5 +0.4
G-Power 1190 SS - + +0.6 +2.0
Hiob 774 AS/SS + 0 +0.4 +2.8
H+H 1092 SS - + -0.2 +3.3
Lorenz 760 AS/SS + - -0.8 +2.5
MK 784 AS/SS + 0 +0.7 +1.1
Supersprint 1 700 AS/SS + 0 +2.0 +3.1
Supersprint 2 782 AS/SS - + +0.3 +0.4
Schirmer 1190 AS/SS + - -1.0 +1.6
Material: SS = stainless steel
AS = aluminized steel
Supersprint 1-rohr was ranked best in the power gain area. It was the only one to improve torque over the whole rpm range. The others tended to improve torque in a narrow (peaky) rpm range. Schirmer was ranked best in build quality. H+H got the highest ranking in the sound category.
Note! G-Power, H+H, Hiob and Supersprint 2 will not fit under the factory bumper since these have 2-pipe tips. The Breyton has only 1 tip but it so big that it has the same problem.
