IntroductionI have wanted to upgrade the exhaust on my Mk1 MR2 for a long time, as it such an easy modification to do. But, the previous owner of my car had paid for a new Toyota exhaust to be fitted to my car only a few months before I bought it, so junking that would have been a waste. Therefore I waited until it had corroded away (which they always seem to do after 3 or 4 years) and then decided to have a stainless steel exhaust fitted in its place. Most stainless steel exhausts are only marginally more expensive than the mild steel Toyota exhaust, but come with a lifetime guarantee, unlike the Toyota exhaust which is pretty much guaranteed to be useless after 3 or 4 years, judging by what I have read! Noise and PowerMagnex don't quote a specific power gain for their Mk1 MR2 exhaust, but their general literature implies that you can expect a minor increase in power. My car is certainly slightly more responsive with the Magnex exhaust and JR air filter than it was with the standard Toyota items. The Magnex is not an overtly loud exhaust, but it adds a deep throaty note, especially with the throttle open and the revs building. Which is just what I wanted: an exhaust that sounds good when I push the car hard, but does not deafen me when I am cruising on the motorway. Oh, and if you are pushing hard, sometimes it will pop and crackle on the over-run, lovely :) The Magnex has longer tailpipes with a wider (2.5 inch) diameter than the original exhaust, so it looks good without being over the top. Build quality appears to be superb. FittingI let a local Magnex dealer (Elite down in Rainham, Essex) fit my exhaust, which helps with the guarantee because they stamp the guarantee card after checking the engine and exhaust mounts etc. If you want to fit one yourself the process should be very simple, although you may need somebody to help you lower the old exhaust and offer up the new one because they are rather heavy. They can be bought mail order from a number of places, including Fensport. AlternativesMongoose sell a Mk1 MR2 exhaust which appears to be very similar in terms of noise, power and looks to the Magnex. Janspeed have offered both mild steel and stainless steel Mk1 MR2 exhausts for a long time. I heard recently that they had ceased trading, but apparently they are up and running again now. Interestingly, their Mk1 MR2 exhausts are very loud, but they do specify a performance gain of approximately 10BHP. From what I have read, the mild steel exhausts corrode very quickly, so it may be wise to opt for their stainless steel system. Certainly if you are looking for a power increase, and do not mind the noise, this is one to consider seriously!
The other company I considered was Powerflow. They have a number of dealers around the
country who will custom build an exhaust system for you using Powerflow pipes etc. From what
I have read on I have written a comparison table of Mk1 MR2 exhausts for the IMOC-UK. |
