Thanks Mainstream for my custom exhaust today. This is the 2nd time they did custom exhaust for my cars, and it is perfect again!!

It is really hard to make I4 engine sounds good, especially the 1.8 Toyota engine in the lotus, because there is really not much room for pipe and muffler. The Stock exhaust sounds like crap (it drones and sounds kinda.. hallow, no personality at all), and I was looking for some clean and a little louder exhaust sound compare to stock. Everything on the market is either too expensive, too loud, or too heavy. Some lotus exhaust uses bike muffler and can't even pass most of the track sound regulation.

Mainstream did this exhaust for me and it fits everything I want with a very reasonable price. es its not shinny, and its not name brand, but its light (around 15lbs), functional and sounds damn good. Very close to how OEM exhaust sound, maybe 20% louder. It drone less than OEM exhaust at low RPM and sounds more aggressive than OEM at high RPM. I didn't get tip at all, you can barely see the exhaust pipe unless you go under the car. I love the stealth look and I think the rear end looks a lot cleaner now.


Humm, what exhaust




Where is the exhaust?





Here it is!!




This is pretty much what it looks like compare to stock exhaust, just without the tip
