I ATTACH PRODUCT PHOTOS AS WELL AS PHOTOS OF MY VEHICLE BEFORE AND AFTER.
I bought this exhaust for aesthetic reasons and installed it myself on my 2004 Toyota Corolla E12 Hatchback. First of all, I have to say that it is a high-quality product, with a very nice and sturdy design that fits perfectly on my tailpipe with a diameter of 4.8 centimeters. It is the best value for money product in my opinion, as long as you find the right dimensions, because before this, I had bought another one that didn't fit, and luckily they accepted it back and exchanged it for this one. If you expect a change in the sound of the exhaust, then you are looking at the wrong product. It doesn't affect your genuine Exhaust in any way, only on an aesthetic level. I would also like to point out that during installation, it has 3 screws (which makes it fit much better than others with 2 screws) that fit very well on the genuine exhaust, and you can also do a small weld once you tighten them completely (I did it for 5 euros) so that they can't be stolen. Finally, I should mention that you need to be careful not to touch the bumper because it increases the temperature and it is very likely that it will melt part of the plastic or any material it touches.
Clearly, I would buy it again, the durability remains to be seen, although I have no doubts.
