"Bought a "performance exhaust" for a low rumble exhaust sound. Not a bad system, but only a bit louder than a factory exhaust (disappointed)."

Easy Install, Great Value

"Got this because someone cut out my cat and I decided to replace the whole system. Matched it with an Eastern Catalytic Converter and I am very happy. The exhaust installed so easily I couldnt believe I thought about paying somebody to do it. The Catalytic Converter was another story.... It is fairly loud in and out but its not "ricer" sounding, its quality and I enjoy it. Definitely louder than stock and might not be the best fit unless you want the added noise. I am very pleased with this purchase! I noticed that after I bought it, they jacked up the price. However, I would still buy it at this price compared to twice as much for competitive brands."

Pretty happy with the purchase

Posted on 08/25/2007 by David S. (Franklin,IN)

"It is very quiet, yet seems not to have lost any power over the noisy Midas Ravin system it replaced. Installation was easy, once I got the old system out. Nice mandrel bemds and nice chrome tip. Hangers line up perfectly, but the rip hangs a little lower than I'd like. I'll probably modify it to bring it up closer to the body. They should state somewhere that Doug Thorley and Jardine are one and the same. The box didn't say Doug Thorley anywhere on it, and I thought it was a mistake. I also didn't find any fine print or warranty info other than the "Lifetime guarantee" listed on this site. I did call to verify this, but We'll see if I have a fight in a few years if it starts rusting."

"The system was really easy to install, about an hour and a half. It sounds good, not to loud, but definitely noticeable. I do not know if it helped power or gas mileage, but I am very happy with it. I will probably get one for my 90 Toyota truck. The only problem I had was with the gasket. I was prepared for that after reading other reviews before I made the purchase. Like the other reviews, I went to the local parts store and got a gasket and it worked fine."

"The system went on fairly easy and it sounds good, however I was disappointed by the pipe fitting inside the muffler outlet and the clamp on chrome tip that we had to tack weld on. Poor design for such an icon in the industry."

Jardine exhaust for Toyota T100

1 of 1 people found the following review helpful.

"I've replaced quite a few exhausts over the last 15 years and this was by far the easiest install ever. The fit and finish was perfect, the hangers matched up perfectly, just like factory exhaust. I had the old rusted exhaust off and the new one on in 45 minutes. It's louder than I expected, but a real deep tone for 3.4 V6. If you don't want any cabin noise, don't but this, there is some."
