Our new Borla went in veey easily but the gasket that goes between the cat and the pipe going back was not included. The muffler was louder than we expected too. I had asked for a muffler that sounded close to stock. The muffler is loud and proud but nowhere near stock. Oh yes the car seems more powerfull too.

Cat back system is everything advertised. Delivery free and on time. Installed by local muffler shop in less than 30 minutes. Looks and sounds great. Pricey? Depends. It works for me.

Way better than stock

The difference in power is great. I really noticed a big gain in power. My issues are Autoanything sells a supposed C.A.R.B. product but when u go to put on the unit, first they want you to delete the second cat and that wouldn't be as bad as the piece is to short to even do this and the straight pipe section is backwards so you got to cut the flange off the old muffler to make the part fit and no new gasket is included. I think for the price and the hassle its not that good of a deal !

Didn't fit

Didn't fit despite being the product supposedly for my vehicle. Luckily a local shop could weld and extra section and seal up an o2 sensor opening that wouldn't work for my car (the old one could be used thankfully).

Sounds great! Front pipe was not direct fit. Need to cut and weld for O2 sensor to reach.

Best exhaust option for the money

As everyone knows, its a pain to work on exhaust systems. With that being said this exhaust went on with very few hiccups. Everything ended up fitting together properly but i suggest chainging all hangers when chaning the exhaust.

Good exhaust, but I expected more

After cutting out the old exhaust I went to install the borla. After searching through the entire box, I was dissapointed to find that borla hadnt included a gasket for the front of the cat. converter. I went down to toyota and got a new one for 12 bucks, but when I tried to fit it onto the borla pipe it wouldnt fit. I had to stretch out the gasket until it would fit (which took a while because i didnt have the right tool for that). Other then that it took like 20 minutes to finish everything else. It has a nice rumble and isnt too loud at highway speeds. Helped preformance a lot too.

I purchased the Borla Exhaust System to help with my gas mileage. Between the Cold Air Intake and the Exhaust System I have Noticed a drop of about 300 RPM to Maintain the same speed of travel which saves me fuel, so I feel it was a good investment. I did not recieve the free gift but thats ok because I have plenty of hats already.
