Nice deep tone, I couldn't be happier with this exhaust. No annoying noise from inside when your cruising. I would definitely recommend this product to anyone with a civic si.

easy install, slightly lower tone than stock and performance gains are real. No one would be disapointed with this choice.

Installed in 30 minutes, looks great... but most importantly it performs well and the sound is great. It isn't overbearing or too loud, and has a very throaty/sporty resonation that sounds great. It was installed with the downpipe and an Injen CAI at the same time, so the power increase was noticable due to the combination of the 3 items.

This exhaust is beyond amazing. Noticeable mid and high rpm power gains, and the,low range does NOT suffer one bit! Sound quality is immense and crisp. You can tell its a full exhaust and not just a loud muffler. And the kicker... full economy has increased by an average of 2mpg! (I also have the Injen Cold Air Intake SP1836 installed.) 200hp!

I was initially very excited when I received this system. It looks gorgeous, with superb build quality. I was also very pleased with the ease of installation. The sound is a different story. It sounds very similar to stock at idle. at W.O.T. is sounds good. The problem is at highway speeds, it is unbearable. It is not so much the volume, but the resonance inside the cabin. After 80 miles, my ears actually hurt and I had a splitting headache. The car is now unusable on the highway. I recently purchased a Gibson exhaust for my Dodge Ram from AutoAnything. That exhaust was one third the price of the Ingen system and it sounds excellent.

Well I got the cat-back injen SES exhaust for my 09 Lancer ES Sport , and the only problem i had was with the down pipe. Injen doesn't provide with a stud or bolt to block the unused sensor in my car so it took me a while to figure out whether they didn't send it by accident, they sent me the wrong pipe, or it's supposed to be like that. Anyway, i installed it with no problems and it sounds really good. Deep tone, but in my opinion, it is NOT a mild exhaust. i hit 2k rpm's and already people turn because the exhaust is so loud lol. I live in VA so everyday i'm knocking on wood hoping I don't get pulled over. Other than that it's pretty good, and i did get better mileage, and you can feel a little more hp and torque at the higher rpm's.

Amazing sound. I can feel a slightly better response when I hit the gas. With the injen CAI its awesome

I love this exhaust. Not to loud! nice sound. Wish i knew it was coming from ingen direct before i orderd. It took alot longer to get and i didnt receive notice until 4 days later that ingen didnt have. took over two weeks to get.
