This exhaust meets and exceeded my expectations ! Not too loud , deep and throaty, along with a nice little boost at mid range rpm ! I absolutely recommend this exhaust for anyone with a Nissan titan !

It's food design, easy install, double sided tape was a little dry but 20 min in out and matched with after market cai definitely feel difference, smooth better response and better mileage

Perfect condition , shipped very quickly.

The included crossmember spacer to line to exhaust up helped a lot to get it bolted up correctly with no interference. Everything lined up well I was able to do it by myself, tips lined up perfectly no issues. The tone is slightly louder than stock with no drone which is exactly what I wanted. If you put your foot in it, you can hear it! Cold starts are nice and quiet, you won't disturb your neighbors. My only complaint was one of the clamps for the exhaust tips was defective but I had a spare. Still gets a 5/5 from me!

So far the product has been great and lives up to the advertisement. There is an immediate difference in throttle response and mpg. I am very satisfied other than the instructions were not quite accurate on the location of one of the sensors. A video of installation would be a plus due to the access to the turbo pressure sensor which will cause some extended time to install (better have small hands) and to remove when taking your vehicle for warranty service at the dealer. It was was worth the effort though.

Well packed, quick shipping too!

fit perfectly, preforms outstandingly

Great quality

Excellent quality and fitment.
Can’t say about adding any power just yet, need to drive it more.
Bottom line, Very pleased

Super easy install. Paired it with mid muffler delete, afe intakes. And 93 octane
Sounds like a steamroller. Super fun in manual mode.

So pleased with the quality of this product!

After replacing two radiators, I decided to go aftermarket. Stillen has a good reputation. The replacement radiator was on sale (always a bonus). The radiator fit although the fan shroud needed to be trimmed. I knew that going in. I haven't driven it far, nor are we in the hot weather/stalled in traffic zone, but I have every expectation the radiator will perform as advertised. A purchase with no regrets.

Fits perfect holds up amazing great materials

Awesome quality good fitment and instructions.

I was in the market for a cold air intake for my 2011 hyundai elantra to give it a little more h.p due to the high mileage (300k). As we all know in 2025 there's a million websites to order/ buy things however, Stillen had the best price out of everyone! Thanks again for your professionalism, best price, and fast shipping! Definitely will order/ purchase from Stillen again! 5 star 🌟!
