J2 Engineering® - Exhaust Systems

I have installed this exhaust system on My 2005 Chevy cobalt ls. It was super easy to install and has made my car 3x louder than before!

When I got my J2 Catback exhaust system it came in to pieces with no instructions but I would highly recommend this exhaust if you want it not to loud but just right its perfect for a Gen 2 Scion tC .

Has a deep nice tone, but isn't obnoxiously loud. They look nice on the car as well as sound great. Think they're worth it.

So I've had this installed on my 2006 Nissan Maxima for about a year and a half now and its held up to the snow and salt of Chicago winters. It greatly improved the sound of my vehicle, there is not really any drone inside the passenger cabin. It's loud when on full throttle, but in all other instances subtle enough to drive around without annoying your neighbors. I combined it with cold air intake to really get a more powerful yet refined note out of my engine.

Overall, I'm very happy with the final result. I'd definitely recommend. Install wasn't difficult, but it wasn't exactly fast or simple either. Quality materials with a high sheen finish - looks just as good as the pics, and the sound itself is really good too - moderately loud (but not obnoxious) with a raspy crackle on downshift and deceleration. Can drone a bit on the highway since these cars are geared low - but it's definitely manageable. The bad.... let's start with the packaging... The box it came it was cheap thin unmarked cardboard and it was really beat up. Like bad. Holes in the box, squished corners, ripped tape, the whole 9 yards. Then upon opening the box, I found no real packing for protection inside either. Three pieces of pipe, a pack of gaskets and bolts, and a muffler wrapped in single layer, thin bubble wrap. No foam or paper space filler, no install instructions or stickers... Nothing. Just pipes in a box. None of it actually appeared to be bent, scuffed, or otherwise damaged though, much to my surprise - but my first impression wasn't good. With no instructions coming with it and nothing really online about it, I wouldn't recommend installing it yourself it if you've never done an exhaust, but it is pretty straight forward if you have. Removal of the old is always the worst part. Fiat uses some very interesting/frustrating hangers. Install itself wasn't too bad, except you have to reuse the original bolts from the cat to mid-pipe... Which are probably badly rusted if your car is more than a couple years old - be careful removing them!! The other thing that made the installation difficult (time consuming, anyway) is where they put the flanges and pipe bends. A few of the flanges are at ridiculous angles where you can't use a socket because of the way the pipe bends. After it was on, I noticed the tip doesn't stick out. At all. Kind of disappointing because it's a really nice looking tip, but not a huge deal. Aside from installation and packing gripes - it's a heavy duty 304 stainless that looks amazing and sounds even better. After all, sound is why we get pipes in the first place, right. You won't be disappointed with this, it sounds like a micro rally car!

Great fit & finish, not loud at all. Mechanic installed it, checked for leaks and gave it a thumbs up as I drove away. Can't really tell if there is a performance increase, but it does sound nice and raspy. Doesn't drone either...worth the price of admission! Nice chrome tip too.
