there is no way those little holes with the fake chrome tips poking through, with the flimsy plastic bumper that BARELY surrounds them with a little piece of plasic at the bottom, is going to stop your car from taking flight, if it was going to happen. I wouldnt worry about it.

I feel dumb quoting myself.....but I have to say I've had joez exhaust on my car about 6 months or so. Loved it. My only gripe was the stock exhaust tips, which I didn't like. So I bought an iss exhaust. Just swapped it out. Have some good and some bad comments. First, I found the joez packaging for shipping far better. I was missing hardware from both the joez and the iss, so no winners there. I had a few missing bolts and nuts from each. No biggie, just annoying. Finish and welds are both pretty dan good. I'd say advantage Joez though. I had a lot of residue inside and around iss piping. Should have been cleaned up prior to shipping. Fitment is hands down going to joez. Iss hits several areas of heat shield under car. Had to remove one to keep from rubbing and rattling. Overall, they are both very well made. I'd say advantage to joez. If only they made an optional oem tip removal and dual exhaust. I'd say it comes down to preference on stock tips to be honest. Also, the burnt tips on the iss were a little bit of a letdown. It's very ununiform. Hard to see on the car though, so I can deal with it. As far as sound, they seem the same at idle. But once you get on it under load, iss is much louder with more of a snarl. Joez seems to be a deeper, smoother sound transition as you progress thru rpm's. Iss turns heads. It sounds like you just unleashed a pit bull that's been on a gunpowder diet. It's like all hell broke loose. I love it. So for me, sound advantage totally to iss. For me, n/a gains are never much to brag about. From my old is300 with pointless boltons, to the isf with boltons, none are tremendous gains. So for me exhaust is an aesthetic gain. I'm happy with my transition. Hope this helps if noobs are debating iss and joez.
It sucks you were missing bolts, i know exactly what its like when that happens
.... but i am here to say, my ISSforged exhaust wasn't missing anything. It was self explanatory, but i will admit that a set of instructions would be good. I hate getting a product and not having any guidance......just have to guess and hope for the best. Lucky for me, i have experience, a lift and i am good at putting puzzles together. 
One last thing.....the ISSforged exhaust doesnt hit "several key areas of heat shield", it hits one......and that part is supposed to be removed.
my review on this exhaust is that you will NOT be ready for how loud it is when you first fire it up.......but......within 10 minutes, you will be fully addicted to the sound. The first start of the morning is REALLY loud.....but it mellows out once warmed up. I have had nothing but jaws dropped, snapped necks, and compliments ever since i got my new exhaust. I love it..

mikefate -thanks for the comparison review. If the ISS turns heads did the Joe Z not? I've yet to hear a Joe Z in person. At the Baltimore meet everyone had headers with ISS or Joe Z.

This review really helps my decision. I'm guessing since ISS is in Miami and I'm an hour from them I'm probably going to ask them to do the install. I doubt I'll be missing bolts/screws then

Hey ISS......Can you chime in to let us know what to do if we have headers already and need to quiet down the exhaust?? I have tried installing 2 vibrant resonators then I switched for the oem cats...still nothing. The exhaust is so unbearably loud inside the car between 1500-2200 rpms it is unreal. I love the iss look with the tips, but I need an honest solution on how to fix this. I dont want to remove the exhaust, but to daily drive this car I need it quieter. The drone is sooo bad in the car it sounds as though pieces of my car interior are falling apart and starting to vibrate. Im basically going back to oem exhaust with sikky headers this week unless something can be done with the drone. I noticed your earlier models have an additional muffler after the x-pipe....is there a way to get something like that installed on the newer versions? Help please. When passengers get in they look at me like Im crazy and usually say something along the lines of "how can you drive with it this loud on the inside...."

On another note. Our system is not mass produced. It is hand made to order. We have had a very hard time finding a box that fits properly so we concentrate our efforts on making sure the system doesn't get damaged in transit. The box might not be nice but the system gets there in one piece. This has not always been the case and I am very grateful to the IS-F community for working with us during the development of this product. The residue in the system is part of it. We have installed a lot of other exhaust and have noticed that custom exhaust tend to have more burn off then exhaust produced in quantity. Trust me its a pain to get the welds to look nice with that oil there. We try our best to drain them before we start the manufacturing process.
On the burnt Tips option. Your system was the first one. Since we didn't hear anything back we figured you were a happy customer. The burning is being done by hand. There is no way to make them look alike. This in my opinion is a novelty. I dont know if you've noticed but as the temp in the tips increase the color changes.
Guys if there is any concern with our products please let us know. We have had issues with other members and you can ask them all... We stand next to our product with pride and honesty. It's the way we do business.
Glad you like the sound and the system and please contact us on the burnt tips issue.

We are in the process of working on that! I drove one with Elite headers and it's LOUD!!!!! What we don't want to do is sacrifice performance on our track system. So we are releasing a Track / Street Hybrid System. It will be loud when you want it to be loud and quiet you need it to be.
