I just made an offer of $480. We shall see.

I have been dying to get a Fast Intentions exhaust but if this is halfway decent then I can use the extra money for a front lip and stainless steel brake lines.

$480 was declined.

$490 was accepted.

Looks like bottom line is $490. Still not a bad deal if it comes the same way as lobuzz311's did.

I'll let you guys know.

Nice. Good luck! Hopefully it gets to you without breaking out of the box due to their utter lack of packing material!

Thanks for being the test mule, looks like another option, and a good one for those wanting a true dual exhaust for the price of some axle back sets.

Update this as time goes on, would be a helpful addition, and if you want to cut & paste the pic/review post you made and start a thread in the review folder, that would be

Can't imagine it would. Not sure where the xfer case is, but I'm guessing within the Y of the Y-pipe? If so, not a chance. The J2 Y is much shorter to make room for those massive resonators.
Sooo this won't fit a X?

My Top Speed (with bevel tips) will be for sale this week. Just bought new hardware for it. A quick cleanup, and it will be ready to go.

Got mine yesterday.

Packaging was the same but mine seemed to do a little better.









Only one small issue. The hardware pacakge was loose and open in the box and I lost a few of the nuts and bolts through some of the small holes in the box.

So far the exhaust looks pretty good. Hopefully I'll have the same luck installing it.

I should have some time on Monday.

Got it installed yesterday. No issues with the fitment at all.

Only had one issue getting the stock exhaust off but nothing that an air saw couldn't handle.

The build quality is really not bad. I don't know how they are making any money on these at this price. It looks like the piping is of a good gauge and should last.
The welds would be my only concern. Not that they are bad by any means but in the long run that's where I'd start to look for cracks.

As for the sound, it's different than I expected. To me it sounds more like an HR than a VHR. It's fairly quiet until you get into the higher RPM's and there is a little bit of rasp but it's not bad.
The volume is perfect for me with stock cats.

I'd have to say that for $500 you really can't go wrong with it. We will see if the longevity is there though.

I will try to get another vid to go along with the one posted by buzz.

Here's the stock next to the J2








Don't mind my dirty ***. I barely had time to get the exhaust on while my daughter was napping.

I've not made up my mind yet on the cans but it has been a thought.

I know someone would comment on the shoes.
They are my garage shoes and they slip on and off with ease so I can go inside.
They got real bad last fall when I stained my fence.

My only gripe with this exhaust is the tips and if you invest in tips you may as well buy a different exhaust.

I'll try to get a better pic but I'm out of town for a few days.

They are canted and it seems to be intentional.

I may black out the cans if it gets annoying.

I drove around quite a bit today. This exhaust is fairly quiet on the bottom but does scream up top. It's also a lot more raspy than I first thought. I wouldn't pair it with HFC or test pipes.
