In regards to the slip joints, we actually do this for a couple of reasons.

1) These slip joints allow for easy adjustment during the installation process. Even though these cars are built in large part by robots we find that there are a differences from car to car. We've actually seen some cars where the hangers are off from the factory and even the factory exhaust tips don't line up. By utilizing these slip joints were able to gain a more precise fitment.

2) Thermal expansion- All of our parts are designed to be used and used hard. We know that a large number of our customers will find themselves exercising their gals on the race track. During a 30 minute track session that exhaust will expand A LOT. If we did not have those joints on there the chances of cracking welds is much greater. We have seen some customers weld our exhausts and the thermal expansion has cracked the cross braces, hangers, or even muffler to pipe connections.

If you would like to swap out the clamps to a stainless steel band clamp that is definitely an option, however I strongly recommend you do not weld the exhaust.

Greg the service manger did make an interesting remark. He felt that for my next mod, I should go for Nismo headers , rather than Berk’s HFC. :stirthepot:

The OEM headers were very restricted and the that the Nismo were much more open, this way I wouldn’t have to worry about emission or the o2 light going on and given me trouble!

Appreciate your input on all this.

I have heard that the OEM exhaust manifold is good enough. Thats why I'm on the fence when it comes to LTH's or TP... Can someone else chime in about the oem headers.

Sounds good Alex. You need a camera assistant!

Like others have said, it generally takes 1,000 miles or so for the mufflers to bake in. During the first couple hundred miles or less you may also notice some light dust or fiberglass material on the exhaust tips when you park. This is perfectly normal as it's simply the muffler packing settling in. The tone will change slightly after 1,000 miles and in my opinion become a little bit sharper but it's mild and not offensive in anyway.

That explains it...I installed it about a week or two ago and took it to the track yesterday. I thought it sounded different but figured it was because I was under a helmet until I drove home and it sounded much louder/deeper.

Sounds like you heat cycled it completely.. and it's settled in. Will get a touch deeper.. but still no drone..
