RB exhaust question

I recently installed a full RB dual exhaust on my car. I have noticed how low it hangs and am wondering how you guys overcame this. Did I miss a step or is there something you guys did as in hangers, etc. The back end of the presilencer is rather low to the ground which is caused by the weight of everything, and lack of support between the header and muffler.

A good exhaust shop should be able to weld on a hanger for cheap, the system that came with my spare 7 had extra hangers for that reason

The RB SP exhaust has two spots to add hangers. One is between the front of the
two presilencers. You have to thread something in there and attach it to the hanger
spot that comes off your tranny. The other is at the point where the pipes come
together, theres a tab you can attach a hanger to there as well. Sounds like you just
need more hangers. Mine sits up nice and tight underneath and you can barely
see its there. Maybe show us some pics of how it sits and the hanger setup.

Now I bought my RB SP system used but I think those hanger spots I mentioned
were not added later.

Mine hangs and scraps a little but my car is lowered. I think it fits quite well all things considered myself.

After looking at it I will get a new oval hanger for the back and reposition it to hang higher. Right now it is kind of hard without unbolting/repositioning it to do much of anything. I see the two hanger spots after looking at it a second time. I overall am very happy with the exhaust, I just wish it were noisier.

My car is lower and has the RB SP exhaust as well it hangs low enough that it scrapes on my gravel driveway if I follow the normal driving line and thats with the 15" wheels ,if I put on my 13" wheels with slicks it sits about 3" off of the ground. I guess I look at it as the mass is lower in the car.
