I don't understand the function of the two 180 degree sections of tubing above the exhaust pipe at the rear of the system, above the tips??? Do these open pipes let sound out into the area where the stock resonators were?

They are blocked and some how help with drone. I took mine off and the drone was retarded and unbearable. I put the J-Pipes back on and im back to being drone free.

I just got off the phone with Jeff at Solo Performance and asked him about these 180 degree pipes. They are call "J" pipes and are size specific for Challenger engine size ie: V6, 5.7, 6.1, etc. They negate drone be taking some of the exhaust pulses up into the 180 bend, then hits the capped end and returns into the main exhaust pipe. This meeting of impulses from the J pipe and main exhaust pipe negates the drone.

Knocturnall, you proved this fact when you removed the J pipes and state the "drone was retarded and unbearable".

Very shortly I will be buying and have this system installed replacing my current system of stock exhaust with the resonators deleted, the big bulky boxes at the very rear of the stock exhaust system just ahead of the tips. This system has a very nice sound but the drone between 1750 and 1900 rpm is very noticeable. Wifey no likie...........

Wanting sound without drone was the main reason why I went with the Solo w/ J-pipe on my 6-speed and I haven't been disappointed. I love the system, the sound, and the fact that I can cruise on the freeway and have no drone whatsoever.

Triz, I just edited my last post to read resonators deleted. Like in my signature, I have the stock exhaust with resonators deleted.

Old vs new on mine. I'm sure yours sounds different since you're an automatic and you don't have headers, but thought I'd toss it out there for comparison.

Gotcha...makes sense. I did the reso delete too intially (except with Super 40s mid-body). Wife is much happier with the Solo. No more drone headaches...
