V&H Straight shot baffle issues(?)
So, this is my first post. Want to leave with how much I love this form it's been very helpful. Especially with installing a nautilus horn. Now it's my issue. I bought an 05 C50 with Vance & Hines straight shot pipes. They had the standard baffles with them which I found to be a little loud for my taste. After looking at several reviews of The Quiet Vance & Hines baffles I didn't I think that it would be worth the $100. So, my cheap ass went with a universal set from Amazon.com.
They didn't quite quiet it down but it gave it a much deeper noise which I liked. However, when I would accelerate forgive a rather loud WAP WAP WAP WAP WAP WAP WAP. After I let off the throttle and would maintain speed it gave a really nice deep thrum that I liked. So, I thought maybe removing the fiberglass wrapping would let it breathe more and eliminate that rapid succession of womp womp womp. Fortunately it did and it gave it a wonderful pitch that I love. Unfortunately, it created a chirp. Now the chirp only happens in very slow acceleration or deceleration. Occasionally it will happen at certain speeds but usually goes away with it open throttle. I thought maybe it was caused by the gases trying to escape through the tight end cap so I drilled 1/4 inch holes in the end cap towards the end of the exhaust. This helped a tiny bit but did not alleviate the issue. I should also note at this point I had them secured from the whole closest to the end of the exhaust. From doing some research I found this sound could be caused by an exhaust leak which I thought maybe the second hole further up from the end of the exhaust. I tried moving the exhaust to the second hole and blocking the 1st hole which did not fix the issue unfortunately. The Bell ends do seem to fit tightly and some areas in Loosely and others I'm wondering if the chirping is caused by friction in the metal vibrating between the exhaust tube and the baffle or if it could be gases spreading out the split side of the thin stretch of the exhaust that is perforated. Does anyone have any insight to this issue? Should I just buck up and spend the money on the Vance & Hines quiet exhaust? Or just put the fiberglass wrap back on and be done with it?
