High Flow Crosspipe Ticking? UPDATE NO MORE TICK!

I've read a couple of threads about this problem and it seems normal. But is there a solution to quiet down the sound by wrapping the pipe? I was thinking of doing 4 layers of exhaust wrap on the pipe and hopefully it'll quiet down and maybe create some type of heatshield to so that the sounds will bounce back and forth inside the heatshield. Any feedback on how to get rid of this annoying ticking sound is appreciate. Thanks.

UPDATE: After three layers of High temp 1200 Exhaust Wrap, the ticking is gone and turbo spool is smooth and quiet. Just soak the wrap and begin wrapping. For my own pipe, I already had a coated inside out and then wrapping it. Good luck and cheers!

Boxer tick is not that annoying. This is definitely the crosspipe. Well I'm guessing 4 layers or until I can't fit another layer over it! I'll keep everyone updated.

So that's what it is?!?!. That noise has confused me for a while now. I changed to a highflow crossover pipe at the same time as installing PnP manifolds and heard that new clicking. I was convinced I had a weird exhaust gasket leak but couldnt find it. My dad thought I was crazy and didn't hear anything of the sort.

I feel better now if there are others who have experienced this because I have been going somewhat crazy because I couldn't figure out what was causing that and was just expecting that noise to be a precursor to something going bad.

Sorry, I had to get that out of my system...I feel better now

Yeah, its coming from the flex part for sure. I'm just gonna wrap it up a couple of layers and I'll let you guys know. If my car sounds different in anyway I know right away! We're sensitive to those little things. Other peeps like Pops won't hear nothing out of the ordinary. I'll keep you guys posted.

Just a Note: I used 25FT of the exhaust wrap and about 10 Stainless steel ties. Which was perfect for exactly 3 layers of wrapping and it cured the sound and even the boxer tick to a very very low minimal, not to mention the great heat retention and under the hood temps to a low degree as well. I can barely hear it at all. Cheers on this new discovery!

Yeah I got my exhaust elbows ported/polish and coated along with the crosspipe. The exhaust note and ticking is very noticeable if you do not wrap it. After wrapping it now, it just has a better deep tone, I would not say its any louder in volume just slightly deeper now.

ANOTHER UPDATE: After installing and driving for a bit the car smoked for a bit which is normal. However the bad smell kinda stays for a while, but it is getting better by the day. Hopefully it'll be gone soon.

The Basic Procedure is:

1. Spray wrap with heat resistant spray and wrap quarter inch overlapping onto pipe.
2. Use stainless steel zip ties where needed (I used about 10) for my 3 layers.
3. Start the car and let it idle for a 6 minutes or so
4. Turn off the car and let it air cool.
5. Maybe after 2 hours, go for a drive (It should start smoking pretty good by now)
6. Pray the smell goes away soon!!!

What I used: 25FT of Exhaust Wrap/10 Stainless steel lines. All of this was just exactly enough for 3 good layers to the crosspipe to eliminate the ticking caused by the bigger crosspipe and not to forget the better heat retention. Good luck to you all.
