y-pipe banging.
it really only does it from a stop.. usually a bit past 1/4 throttle, if i start off easy it wont do ****...sometimes if i give it half throttle at 20 it'll do it as well.
Looking under the car it looks like theres enough room, even tho areas I can't even get a finger threw, but if you put like a lot of pressure upwards on all the pipes it doesn't hit anything, there is no more adjustment available, it's as good as its going to get apparently.
Any suggestions? Kinda wish I did poly mounts, im having **** luck lately...
Maybe some people just live with it? If I crank the radio i cant hear it... Haha
Is poly motor mounts my only solution?

I just threw a u clamp with heater hose on mine. Wedged it right under the trans crossmember, which is where mine was banging. It vibrates under your feet slightly at WOT but it worked. I just don't want the hassle of poly mounts, but eventually I'll get them on there.
You can buy the rubber bump stop hangers for the Y pipe but thats more of a band-aid solution to the banging problem....
Good luck bro!

It's worked pretty damn good, it feels like I did poly mounts tho with the vibration, is the outside of heater hose the same tolerance as inside? because i didn't cut it to use the inside or anything, im thinking it shouldn't matter.
I might order the bump stop if this ends up melting or something down the road, or do the dreaded poly motor mounts, reading on here tho, people have had the hose in for years without it melting, since it's made to handle heat.
Might be why I only gained 8hp with full exhaust on the dyno?

1. That Y hangar. In most cases it will work. WOrked for me even though I got the wrong size and used header wrap to make up the pipe diameter. Problem is it forces the pipe into position where it is and even forces the pipe down if you want it to when you tighten it; If you hit a speed bump or scrape the pipe it will bend it all upwards and you have to adjust it again. Or if you bottom out at or near that spot it may scrape the hangar and bend it.
2. Heat the top of the pipe with a torch for 10 minutes then use a bar to flatten the top of the pipe a bit for clearance. This is what ultimately worked for me. I didn't care for the ORY i bent up since my new headers are on their way with a new y pipe I just wanted to see if I could stop the banging.
3. Poly mounts. will be doing them with headers I think this is the ultimate solution and allows you to tuck your whole system up further for best ground clearance.
4. I almost cant believe it helped in this regard but I just installed a smooth SLP bellow and it definitely helped the rattling. Hopefully it doesnt bust the lid before I get the headers installed because my stock mounts are pretty flexible .
