everybody, do I need a heat sheild around the exhaust pipe under the body???

[himalaya]

Hi,I just removed the rusted heat sheild under the body, becaust it made a noise at 2000 rpm. The questions are what that part is for, and if I need install the new part around the exhaust pipe? I found there is a fabric ribbon on the market, which can sheild high temprature, do I need it?

thanks so much for help.

I suspect that Nissan would have not put them on if they were unimportant-at least some of them.

It is possibly to keep transmission from getting a lot of heat thrown on to it. transmission coolers are often recommended, so this would mean that in theory it could do something.

But could you just switch to synthetics? or is it enough to really matter? Lots of people have them removed. I took mine off up to the high cat personally and left that one.

The wraps might be just the ticket. One thing for sure...the rattle sucks.

There is a thread about this somewhere...I ripped mine off years ago and as was mentioned, many others have too.

i tried taking my exhaust heat sheild off to, but the top and bottom were welded together anyone else run into that problem.

i broke all the bolts out but its still on there and now it sounds worse haha.it squeals from like 3000 to 4000 rpms. and sometimes at 2000-2500rpm and getting worse lol oh and it rattles when it idles sometimes. yea its bad.

should i just break it off?

Too Funny. I literally did this yesterday on my 98 Q, and was wondering the same thing. Planning to put some kinda heat wrap in the spots where the shields were. They were just too annoying. They were already split and I just took a hammer (carefuly), and knocked them off. Hope that suffices!
