Heat shielding for high flow cat
 

My interior has been getting noticeably hotter since I installed the Bonez high flow. Anyone manage to fab some heat shielding to prevent this?

Is this a new or used Bonez?

The first thing to check is to see if you have the insulation material around your shifter. I never noticed any additional heat from my Bonez cat over the stock cat. The only additional heat I ever noticed was from the transmission during track events.

on a first get, I wrapped a cat with header tape.

Didn't seem to have any negative effects.

I didn't notice any heat increase with my Bonez either. Are you sure one or both of the small heat shields did not fall off? One of mine fell off.

I bought it used from a forum member. All I recall is seeing red paint around the shifter every time I have been in that area. Any suggestions for insulating material? The plastic gets warm to the touch. I'll pull the shifter and double check, but I don't think there is any insulation around that area.

Hopefully, it's not clogged. ;)

The insulation? I'm sure someone on here can recommend something other than OEM, but I would recommend just calling Ray. :) I believe the stuff is pretty cheap, under $10. There should also be another cover as well which is a rubber coated metal cover. If you don't have both, get them from Ray.

Note that a stock cat has 3 or 4 layers of shielding plus a layer of insulation on the cat, in addition to the air gaps. It would be tough for any aftermarket cat not to radiate more heat than a stock cat.

That being said, you can reuse the stock cat's shielding on a replacement. It will take some fab work, but its not that hard and works very well.

And make sure the heat shield is secure around the cat itself or you will have a nasty metallic rattle idling at red lights which can be very annoying.

I whipped ass at an auto-x last weekend with it. I was making full boost, so I doubt it's clogged. I'll call ray and order some insulation. I'll also pick up some DEI wrap. That seemed to work well on my downpipe. I don't want to bother with fabbing the old heat shield on if I don't have to. I'm trying to keep the car nice and light.

Thermo-tec makes some sort of product to warp mufflers.

Look at thermotec.com and check out p/n 16500 Muffler/CAT Heat Shield or p/n 11630 Clamp-In Heat Shield.

Thanks for the link. I may just give that a try instead of the wrap.

Never mind, nobody seems to want to carry it.

Check out this thread for what I did and some pics. There should also be a 1" thick green felt piece over the rubber seal in these pics:

Something like the stuff in your link would be great to install in the tranny tunnel. Overall, I would prefer using some self adhesive stuff like that in the tranny tunnel under the car than what I did in the interior. That stuff had a slight odor that stuck around for a while.

The pic isn't exactly lit, but it looks like you draped it over the tunnel and cut around for the shifter?

Speedzone24-7.com is the warehouse distributor for Thermo-Tec. I've found their prices to be a few dollars cheaper than Jeg or Summit for the same products.

Outstanding. Thanks. I had even tried by part number and had no luck with JEGS or Summit.

Larz, I would just deal with getting the stock parts and going from there. The stock parts may provide what you need without going to extremes.

That is correct.
