Most of those heatshields are just barbie for guys. Mostly dress up without a ton of function. The cobb and grimmspeed are nothing more than bling but th eperrin has a few bends over the top that should help you keep heat down.

Just as some added protection I would look into some thermal managment foil. DEI makes a nice adhesive backed product thats good for heat up to 2000 degrees, Reflect a cool I think. Ive used it for airboxes and the like and it holds up really well.

Id love to see what it looks like with the cobb downpipe. That might be a nice upgrade over the cobb unit.

yea, i'll second what arctic said. most aftermarket heatshields are just bling and dont actually shield much heat.

cutting the OEM heatshield to clear a bellmouth DP works better than any aftermarket heat shield.

either way you should also wrap your turbo while your at it: How to wrap your turbo - NASIOC this worked great for me :) and super cheap. you can split the package with a few buddies as theres enough for 4+ turbos in the $50 package.

Don't forget the underside of the heat shield.

If you want to use https://www.rallysportdirect.com/part/heat-isolation-heat-wrap/dei-010392-dei-reflect-a-gold-12 It goes on the underside of the heat shield. This is the most effective and cheapest method.
