The add a circuit I put in for the exhaust cut out and another one I added to hard wire my V1 are sticking down and blocking the cover from going back on. I could move the V! bit to another fuse spot that is OFF when the ign is off on when car is running. Anyone suggest one that is not near the bottom of this fuse box? The cut out exhaust has to be where it is of course. It's working fine and I REALLY like being able to go loud for a while, then quiet when it gets on my nerves or I want to listen to music and quiet of course in the hood. GM should have made it that way of course but makes too much sense.

Froggy, let me put it this way,
Not a fan of trapping heat of any kind on the cat's, or even blocking the air flow past them, since it will shorten their life.
As for heat tapping down pipe, never been a fan of such, since what the wrap can trap itself. So if reduction of heat radiation is needed, then ceramic coating just does a better job without the fear of trapping instead.
So problem is heat soak to the starter alone since the cat and down pipe are not having problems themselves, and the simple $14 heat shield on the starter alone, solves the problem nicely without all the needed extra work of trapping in heat of other parts.
As for the starter now with heat soak problems, being that is has seen a lot of heat soak to begin with, it needs to be pulled down to be cleaned/greased/refreshend, then the heat shield install on it.
Regarding starter heat shields, it's kind of just luck of the draw that someone did find a $14 unit that works, since before such, were faced with bolt on built units in the $80 range, just breaking metal to make one yourself, or heat blanks that again, can trap debris.
Regarding this thread, since it seems to turned vendor product pimping with a lot of extra products and work to promote sales (that I don't see begin needed to start with due to there short comings long term), I wash my hands of this thread and lets just let it go at that. Simply put, debating with a paid vendor to put anything of their products in an off-color just end up with either the response deleted by staff, or just being ban from the site instead (not mater if the point is valid or not).
Cheers,

I just ordered ACDelco # 337-1201 from Amazon @ $93. I'll do a video on how it goes. Prime delivered "free".
Thanks all.
BTW local Chev dealer wanted $543 & $45 core for what I am pretty sure is the same starter, go figure.
Same one on Rock Auto for $92 plus ship.

Good thread here. I have a 2012 Z06 with 7.5k miles and experience this slow-start when hot phenomenon as well, it is apparently much more common than I was aware. I like the heat shield wrap for the starter but I'm wondering if the starter won't still ultimately get to the same high temps that it otherwise would, and then when it does, fear that this shield may impede the ability of the starter to shed that heat and cool as otherwise it normally would?

If using the DEI Versa Shield starter wrap, it simply vel-cro's over top of the starter and solenoid. The outer skin is a reflective mylar covering that will help reflect ambient heat away. The inside material is a lightweight glass fiber matting to help block the heat from coming thru the shield. This shield also is open on both ends to allow for airflow thru the starter. The catalytic converter shield is design to clamp on allowing an air gap but blocking the direct heat from going directly on to the starter in Froggy's case. There may some cases and situations where an engine or exhaust system is upgraded and produce more heat, or be closer to the starter and cause an extreme heat soak,but our products will help and in most cases cure the issue. Please feel free to contact me if you have any questions.
Thanks, Tim

Bringing this up to date, I am back to thinking the loose nut on the starter (found when I went to unscrew it) is/was the problem along with heat. The nut that fastens the conn to alt & conn to batt both on one stud. Perfect cold start, slow/no hot start. Bad/loose connection. I am going with the original starter (I have a new spare). I am wrapping the cat & starter. Wish luck. Race tomorrow.
I would like any info on who/what fastens this on original assembly? Hard to figure a robot does it. Only 9k miles & doubt it's been touched by anyone since built. Anyone know? I think some guy/gal never got it tight, but was tight enough to roll off the line, problem to show up later, miles down the road.

Hello Everyone,
Tim from DEI here. We get his question a lot. While every application and engine is just a little bit different, typically we see great results with our Universal starter shields. Check out our Versa shield for the original standard GM starter (the big one). We also offer a smaller version for the high torque mini starters or new OE styles. P# 010384 for the bigger shield http://designengineering.com/versa-s...tarter-shield/ and P# 010384 for the smaller shield http://designengineering.com/mini-versa-shield/ . Also depending on how your header tubes run we also like to recommend wrapping your headers or at least the area by the starter. We also offer a pipe shield that clamps on over the pipe to shield heat away from the desired area you want to protect. http://designengineering.com/titanium-pipe-shield/ all of these products are available from Corvette Central or Zip Products. Feel free to contact me with any questions.
Thanks, Tim
