Would like to go halves with someone perhaps as we only need 9" per pipe (thats what she said) for a total of 36" (4 pipe V8) as they come in 72" lengths. Anyone?

I requested a sample for a test fitting but based on the ID, it may very well be a nice easy press fit that slips on with a little silicon on the end. Super simple.

The 3.5" ID version they also have would leave a nice reveal gap between pipe and carbon but adds the issue of centering the carbon around pipe. We would need some form of spacing which probably wouldn't be worth the extra hassle.

 

No strong feelings at all if it's on your car, and I'll do what I can to assist you in implementing whatever mods you want to undertake on your car. I'm just ambivalent about CF (for appearance purposes) and understand that makes me an outlier among auto enthusiasts.

 

Unfortunately, the smallest tube in that list that would fit over the OEM tube has a 4.25" ID and would require a half inch spacer all around. Ideally you could find a tube with a 3.375" ID.

 

I think your dual pipes are bigger than the quad. I thought ours were 3.25" but I didn't use calipers to measure just a tape with eyeball.

This is the list we are referring to: https://www.rockwestcomposites.com/r...n-tubing/45658

That other company has nothing that will work. They have since sent me an email stating that they send out no samples so it's a dead deal.

I am going to get some aluminum tubing and wrap it black carbon to match what I have.

 

If the press/slip-fit works with the 3.25 ID sample, leave it on the car for awhile and get the pipes to full temp to see if the heat expansion of the metal tips split the carbon fiber. Don't try to wack it on with a hammer, but rather cool down the tips with ice packs before sliding on the CF tube.

 

Did you check the links I provided?

 

No, I was looking at the one Polaris first provided. Obviously, just about any size is provided. Now to determine how best to fuse the tube to the tip, given the large temp fluctuations.

 

They won't send me samples as I said as the cf is outside of their sample policy. The tubes are far too expensive to experiment and gamble with so as I said earlier, I am just going to wrap aluminum tubes with black cf wrap to match whats already on the car. I can't even see the color of the carbon other than the pics online. Its probably basic silver weave whereas my wrap is black which will clash hard.

With the aluminum tube, I don't have to worry about failure. By the way, earlier today I drove the car hard then touched the pipes after I got home and they were cool enough to keep my hand on. I would describe as very warm, not hot. I'm not sure they even get as hot as we may be thinking.

All I really need is to get the pipes scalloped, I'll wrap them myself. Anyone have the skill to just do that if I send you the four 9" pieces? I guess I can find a local machine shop.

Appreciate the good ideas though.

 

The V6 pipes may be different. I know my wrap has bubbled just above the pipes when the car was mounted to the dyno, and I remember an early post from someone who was burnt badly by brushing up against the center pipes while wearing shorts.

 

Aluminum has a higher coefficient of thermal expansion that steel/stainless steel, so it could get loose at high temp.

 

I'm dying to see if there is a final solution as I'd like to change the tips on my car. You might check out startech they apparently were working on tips for our car. Not clear what the material is (everything else seems to be carbon fiber). Startech customizes Jaguar F-Type with leather and carbon for Geneva auto show | Autoweek

Never mind, they are black, but interesting treatment: Jaguar Tuning from | STARTECH Refinement

 

I'd hazard to guess that active exhaust in open configuration combined with hard driving will heat up tips.

 

What other scenario is there?

 

Rumor has it, green F-type was seen driven under speed limit in the right lane in a quiet mode. With a turn signal blinker constantly engaged. After such unjustifiable abuse exhaust tip temperature could be alarmingly low.

 

My wife must have taken it out for a drive without telling me! lol

 

When I said hard driving, I meant zipping up and down the street like 50 for a while at high revs to see how hot the pipes got. I'm sure they can get hotter but for what I do I got the info needed.

 

This gent has some carbon fibre tubing, slightly used, cheap!

 

Its a duration thing as well. After driving for an hour or two in spirited mode...ok normal for me...the tips on the quads of mine get very hot. After one such trip I opened the trunk to get plastic bagged groceries out and realized i had a extra bag that fell down and landed on the tip. It melted almost immediately and of course smelled awful. Had the wait for them to cool down an hour later to get the polish out to clean off the burned/charred plastic.

 

Better by far than what happens when you are in shorts and touch the tip with your leg. Did that on bailer when I was young and had to stay out of pools for most of the summer (which really sucked). Oh, and it didn't hurt when it happened but as soon as anything touched the place where skin used to be it hurt insanely.

 

Was on the Paramount site, they have fighter jet tips they sell with their high performance tune but you can buy them separate. Another alternative: https://www.paramount-performance.co...haust-Tip.html
