Hot Hot Hot

[Lynchyy]

Anybody else's cabin / driver footwell get VERY hot on a long drive? I would say uncomfortably hot. Not burning, but not just a warmth either.

My foot well and transmission tunnel would get very warm after a sprinted drive, marked improvement since heat wrapping the downpipes and y pipe.

Ahhh nice !! Something i will probably invest in. Also noticed it was crazy hot just below the drivers door. RH under Sill.

You got exhaust valves mate?

No matey

Please explain to me the nature of those pipes/chambers running alongside your cat pipes 😂

I’ve just swapped in my hfcs, only just put head wrap on them as Oem cats “had” some of the heat shields left, I did notice a bit of excess heat but at the same time that was only if I did a long drive

I ask the same question what are the extra pipes for

Apologies. These are Motordyne ART pipes

Motordyne ART pipes are for increased power and torque without the drastic increase in loudness normally associated with test pipes. This is achieved by the attached resonator tube that is precisely tuned to dampen out the unwanted frequencies.

I have a quarter-wave pipe I had made for a specific length on my exhaust to cancel out drone between 2k and 3k. Sadly I also need a different length one for 1.5-2k.

Ahh okay that makes sense now, from the picture they look open and look a bit like screamer pipes 😂 all makes sense now
