Lynchyy Posted August 5, 2021 Share Posted August 5, 2021 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. Quote Link to comment Share on other sites More sharing options...
davey_83 Posted August 5, 2021 Share Posted August 5, 2021 My foot well and transmission tunnel would get very warm after a sprinted drive, marked improvement since heat wrapping the downpipes and y pipe. 1 Quote Link to comment Share on other sites More sharing options...

Azurez33 Posted August 11, 2021 Share Posted August 11, 2021 Please explain to me the nature of those pipes/chambers running alongside your cat pipes 😂 Quote Link to comment Share on other sites More sharing options...
Azurez33 Posted August 11, 2021 Share Posted August 11, 2021 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 Quote Link to comment Share on other sites More sharing options...

These are Motordyne ART pipes https://motordyneengineering.com/product/advanced-resonance-tuning-art-test-pipes-2/ 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. Quote Link to comment Share on other sites More sharing options...
msitpro Posted August 20, 2021 Share Posted August 20, 2021 http://www.vk2zay.net/calculators/helmholtz.php https://wilhelmraceworks.com/blog/killing-drone 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. Quote Link to comment Share on other sites More sharing options...

Ahh okay that makes sense now, from the picture they look open and look a bit like screamer pipes 😂 all makes sense now 1 Quote Link to comment Share on other sites More sharing options...
