Hello all. I was wondering on the Mark 5 if anyone just dumps out the the side of the car. If so what did you do. How loud. Did you put anything in the exhaust to quite it down. I like the look of the mark 5 sides and just want to have an option.
Thanks all.
Paul.
See AAron's build thread. He made a muffler and exhaust system just as you described, but his was for a MkIV chassis. I'm not sure the exact same design would work on a Mk V
Mk4 complete kit #9059 ordered 1/19/17 delivered 3/23/17, 2015 IRS, Fortes/DART347,TKO 600, hyd clutch, P/S, 12.88 wilwood brakes front and rear, heater/defrost and vintage gauges
First start and go-cart 4/11/18. Taken To Whitby Motorcars Greensboro, N.C. 2/5/21 for body/paint
To me side pipes are just part of the cool factor of a Cobra.
Are they loud ? Yes. Are they hot as hell and a danger without heat shields ? Yes
My car isn't at the running stage yet but I understand the new MK5 pipes are a little quieter than the old ones.
I'll wear my ear plugs or noise canceling air pods.
My hearing has been damaged I'm sure from kart racing, being around my dad's sprint cars and racing motorcycles.
I will say that AAron's pipes that he built are the coolest thing I've seen, if I was talented as a fabricator as he is I might try that one myself.
I was at a vintage race and there was a real one with pipes like this. OMG it was loud.
The owner brought his private 18 wheeler hauler. 4 289s, a 427 comp, GT350, and a Terlingua Mustang. And paid hot shoes for all but the 427 which he drove. You know, just a little weekend fun. 2 of the 289s took each other out with some heavy body damage.

Are you looking more for a 289 FIA style undercar exhaust with turn outs just in front of the rear wheels?

I had forgotten about this car but I'm guessing this is something like you are talking about.
While it does look cool I can't imagine driving it around or the reaction from your neighbors and your local police. https://youtu.be/F838mLe186A?si=ii2xuGac0hmaFz1X

Nice car, I love the no quickjacks.
Open zoomies, open car, and a sound system. Perfect.
Stupid fast too it appears.
It reminds me of my KTM Supeduke with the carbon fiber straight through mufflers on it.
I started it with no db killers in it and it set off my neighbors car alarm immediately when I started it.
I put the db killers in it but it was still pretty loud, sounded glorious on the racetrack though.
Corner workers told me it was the best sounding bike on track.
Hot Rod Brothers has a car with straight-pipe zoomies. I've driven with that car and in spite of over 900hp, it's relatively quiet at cruise. Not so much when you mash the pedal though!
FFR 5136 Started as a donor...donor guages, engine, trans,etc. Now...TFS street intake,stage 1 cam, GT40p's,24# injectors and 80mm MAF,70mm TB,Z-spec t-5, and PSE Halibrand wrapped with Nitto 555 G2’s. My ever evolving dream car!!
