Cobra noise

[Flores8787]

So the following issue started a couple of days ago after a week I had a new clutch kit and flywheel installed.
There is a noise very mild , kinda like a "rattle " that only comes up when I floor it on 5th gear , I can't seem to hear it on 2nd , 3rd or even 4th gear. Any ideas guys? I'll probably take it to the shop this weekend to lift it and look at the exhaust
Thanks guys

Check your clutch cable cover on the tranny. Mine was rattling when I first bought my vert. However, I could hear the rattle "mildly" while the car was idling due to the cover not being installed properly.

These cars have a lot of strange noises, some can be tracked down easily and fixed, others take a bit more investigation. Are you confident you have good gas in the car? The sound you describe, could be a pre-ingnition rattle. If you haven't done so lately, have the tune checked.
