NEW TO FORMULA (silent thunder question
 

I sold my baja 240 sport last fall and bought a SR-311 the baffels are not cut out in the platform is there any feedback from the formula guys out there does it sound better with or without, my baja had a 550 stroker motor with corsa tips and you could hardly hear your self think let alone listen to the radio. So I don't want it to be anoying loud



Thanks

Needed a better radio!! Lol I took my silent thunder off altogether. I like loud

I cut out the baffles and then installed the round screw in plastic inspection ports on the bottom. That way I could have it slightly loud exiting the square exhaust tips and then If I wanted it louder, unscrew the inspection ports on the bottom of the silent thunder and it is louder yet. Also, had a 419 and remove the silent thunder altogether. With CMI exhaust, it was pretty loud, but never too loud.

38 Fountain..I am going to ultimately lose the ST platform for thru hull exhaust and an aluminum platform in the future I believe..for this season though I think I am going to cut out the baffles and drill some 4" holes in the bottom of the platform..from what I have read it gives you better flow when running but still muffles the sound a bit when idling up river since the holes are under water..where did you get the inspection ports and what size did you cut in the bottom of your platform?

I cut 6 in holes in the bottom ahd putt the inspection screw in covers on it sounds a ton better not too loud but not quiet works good cause I can screw them back in and retain the stock noise level if desired not that I ever will but someone down the road might want to

XFT..do you have any pics of your platform after you cut the holes and installed the inspection covers..I was thinking of doing the same for a cleaner look and the option of putting them back in for the next guy down the road if/when I ever sell her..but to me..Mo louda mo betta!

here is the pic of what I did sry its dirty as hell right now but anyway the inspection cover lid just screws right in there if you want it quiet I did 3 of these one on each side and one in the middle works nice and dosent look all hacked up

I cant get the pic to upload but I used the rwo screw inspection cover with seal they are like $30 ea
easy to install just traced and cut out w jig saw silicone around and its a clean look, works great, sounds a lot better just place 3 acrost back under where the exhaust comes through the hull I think it took like 30 min to install very simple
