Exhaust Question

[sy34010]

OK here’s where I’m at. I have a 4” kanaflex intake, green wheel, jfizzle XS IC, 42# injectors and a 15/20r. I was initially going to try and make with all work with the stock exhaust but after hearing the thru hull and seeing how much clutter is eliminated I’m think of going with the Riva setup. My question is what the quietest possible setup when going with the through hull? Riva? Gibson? Some other combo? In honor of Mother’s day I’m worried about keeping mama happy when she rides the RXP and I know mama won’t be happy if it’s over the top loud.

Also if I do go with the Riva rear exhaust is all I need the kit itself http://www.4-tecperformance.com/index.php?main_page=product_info&cPath=18_3&produc ts_id=301
and some OPAS block offs http://www.4-tecperformance.com/index.php?main_page=product_info&cPath=18_1&produc ts_id=352 ?

Thanks for the input.

I would think stock water box. I think the Gibson muffler was louder than the stock box exiting out the back.
I have run stock box out the back and it is not that loud.

Thanks, that's what I suspected but I haven't had the opportunity to hear one in person. Trying to get his done in time for Memorial Day weekend.

I agree too! The stock box run out the back would be the quietest but one notch above stock with the resonator. Next would be the Gibson, then the shorty WB. I am sound concious too. My wife dosen't like the sound, either.
