The title says it all.
I am going to be competing in sound quality audio competition, so the idling volume has to be MINIMAL and no bees in a can any other rattling, and i will not tolorate any ricey sound.

only deep rumbling, no lawn mowers. of course i want the power gains, but if it adds more noise than power, rule it out.

i want to do it all at once as well as a pacesetter sts (and new **** and boot)

so, basically, i want to have the least restrictive exhaust so that the SC and MEVI will perform optimally with only loud growling at WOT.

parts can be y-pipe, b-pipe, cat, cat-back, muffler or any combination of the above.

feel free to flame if this has been asked before, but i couldnt find anything about full custom quiet exhausts.

thanks in advance!


EDIT: BTW, i still need to be able to pass emissions

 

after searching a lot more, i think that maybe a warpspeed (just seem to like it over budget for no apparent reason) y-pipe, and apex'i catback would make a nice combo and maybe a RT or warpspeed cat, please advise on how loud this would (or wouldnt) be and if the cat is needed.

thanks!

 

I have yet to hear anyone else's setup, but after searching a whole bunch I've reached the same conclusion as you... WSP y-pipe (can't even say "budget") RT Cat and either apex'i catback or WSP b-pipe and maybe flomaster or stock muffler.

 

My exhaust setup is a older cattman y-pipe, carsound cat, warpspeed b-pipe without resonator and the stock muffler. I recently added the carsound cat and warpspeed b-pipe. When I just had a y-pipe installed the exhaust had a little rumble to it. Now with the carsound cat and warpspeed b-pipe without resonator installed the exhaust is a couple db higher. Compared to other maximas running an aftermarket muffler I think my exhaust system is quieter. The few hp I would gain with a aftermarket muffler is not worth the extra noise for me.

 

i REALLY like the look of the apexi catback system, not ricey, not too loud, just really sexy , and a y pipe is an essential performance upgrade, i dont really see a reason to do the cat if mine is still working fine, is there a reason but for 2-5HP?

 

I replaced my cat when I did my b-pipe because I had 103,000 miles on my max and the cat bolts were rusted heaps. It was easier for me to cut the cat out and replace it with a new one when I put the b-pipe in.

 

i think i am kinda lucky here since my y pipe was removed last week for my tranny rebuild, so, as long as the cat is in good condition, it is staying... for now
