i beg to differ. i have had my car next to an aps 3" car. quiter at idle, and definately quiter under throttle. but not sure if you have had the chance to hear mine yet in person sharif

 

I havent scott. I am only going by what my customer's say, and we all know how a customer's perception of sounds can differ. The APS has one set of mufflers, and one set of resonators. Does yours have a resonator, Scott?

 

Sharif-
I can confirm Scotts is slightly quieter than my APS with 3.5" down-pipes into the 3" dual. (until his wastegate tubes sound off) LOL
If you're trying to make huge power, they're both great. I'm content to be at 562whp and am going with the Greddy. I'm hoping for a little more subdued exhaust note and fewer dirty looks from my neighbors......

 

So you haven't received your EvoTT replacement yet?

 

Scotts has a resonator. Its quieter than my APS 2.5 TD w/ straight pipes, but its still loud :-D

 

Nope. First they shipped me the G35 kit, then they shipped me the damaged Z kit. It's been two weeks and they haven't even picked-up the 2nd kit for return, let alone shipped me a replacement

 

ya sharif, the resonators are a massive 6" outter dia. and ceramic packed, so they never blow out. they do stick under the crossmember about 1/2-3/4", but i personally have never hit mine due to the fact they are so close to the rear tires, and my car has been lowered roughly 3". helping to make it quiter is due to the larger resonators, and the X pipe that raises muffler and resonator effiecientcy by 60% due to giving each sound wave 2 different paths to follow.

surprised you havn't heard one yet. i can guarantee you havn't heard a Z sound like mine, lol. V-8 idle, porsche/ferrari after that.

 

Yup, the 3 inch cars sound like a Viper...at least mine does.

 

LOL Yes it does

 

greddy makes it that way so it'll work with the stock cats.

if your keeping the cats any dual exhaust will do, since they'll be the "choke point"

 

Sharif-

i remeasured that little kink in the evott pipes right before the cats..

they are 60.7mm ~ 2.39"

hope that helps
