Only way to know your true gains is to DYNO before any mods. But all in all, not too bad of numbers.

I'm completely sure that your INJEN is taking away from your power though.

 

what do you recommend as the replacement?

 

Z-tube with an 05/06 back (bigger velocity stack) and an Amsoil dry filter (K&N's suck, IMO)

 

How is that even possible? An H pipe or X pipe is what you use in a dual exhaust setup. If you have a Y pipe, that means it joins back into one pipe. So how do you have an X pipe after the Y?

GRD dyno should read low tho, since its the one where they take off your wheels.

is the price for a flash and dyno tune still $500?

 

Yeah Sloppy said the SAE sheets are normally lower..

I paid $550. Got in at 1:30 and she was done at 4:20

 

Maybe you are seeing something I am not. There is no x-pipe anywhere on that page. All I see is an exhaust that goes into one pipe followed by a 1-in, 2-out muffler/resonator.

 

That muffler might act like an x pipe on the inside, thats all that I can think of

 

An x-pipe functions by much more than simply having two different paths merge then go apart again. There is a lot involved in the design of an x-pipe that makes it beneficial.

 

Maybe we can get Tony to show us a cutaway of the muffler used in the TDX2.

 

i know that, what I was stating is that maybe he thought and was referring to that as an x-pipe cause there is nothing else there that could be an x-pipe

 

The muffed has a built in x-pipe in it. I'm not sure how to explain it really. Tony will have to do that part, lol.

 

+1, it looks like a square resonator but is actually an X pipe

BTW, stock intake is ok but people that think the stock revup intake is good because of the larger velocity stack but think other aftermarket intakes with much better velocity stack suck....well, it just goes to show you who the lemmings are on this forum.

The problem with most aftermarket intakes is heatsoak. Handle that, and you'll have much better options than the stock intake.

 

If there was an aftermarket intake that did not induce noticeable heat soak, and had a good filtering element, I would be on it in a second.

A lot of people just run cone filters that suck in hot air :-/
