Default Exhaust rasp idea!

Hello gents,

So I've had my exhaust for about the last year or so and have been very satisfied overall. However I have a little bit of rasp with my current setup between 3-4k. If I go "WOT" in the appropriate gear it's not a big deal and you hear a slight cross-over for a second or so. It's the times when you step on it in 3rd or 4th and it takes some time to cross-over that its apparent.



Above is a picture of my current setup. My question is if I put a resonator in the mid-pipe will it make the rasp go away between that cross-over point.

My exhaust consists of the following:

HKS carbon Ti 3in
3in piping
Custom Y-pipe 2.5in inlets 3in outlet with 18inch resonator and no flex pipes
Kinetix resonated test pipes.

Here's some video footage done with my Droid a while back to give you a little bit of reference.

It will change the exhaust sound sure. The result is a guess.

I've heard other Z's with HFC and they still have rasp.

why would u get HFCs? dumb idea. one thing to think about is ART Pipes..... With my current set up i was thinking ARTs but im afraid it will change my exhaust note to much. i FINALLY got my exhaust note PERFECT!!! However a few more hp and 2 handfuls of tq would be great also. Anyways in my previous exhaust set ups i think that adding a Vibrant res would def kill most of the rasp
