VRSF and AA Equal Length Midpipe Question

[Zubia3]

I got VRSF downpipes and a non-resonated equal length midpipe installed from a shop near me this past week. I noticed the rasp at 1500-2000 RPMs is unbearable, I was wondering if anyone else had this issue. I was trying to find a fix to the rasp, would I be better off with resonators on the midpipe?

The formula is easy enough to find if you search...

If you have catless DPs, resonated EL is recommended.

Yeah I have very minor rasp with my resonated EL and it sounds beautiful 3K+. I can't imagine not having resonated and that sound being amplified. Ordering a set of resonated pipes is probably the most cost effective way to clean up the sound!

I think you should either switch back to stock downpipes, or get the AA resonated EL midpipe and see how you like it from there.

Agreed, anytime you combine cat-less downpipes with a non-resonated mid-pipe you really lose the clean sound.

As someone who is cat less but is probably going to go back to cats for a bit is there a downside to resonated mid pipes with stock downpipes?

There is a good chance i go back catless in the future which is why i was wondering.

The resonators in the midpipes do nothing to hinder performance as they are 100% straight through and only help with cleaning up sound.

Active now sells just the resonated sections of the midpipe for $500. I'd order those and try and sell the unresonated pipes here on the forums.
