What are our current resonated mid-pipe options?

6SPDG82 · 06-16-2023, 07:05 AM

I’m in the market for a resonated mid pipe and wondering if I have all the options identified…

Super Sprint J pipe (and X-pipe?)
AA resonated
I heard Mad was going to offer a resonated mid pipe?

Any other options? Are there any resonated X-pipe options?

I like the increased volume of X-pipes at high rpm but want to reduce/eliminate rasp. This will be with the stock downpipes, muffler and stock valve operation.

Links welcome if you have them.

Thanks!

IRL midpipe

Valvetronic midpipe

MAD resonated single just started shipping, for sure that’s going to be your best value option.

I personally don’t think you need or want a resonated mid pipe though if keeping the oem cats.

I want the slight power gain (~10RWHP) but not a really big increase in volume. My car is also a manual and I don’t want any drone at all.

Active Autowerke offer resonated single and X-pipe
MAD offers resonated single

Like others have said our resonated is now shipping but, if you are planning on keeping the stock downpipe you can really go with either option. Rasp is only really present when you introduce a high flow downpipe.

Personally I would consider our non resonated and a valve controller. I think this will give you most flexibility overall.

I think this video highlights it fairly well. Keep in mind the factory valve is only open around 30-50% in sport mode and its constantly fluctuating depending on your throttle input in some modes which creates different tones.

Everyone has different tastes and different goals so if you want it slightly smoother sounding go with your gut.

Thanks, is this video with stock valve control? (No exhaust valve controller?)

I’d definitely start with a valve controller and if that isn’t enough IRL midpipe to pair up, or any other midipe you might like.

Hey thanks. I’ve already opened the valves (manually) and while it’s a relatively small increase in volume I prefer the stock valve operation. A controller is not what I’m looking for. I’m primarily after the ~10RWHP and a bit more volume. (I just don’t want any rasp or drone)

You also get 24 lbs of weight reduction

Steveo · 06-17-2023, 11:36 AM

Scorpion and Milltek have options.

Nkr15 · 06-17-2023, 12:27 PM

I have the esienmann resonated mid you can hear it in the thread

Can you share pics of the resonated version? Wanted to see the size of the resonator. Also what diameter is your single mid?

Thanks!
Chris

1. You really think you're going to feel 10 RWHP on this car?
2. You're confident that you're going to get 10 RWHP from a midpipe change only?

I felt 10RWHP on a 700RWHP car so yes. It’s been dyno’d over and over again to provide anywhere from 10-14WHP.

(I’ve built and raced cars since ‘94)
