AA vs VRSF Midpipe

chujk1985 · 01-06-2019, 06:52 PM

What are the pros and cons of the AA mid pipe vs the VRSF mid pipe?

Justin.AutoTalent · 01-06-2019, 10:16 PM

The designs are very different, not so much pro or con between either solution.

Active mid pipe is going to change the tone while increasing the volume and reducing the rasp.

The VRSF is going to just delete the secondary cats, which will increase noise and the standard rasp.

The Active solution is more popular since it pairs well with the Remus Axle Back or Dinan axle back and can also be run with downpipes without producing crazy rasp

VRSF pros: Aggressive price, will get you a louder exhaust tone without a CEL light (compared to catless downpipes another cheap option to get a more aggressive tone).

AA pros: Deep tone that eliminates the rasp for a cleaner sound. Dyno proven to add 10-15 HP

AA sounds great, look on youtube. I have one with stock everything else and it sounds great.

MisterF80M3 · 01-26-2019, 05:33 PM

I have AA. It sounds a little bit louder than stock. It sounds very stock-like.

Glad to hear you like the AA mid pipe

Is it possible to eliminate the secondry cat with a product that doesnt require cutting of the stock exhaust. Also will eliminating the resonator add horsepower or just for better noise.

You can get a full cat-back, which replaces the stock exhaust. The OEM system is a 12 foot long, one piece system.

Popular options without resonators include: FI, Remus, AWE, Active

Just so everyone knows; the AA and VRSF single midpipes are 95% similar. The other difference is the large section of the AA mid is split into 2 on the VRSF.

But both sound the same. VRSF is 1/3 cheaper price too

Please keep in mind this thread was created last year. This was before VRSF released their single midpipe.

All the responses here are comparing the AA single vs VRSF dual.

You are comparing AA single vs VRSF single

I debated whether or not the AA was worth the extra cost, but I chose the AA due to its quality and AA's reputation for solid products. Worth every penny, particularly with the great price I got from Mike.

Some say the VRSF is better quality for this product.

I definitely don't say that. Probably those who bought VRSF say that. I bought a VRSF charge pipe for my previous 335i and there were defects that required work-arounds. Definitely not better quality from my perspective. Also - VRSF makes a single-midpipe design very similar to the AA I've got on mine, but some say the flanges that connect to the downpipes are poorly designed and require modification. No mods required for the AA, which bolted right up.

Ok cause I used to have AA and trying this out this time. I will give my thoughts on the VRSF

I have the VRSF single (AA copy) and it bolted right up with no modifications. Welds were fantastic and overall quality was high including how it was packaged and shipped. No reservations at all about recommending it.

This is what I’m saying. I’m looking forward to it

JayKno · 02-18-2020, 11:57 AM

I have the AA single mid pipe, haven't installed it yet. I only got it because the VRSF wasn't available at the time. If Iw as going to buy one now, I'd go wit VRSF, no doubt. Same thing, just cheaper.

Here in UK people who tried both say there is no difference between two sound wise. Of course as a trader/manufacturer you will be defending own product ;which is right way to do.
