Exhaust note for VRSF downpipes + stock catback

Posted this in another thread. Sounds pretty good to me and I didn't see any other videos with this setup so I thought I'd post it if anyone was looking into this setup.

upgrading the downpipe is the most economical way to upgrade the exhaust sound

Before installing the DPs I was already planning on what catback setup I was going to get. But, after hearing just the DP I decided against getting anything else.

Has the DP thrown any CEL? I was looking into getting VRSF as well. Did you get catless or cat'd?



Thanks.

Catless. It did throw a CEL even with the spacer that people say fixes it. I haven't looked much further into fixing it. For now I just clear the code if I bring it in for work.

You can try the longer 90 degree spacer... when I first got my catted one I used it and it was too lean. I had to go with the short straight one.
Maybe the 90 degree one is made for the catless pipe.

It was one like this:

Yeah, I am running the 90 degree O2 sensor. Maybe that longer one will fix the code.

I can vouch for this setup. Before, i had a VRSF catless dp paired with a dinan midpipe and AP intake. Obnoxious and trashy lawn-mower-type sound.

Took out the dinan midpipe to replace it with the stock dual resonated one, and now it sounds beautiful. Wish it was maybe 20 or 30% louder, but the note and quality of the sound is now amazing.

Highly recommend the AP intake though! It is such a vivid and nicely loud sound, and perfectly compliments the stock exhaust w/ catless dp. Everytime you let off the throttle, all you hear is your turbo whistling, natural burbles, and the intake's mean sounding woosh.

Update. I did the MHD BEF + JB4 and I've drove around 500 miles with no CEL coming on. Still using the 90 degree angled spacer

Which spacer are you using because I am about to purchase a VSRF catless dp? I have BM3 as well and am currently on STG 1 93 OTS.

Although it didn't work at first, only after the MHD BEF + JB4. YMMV
