PE with quads step in

napeHbNYC · 11-10-2013, 11:27 AM

Hey, guys, looking for the next thing to do with the car and entertaining the idea of going quads with DD diffuser. I currently have PE with DPs and sec cat delete with 4" single tips. Those who switched to quad, did you sound changed? I love the gurgle and popping so would like to keep it. If I loose that than might be just getting a DD diffuser for the single tips.( tried the search but no dedicated theread, just single posts here and there). Thank you.

How did your PE exhaust change when you did the DP's? And then from that to the sec cat delete?

The sound will change. On my last 335, I switched to quad tips on the stock exhaust and it got a lot deeper. I actually didn't like it.

When I first welded on the quad tips, the note changed dramatically. It sounded a lot worse.

After ~5000km, the note came back and sounds even better than before. Not sure why this happened but I am in love with the PE again.
