In case anyone was curious. I was screwing around today and unbolted my muffler. A bit raspy for my liking. Lol That and the neighbors likely hate me.

Sounds great though. By the sound of it, the muffler is the biggest problem with not getting engine noise eh?

1.4L "Straight piped"

Indeed. I might put a straight through on it next month to see if it's a little more tasteful than that vid. So much more turbo sound and crackle. I love it.

Resonator is the one to blame here. I first cut my stock muffler because I was in the process of building my 2.5" catback . It was still quiet. After I removed the resonator that's when things loud.
Just last week I removed my second cat and finally finished exhaust and man removing that second cat made a big difference in turbo spool time,sound and also turbo sound at exhaust pipe.

Ah well the ZZP muffler is still pretty massive. Close to same as factory. I haven't run a resonator since I got the car. Just realized I would have to buy a new mandrel bent piece if I wanted to add a straight through muffler. That could be a bit, but if I do I will update with another vid.

Mine was completely straight piped for a while, don't really care if my neighbors like it or not, I don't like when they're throwing loud ass parties at 2am so I kinda did it as EFF you to them cuz I leave home at 5am lolol I now have the 200 cell secondary cat in there, its still just as loud just a tad bit smoother. I also have a god awful exhaust leak right now that I'll have to get welded and hopefully it'll sound much better after that haha

Lol Funny you say that because I ended up disconnecting the pipe and tying it up. Still have the muffler to look legal. Lol It would be cool to get one of the on/off mufflers.

They are pricey no? I have a stainless exhaust and nobody around here touches stainless.

I looked into those motorized cutouts. Wayyy over what I'd be willing to pay. After much deliberation I decided on a Flowmaster 10 series. It's a baby of a muffler. Just enough to make my exhaust not deafening. lol

A video a took about 2 weeks ago when I finished building my exhaust. Sounds so sent when the turbo whistles.

Mine was straight piped for about 7-8 months and it sounded amazing. It popped and backfired and it was great...Until I found a cop who didn't like it. So I had to put a muffler on and it's super quiet when compared to straight piped. It still sounds good, it just doesn't pop when I downshift or backfire when I shift at over 5500 RPM.

I love the pops!
