I've been running a catless DP and stock catback for quite a while now. Starting to get some exhaust leaks around the muffler and generally sounds shitty. I'm not really wanting something loud and droning. Compared to the K04, the ZFR and other turbo's have larger turbines and the turbine blades are usually not spaced closely together and lets a bit more sound through, so bigger turbos usually make the exhaust a bit louder which i noticed when i did the swap.

I do have an E-cutout on the DP for when i want loud. But I'm looking for a catback that has a deep and mild tone. Anyone with larger turbos, catless DP, what are you running and how is the sound?

I've been leaning towards the MPX 3" catback or the Hahn which is about $100 for what looks like the same thing, and Modern Performance is only 20 min. from my place.

I'm running zfr with zzp catless and stock exhaust. First thing I noticed after zfr is not louder but deeper note. Especially at cat warmup mode, stopped sounding like a dirt bike and sounded liked a performance car lol

I just checked out the turbo xs GT series for our cars, and thats what im going for, kinda quiet but deep and clean for the right price. The stock catback is getting louder every week lol. BTW, why still running cat warmup if using a catless dp?

I was running Catless downpipe and stock exhaust and it sounded like ****. but my car has 97k miles.

I recently got a custom exhaust made. 3 in catback with 1 resonator and no muffler. Basically TurboXS RFL but for half the price. It sounds awesome.

I agree it definitely sounds like **** with the stock catback, even though its nice nobody expects it to be fast bc its so quiet. I had the stock resonator and i put my old muffler delete back on and it was wwwaaaayyyyy too loud, put the stock muffler back on same day.

^^ My exhaust setup is pretty similar to yours. I'm running a catless dp, full 3" catback with a small resonator in place as my muffler. The setup sounds **** with the 6758 for sure.

Edit: Oops, I meant to point at leemafor.. lol

Mpx3" exhaust sounds great and it's only loud when you give it lots of throttle.

eh still too loud and not quite deep enough for what I'm looking for. I'll probably try the MPX full 3" with the resonator and muffler just bc its decent and the shop is only 20 minutes from me. Would love to hear a ZFR with the MPX 3".
