I just had the Rae dual exhaust with mufflers and a resonator installed, and the difference it makes is incredible. Compared to the Invidia R400 I was running before; this setup is on a whole other level. The sound is deeper, smoother, and far more enjoyable without being over the top.

What really surprised me is how little drone there is. Even at cruising speeds on the highway, it stays quiet and comfortable inside the car. But the moment you press the gas, it delivers a bold, throaty growl that really wakes the car up. It’s the best of both worlds—refined when you want it, aggressive when you need it.

The quality of the system is top-notch as well. The parts fit perfectly, the finish looked great, and installation was straightforward. It feels like a premium product from start to finish.

I also want to give a huge shout-out to Melanie. She made the whole buying process simple and stress-free, answering all my questions and helping me choose the right setup. Thanks to her, shopping for this exhaust was just as good an experience as driving with it installed.

Highlights:
• Deep, clean tone that’s better than the R400
• Practically no drone during normal driving
• Aggressive exhaust note when accelerating
• Excellent fitment and build quality
• Amazing customer service—thank you, Melanie!

Overall:
The Rae dual exhaust with mufflers and a resonator is absolutely worth it. It delivers a perfect mix of performance sound and daily drivability. I couldn’t be happier with the choice, and I highly recommend it to anyone considering an upgrade.

Working with FelixPerformance was great. Highly recommend them.

The fitment for this setup was great for my 2024 WRX limited. Only caveats were that you might want to run to auto parts store just for heavier duty bolts because the ones that came with kit were kinda weak. I got a free bag of garbage pale kids too in the bag of nuts! Thank you! One thing, just in case you have second thoughts on say for instance just putting the downpipe in and not the j-pipe, the downpipe obviously will not fit with the stock converter so if your going to do the whole shabang, do the whole job. My back hurt thats why I was going to do that but Im glad I installed the whole kit including j-pipe. One last thing that's mucho mucho importante! Make sure you pre-soak your hot side turbo nuts/studs on stock j-pipe with PB Blaster or WD40 AT LEAST 24 hours before you try to take them off. At least have a little propane torch on hand as well. Final thing, last thing I swear.... Make sure you also purchase a 14mm nut extractor either at Harbor Freight or Amazon, it will save your life.
The sound is real crisp and throaty, a real growler and it bolted right up to my MBRP cat back exhaust..

Thanks. Fast shipping. Easy installation and super great quality paired amazingly well with my COBB SS catback! Thanks!

Installed it 6 months ago while doing head studs.
Easy to install spools instantly.
Has plenty of top end too!
Paired with a dman tune this turbo is the best stock location turbo on the market

Best intercooler in the market, thanks to Melanie for facilitating this transaction always making it easy.

Amazing tune. Amazing customer service. Dmann is an artist.

I've been running the OTS 93 for about two weeks. I don't tend to push the car hard hardly ever. That said, the 2500-3500rpm range feels so much better on every gear. Shifting between 1-2 and 2-3 is much smoother. I did go down 1mpg over the 200 miles so far on avg ...but it feels so much better I do not care at all. I waited a year before turning, I wish it was always like this. Hopefully it'll serve me for years to come.

Quick shipping

Insanely happy with this order, quick. And service was great. I live near the shop, definitely gonna have to stop by to check it out.

Super easy install, definitely increases noise when the turbo starts to build boost. It doesn’t really increase the blow off (as expected) and looks great

This is the best bang for your buck! I cant glorify this purchase enough. This package made my car a thousand times better. Anthony from DMann tuning made this the best e-tune experience for a first timer. If you like your wrx and want to smile from ear to ear every time you drive it, then get this package. I got the ETS intake and the quality is top tier. Once I get more mods I’m definitely going to Anthony for a dyno tune. He’s out of state for me but his experience makes it worth it. He has my car running perfect!

Completely transformed my car. Have driven 1000km so far with the 91 OTS map with AEM intake. So far so good no DAM drops. This is how the car should be from the factory! The torque curve is so flat and this tune is so addicting. MUST HAVE FOR ANY VB WRX!

I was looking for a performance J-pipe assembly so I reached out to my e-tuner, Dmann, and he referred me to Felix. After making contact Melanie replied to my email and got me on the right track. I was looking for a J-pipe for my '21 Legacy XT. She thought it might fit but it wasn't 100% certain. I also read somewhere on the site that the intermediate pipe needed wouldn't fit to a Nameless catback. I rolled the dice and ordered the J and the I pipes. I measured the lengths when it arrived and it looked pretty close so I began the teardown. A quick note on that...the turbo studs (x3) were real B's to get loose. I highly recommend dousing that whole assembly in Kroil and then more Kroil and let it sit overnight. You'll thank me later.
Once the OEM J was off it was easy work from there! I did have to run out to get a new Walker Exhaust Pipe Flange Gasket (part # 31657 at Advance Auto) to join the I pipe to my Nameless midpipe but it fit even better than it did when my catback linked to the OEM I pipe.
My Nameless muffler delete was growly before but it's a banshee past 3000 rpm now.

These headers absolutely make my WRX sound so good! I never listen to music anymore all I do is listen to my engine super satisfied with this purchase.
