Hyundai i30 N Sedan (CN7) Stainless Steel Downpipe with High-Flow Race Cat - ESHY34KITB
Unlock the true potential of your Hyundai i30 N Sedan (CN7) with the Xforce Downpipe. This performance-driven upgrade is meticulously crafted to deliver optimal exhaust flow and significant power gains. The system features a massive 4" dump pipe with a precision-cast top to minimize turbulence right at the turbo exit, paired with a 200-cell high-flow metallic race catalytic converter for maximum efficiency.
Constructed from high-quality non-polished stainless steel, the Xforce Downpipe is built to withstand the rigors of intense track days and spirited driving. The 4" design reduces to a 3" outlet, allowing it to seamlessly bolt to your factory standard cat-back system or an Xforce Performance exhaust system. Experience a boost in horsepower, torque, and turbo response while enhancing the aggressive acoustics of the 2.0L Turbo engine.
Note: An engine ECU tune is required after fitment to ensure optimal performance and to prevent a Check Engine Light (CEL) due to the high-flow nature of the catalytic converter.
Features:
- 4" Cast Top Dump Pipe: Precision-cast inlet for smooth exhaust gas transition and improved flow.
- 200-Cell High-Flow Race Cat: Metallic substrate catalyst reduces backpressure while maintaining flow.
- Non-Polished Stainless Steel: Industrial-grade durability and heat resistance for high-performance use.
- 3" Outlet: Tapers to 3" to provide compatibility with factory or aftermarket cat-back systems.
- Direct Bolt-On: Engineered for a precise fit on the CN7 Sedan N chassis.

Best wire on Amazon
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
I am convinced that this is some of the best wire on Amazon, if not in general. It's much thicker with more strands inside than other wire labelled as the same AWG. It has much higher quality insulation that can withstand double the temps of the cheaper stuff (big deal if using in engine bay etc.). And even then somehow its supper supple and soft to work with, strips very easily and cleanly. Definitely recommend spending the extra $ to go with BNTECHGO brand for wire. I was very please with both the 12 and 14 AWG wire in 10ft red and black.

Flexible, soft, and full of wire.
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
Super-soft and flexible casing with a high density of fine wires inside. You won't have to worry about it being 90% insulation.

Very good audio receiver for my tower speakers and record player set up
Style: Stereo Receiver, Configuration: Receiver
I have had my 1980s Roger sound lab CG 82 Tower speakers connected to a 1999 Technics audio receiver. I use this set up for Radio and my record player.
After many good years, the low end on my audio receiver gave out. I have had it serviced before, but I have owned it for five years and it is a 27-year-old piece of gear that has seen better days. ChatGPT led me to this receiver.
It took me less than five minutes to connect my speakers. What I love about this receiver is that it’s so simple to use. The radio signal is very good right out the box without an additional antenna. I was resistant to buying a Bluetooth receiver, but it connected to my iPad and my iPhone in seconds. Now I can play backing tracks through my Roger sound lab speaker speakers while I jam out on guitar.
No issues with sound quality or anything like that. Runs cool and quiet. If you are a total audio file, you could buy something more expensive. I am a musician and I listen to vinyl. Mostly jazz and classical, and this is fine for my needs. For most people running a record player, looking to modernize with a Bluetooth enabled receiver, this will suit your needs.

LOVE IT - Great Performance and Great Price
Style: Stereo Receiver, Configuration: Receiver, Style: Stereo Receiver, Configuration: Receiver
Speaking as a self-described "audiophile" (but a true audiophile with deep pockets would likely laugh), this was one of the best gifts I've given to myself in recent years (as I have a fairly large music library of nearly 600 albums of 1/3 vinyl, 2/3 CDs and some cassettes).
Bought mine back in March--used to be $200, but when I saw it for $150 any hesitation went out the window and I grabbed it. I have been in love with it ever since. Fabulous sound and power (do you really need more than 100 watts per channel?), great remote control (not used to that, believe it or not), and it lives up to Sony quality. Powers my vintage components perfectly:
> MCS Series 6202 Belt-Driven Turntable (had it since early 80s)
> Nacamichi BX-300 Cassette Deck
> Sony DVP-NS725P Disc Player (DVD but used mainly for CDs - audio-only connection)
> LG TV connected via optical-to-analog adapter
> KEF Reference Series 103/3 Stereo Speakers
Interesting observation about the way the ports are labeled on the back: what would traditionally be identified as a tape deck port (with IN/OUT) is just "Input 4," and while it's connected to my tape deck for playback, the REC-OUT is connected to a USB audio adapter to digitally record anything (mostly vinyl of course) to my laptop for mastering and iPod/digital library access.
The Bluetooth connectivity is awesome as well with powerful range - great for playing music from mobile devices (phone and iPod Classic with BT adapter). The front line-in 3.5 port, identified as a "Portable" is also a great feature.
At first, I was surprised that there was no input for optical, however since digital-to analog adapters are inexpensive and readily available, I think it's best to leave it that way. Would rather have the option, rather than an optical-only port that would otherwise go unused unless one had a component that required it.
HOWEVER, if I were to make any improvements, it would be to add a USB Out port (preferably on the front), for digital recording on a PC. However again, since adapters are inexpensive and accessible, and for the price I paid for this device, I ain't gonna complain. Front level analog balance, bass and treble controls would also be nice, but you have access to all that through the menu.
If you feel due for a simple, powerful and awesome stereo receiver/amplifier upgrade without breaking your monthly budget, this is a winner.
