That's very enticing. Can you answer my other questions though: is the muffler packed or baffled, and what grade(s) of steel is the system made from?

I'd love to hear a sound clip with a catless setup and ace header.

This exhaust intrigues me now that I'm boosted. My only real concern is actually the tips. They are so large, they seem too close to the bumper and I worry about deformation over time.

What is the pipe size where the tips connect to the muffler? Do you think swapping the tips for something like these DC sports tips is feasible/will fit dimensionally well? https://www.amazon.com/DC-EX-1013-St.../dp/B003D4KA32

How much does it weigh vs stock?

Muffler packed & baffled. Currently we have put 6 months on our boosted car and the muffler has not degraded despite some hard runs. The catback is SS409 (edited). We have secret sound clips that have terrible video quality but good sound from our testing, however, we'd like to get better videos out there in better conditions for better sound capture.

The tips don't touch the bumper and you can adjust the tip exits a bit farther out so the exhaust gases don't wrap into the bumper. Our exhaust setup has seen about 6 months of boosted life without degradation of the exhaust and any issues with the bumper. :)

Whenever our guys stop getting distracted with other projects, it will be accurately weighed. :paddle:

Quick short video. Enjoy!

awesome. any chance you can make a clip of just the csgxmxp exhaust with stock engine or with just jackson sc? i only have the jackson so really want to get an idea of what mine would sound like since i don't intend to do headers... :thanks:

On both OP's car and the white one in the video it looks like the exhaust tip on the drivers side is off center from the cutout in the bumper.

@CounterSpace Garage Any info on the resonator and muffler design?

It was posted above.

Don't worry, you can't never lose with HKS man. I'm pretty sure HKS is probably better sounding? :cheers:


I think most of us oldies are trying to look for a more quiet but still nice sound exhaust without the drones....... I just really wanna drive to cali without getting a headache if my radio isn't on 50% + or full blast. LOL....

Thanks, I read that, but I was looking for more than "packed and baffled." And to point out that they have not discussed resonator design. Is it perforated or louvered core? What is the resonator packed with? Rock wool, roving fiber glass? Etc. What is the baffle design, etc. There is a ton of info left out. As with most exhaust manufacturers...

I haven't installed it yet, but I agree about the noise and drone. I have the Q300 but it doesn't sound all that great with the nameless headers and front pipe. Also the hks seems pretty nice from the videos of their header and front pipe with the cat back.

Correction, SS409. Got mixed with the MXP SP exhaust.

Have not. We had 3 cars to take quick clips on and they all had a different configuration with the ACE A-350 header.

2017 BRZ - ACE A-350 / ACE FP / Stock Exhaust
Customer - ACE A-350 / ACE FP / CSG Exhaust
CSG BRZ - JRSC SC / JR HBP / ACE A-350 / ACE FP / CSG Exhaust

The header + front pipe increase sound production due to additional flow and less "resonators" in the system. It will be quieter on a stock FP and/or stock header. Thank you!
