VRSF 3.5" Catless Downpipe W/Stock Exhaust
- This is the way to go, and I couldn't be happier.Review by ryanakata
So I get everything back together, and the first start, CANFlap Open, and Whooaaaaaa it's loud. My parent's come outside to see if anything is wrong but then it idles down and sounds just fine. I take it for a drive and am in love with the sound. You can hear the turbo spooling in normal driving. I get the car warmed up, switch to Map2, head out near the airport. This thing is a beast now, I had to use the DTC button to prevent the car from interfering with the throttle. It slams you into the seat, and sounds like an exotic after 4k RPM. Combined with the JB4, this is the way to go, and I couldn't be happier.

- Quality product it fit first try!Review by ZeroSix
So cold start is loud. Once warmed up it goes to a quiet rumble a little louder than stock. Regular civilized driving there isn't much sound difference either. It's very nice for cruising. The smell is similar to a lawn mower it's not awful but for sure noticeable. Now when you push the car...music to my ears! It sounds amazing. You can hear everything from the intake pulling in air to the turbos spooling and the exhaust roaring behind you it's beautiful! I'm debating on keeping it how it is now! The turbo spools a lot quicker, response is improved. And my stock run flats don't hold traction (gotta change them ASAP) oh man those pops and crackles are crazy! I've scared a few people on the side walk.
I really have nothing negative to say about this Downpipe it was worth it entirely. Quality product it fit first try. I have a JB4 so it clears the code for me so I can't tell you how long it took my CEL to turn on. I'll try to upload some videos for you all! If you have any questions or whatever feel free to ask!

- Fitment was perfect!Review by Jgabucc1
I have read several reviews on this forum none of which really convinced me or drove me from an emotional standpoint to get this done due to issues with CEL light, and installation hassle of getting this installed on a XI.
To keep this brief and to the point, anyone who is on the fence about swapping out the stock downpipe DONT BE! This is of course your currently running a JB4 or other tune. The car should of came like this out of the factory. It's a whole new animal and has really added to the fun factor which simply wasn't there before. Acceleration in all gears and RPMs has increased tremendously, add that to the fact the sound of the turbo spooling, big increase in burble and pops heard, I almost want to say I look forward to getting in the car and going for a drive.
Fitment was perfect and the unit aligned, with a little play of the exhaust, perfectly. I'm very very happy with my choice and regret not having this done sooner. No idle issues to talk about. So far after two days I haven't smelled anything differently than when the catted pipe was on the car.
