Great for the Price
JJBTEXAS 10 months ago
I bought this exhaust to replace my previous aftermarket "fat can" style exhaust. The 2 reason I chose this, over other options were it's price and the fact that all the other reviews here claimed it was too quiet. I was looking for something that was full 3", but not obnoxious. I can happily report that this appears to fit the bill perfectly. Pros: Cost effective Low Rumble (Hz) Lower noise (Db) - from the perspective of aftermarket, still louder than stock Cons: Heavy Slip joint (would have gladly paid extra to avoid. Alignment not perfect

Great affordable exhaust
Mark 11 months ago
Installed this last week and I must say I'm pretty happy about it. Install took about 2 hours by myself only had issues with the bolt cause it wouldn't fit form catalytic to the mid pipe. Anyways, if you're looking for a little louder exhaust than stock this is your exhaust. Definitely deeper sound and it has that boxer rumble. Most definitely not going to be loud like Indvidia or Cobb but just enough to give it a little kick. Cabin sound is mild. Noticeable inside the cabin but not bad at all. Wish it was a little louder but it has great sound for sure. Great for daily drive. 5/5 stars. P.S. guys at rally sport direct are great with costumer service so if you have any question when installing give them a chat online!

I finally installed mine,its slightly louder than stock and that's really what i was planning for the longest time.just wondering if the tips sits lower from the bumper? Mine got about two fingers down.i thought that it will fill up the opening and stick out a lil bit more also using cusco hangers.I'll be posting a review and pics here in a few.

Great Quality Exhaust
jtporemba61458 2 years ago
Fitment is perfect and its very quiet. Absolutely no drone whatsoever. Overall quality seems to be excellent! Only gripe i had was the clamp that comes for the slip joint is terrible. Wouldn't seal it at all. Just get yourself a walker 33222 and it will seal perfectly, costs $8 and will save you a huge headache.

I got mine 2 weeks ago and x-force seems to updated to lap band exhaust clamp,unfortunately it got crushed during shipping so just waiting on the replacement part handled by RSD.

If you want a full 3" quiet system for a great price, look no more

Just installed this catback yesterday and it is QUIET! Even with the 3" catless downpipe on my car, it's slightly louder than stock. My car is a Daily Driver and got sick of the 4" muffler setup I had before and wanted something as quiet as possible while maintaining full 3" piping. Since I still have the perks of an external wastegate when needed, this seemed like like a great choice and I'm not disappointed! Definitely a bargain! Compared to other exhausts I've heard this is probably the most quiet 3" aftermarket system..

Great system for the money
Riley 2 years ago
I've been running the x-force turbo back and I'm very satisfied. I definitely is a little bit quiter than the Cobb or invidia. If you are looking for something that isn't way loud but just has enough sound louder than stock this is a great system. I would like it to be a little louder but overall it still has a great sound to it. I would highly recommend Especially for the money but if you are looking for a really loud system I would say the Cobb or invivdia would be better if that's all you're going for.
