Just the right amount of growl for a great price!!! 3 months ago
5out of 5stars

I installed this cat-back yesterday in a couple hours using a single 3-ton floor jack. The actual install took about 30 minutes, and 1.5 hours was spent fighting the old rusty exhaust fasteners. I guess that is what I get after seven New England winters. It fit up perfectly to my catted Invidia down-pipe. I would prefer it didn't have a slip-joint in the mid pipe. I just cranked on the collar, and it does not appear to be leaking though. I would recommend installing new hangers at the time of install. Mine were pretty worn out, and are not doing any favors for maintaining good alignment of the tips. The sound is exactly what I was looking for. Louder, but no obnoxious. There is a noticeable lower growl further down in the rev range, and a nice popping sound on throttle let-off. I don't notice much of a dB increase under hard acceleration (WOT) vs moderate acceleration. Which is surprising to me, but I only really have previous experience with aftermarket exhausts on motorcycles. I picked it up with the blackfriday deal, and with that it was half the price of other quality 3" 304SS cat-back systems. The price really cant be beat, and the quality is much better than I expected given the bargain price.

Great for the Price 2 years ago
4out of 5stars

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 2 years ago
5out of 5stars

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!

Great Quality Exhaust 2 years ago
5out of 5stars

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.

If you want a full 3" quiet system for a great price, look no more 3 years ago
5out of 5stars

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..
