Upgrade your Ride with the PILOT PM551 Stainless Steel Round Resonated Exhaust Tip Review

This exhaust system is a must-have for any automotive enthusiast. The stainless steel construction ensures durability while the resonator provides an impressive sound. Installation was easy and the result is a noticeable increase in horsepower. The only downside is that it may not be street-legal in some states. Overall, the Pilot PM551 is a great upgrade for any car.

They are advertised as 4" on Revain and elsewhere but actually have a 3.5" outlet diameter. They are simply longer 8" versions of the other 3.5" springs Pilot offers and are not larger in diameter. The packaging even says 3.5 inches. Although they are fine. Good quality. I'll probably leave it at that, but I really wanted 4 inches. I've looked everywhere for an affordable 4 inch tip and thought I had it with this one. I was wrong.

Like it, I had a lot of trouble installing it on my V6 rod because my exhaust pipe was very long and angled and I didn't have a proper tool but it looks very sharp and it seems that it will be quite durable. The only reason I gave it 4 stars out of 5 is that despite the resonance, the sound doesn't seem to make a difference, but that's what I expected. All in all I would recommend it to a friend. Good price and looks pretty bad***
