Excellent product, fit and quality are first rate. Great value, boss sounds and runs better!
Took us 2-3 hours to install with only a jack and jack stands. Had to get a pipe cutter, if you don't have it on a car lift, the original pipe is to long to get out in one piece! But other than that the Gen-2 over axle pipes are an awesome item. The car sounds deeper and a little louder without the original restrictive resonators. Plus you gain some extra power, along with knowing you have replaced lousy aluminized steel with high quality 304 stainless that will last a lifetime! Review by Jordan / (Posted on 3/25/2016)
Great quality component !
Installed on my 2011 GT with BBK Xpipe and Roush axle backs very easily.
Sounds very clean with no drone and a very nice growl at higher rpms.
Very impressed ! Review by Chris / (Posted on 10/17/2015)
Quality Product
I purchased these on a Friday and had them at my door the next Wednesday, for free shipping that aint bad. The pipes fit and sound great, I already have the lethal off road H and the GT500 axle back, so I can't comment on the product by itself, but for me it kept the sound mellow under 2500rpm but gave it a deeper tone, and the car really screams above 2500rpm now.

**A tip to anyone doing this on jack stands like I did, make sure the car is up as high as possible and that the real suspension isn't loaded (you don't have the rear axle jacked up, use the jacking points on the body) or else the stock pipes won't come out.

Thanks Lethal Performance for a quality aftermarket part! Review by John / (Posted on 7/17/2015)
Very nice Pipes
Ok lets say this, yes its a lot of money and yeah you can have a muffler shop maybe make these for half price, but let me say this these pipes are awesome, they have PLENTY of room for lowered cars, I am lowered 1.5 inches and not a problem, they sound amazing and just the adjustment on these are worth having them, installed them in about an hour and a half, on jack stands, very nice quality and sound..!
