Get loud pipes for 01' COBRA!

"System arrived very timely and was pretty easy to self install. Just make sure that you measure everything before making everything tight. One tail pipe stuck out farther than the other but an adjustment quickly fixed that. I love Flowmaster mufflers and they are the only performance mufflers that I buy. My 05' F-150 has them and my previous COBRA had them too. Looks great and sounds better. This is not the kit to buy if you want to sneak up on people. You WILL be heard and I love that!!!"

"The Flowmaster sounds great! Also had a cold air intake installed and now I'm getting 23 MPG. They should pay for themselves in 40,000 miles, sounding good the whole way. Wasn't interested in any power gain only MPG and got what I wanted."

"The sound of the 5.7L Hemi was incredible. I got the dual rear exit exhaust and just the look of the exhaust system from the back of the truck made it look fast. The quality of the exhaust system is exceptional. I do suggest however, that owners tack-weld the exhaust pipes. Horsepower gain was noticeable as was fuel mileage (if you drive it conservatively). Overall, I'm very impressed with the quality and performsnce of my Flowmaster American Thunder exhaust system."
