Yes, people have them but they arent worth very much for the amount of work involved in the install. Less than 8hp. -Dan
Did you get a tune after the install? Last months 5.0 has a write up on the install and says you need a tune with them, I was thinking about a set myself.
I should also add... Forget about the supposed horsepower numbers, the real test is on the drag strip and many people would not waste their time and money to do it again if they could. They dont do a thing for full throttle evironments. If you are into bench and magazine racing these are for you. -Dan
How do they sound, that's more important to me than hp gains. I have heard they drone heavily on the highway.
i understand the first post was on mufflers however cleavlands responce was on the charge motion delete plates so i posted my opinion and results with them. erased it all at this point since its hijacking the muffler thread
I had the IMCO axle back on my car. The have two versions. I got the short ones. They were way too loud with my bassani x-pipe and had a horrible interior drone on the highway so I took them off and put my stock mufflers back on. They are now sitting in the shed collecting dust.
