    • Didn't fit... not amazon's fault...
Nope, this older vehicle had two models, bade and high performance. They do not make the base model any longer, i have determined through research. I did find the correct unit though, through measurements.

I don’t think I’ve ever done anything so easy as this. Cut off the muffler with a sawzaw old pipe fit perfectly into the muffler and used a clamp I bought separately. Could not recommend more. It’s really quite too.

    • Good quality but by the time I cut off original ...
Good quality but by the time I cut off original from exhaust (cut exhaust off RIGHT AT muffler), I came up short (maybe 1.5 inches) chose to weld extensions onto muffler hangers for a better fit. Not really necessary, but less stress on hangers and not "pulling" on them. Other than that, inlet was a good, snug fit and clamped down well to original exhaust. ... show more

    • Excellent fit, sounds good.
I used a metal blade in my Ryobi cordless reciprocating saw and cut the existing exhaust pipe as close to the old muffler as possible. Without removing the passenger-side rear wheel it was challenging to cut the top of the exhaust pipe so I ended up cutting all but 1/4" to 1/2", slipped the muffler out of the two rubber isolators on the tailpipe end then "rotated" the muffler a few times to cause the remaining bit of metal to snap. The new muffler's hangers fit nicely into the rubber isolators and the old exhaust pipe slipped into the new muffler with ease. I slid the recommended u-bolt clamp over the mufflers inlet ensuring that the old exhaust pipe was well enough inside then used a deep 1/2" (?) socket to tighten the nuts. It was immediately obvious that the old muffler was long overdue to be replaced. The new one was a direct fit, overall installation time was less than 30 minutes from driving the car up onto ramps, removing the old muffler and down the street for a test drive. My wife commented how she can now hear the wind noise while driving instead of the rumble of the exhaust, I guess I am replacing door seals next. ... show more

    • Easy Install
This muffler fit perfectly on my 2008 Impala. I cut the old pipe as close to the muffler as possible with a grinder and sawzall. The new one slid over the old pipe. I used a muffler clamp that I purchased separately. The whole job took about 45 minutes. I took the rear tire off for easier access.
