2000 Blazer
 

Hey, I don't have a Blazer but my girlfriend does and she mentioned how she would like to have a an exhaust put on for her birthday. I know a good exhaust shop in my area to do it. Here's my question, how big is the exhaust piping on the Blazer since I'm going to get a Flowmaster 40 muffler for her? Also, will there be any problem with just cutting out the old piping and putting the new muffler in there or will a whole new setup need to be fabbed up?
Thanks for your help guys

naw, you can just swap the muffler. if a good muffler shop is doing it, then they will be able to make it fit with reducers.

But how big is the piping? 2.25"? 2.5"?

no clue. sorry. you could just crawl under and measure

Tell em how it turns out i think its 2 and a half inch

its 2.5 and flowmaster is not the best muffler. i say go with a ravin z55. its a bit louder and more free flowing. ive been asked if i have a v8 under the hood.

i got a 40 series put on mine, its 2.5 in and 2.5 out. i was gonna dual it out but the spare tire prevented that and yeah they used the same piping and i think they added a little. cost about 40 bucks. mine sounds good im happy.
