Blazer Exhaust kits
 
Anyone used an aftermarket exhaust kit? I have the muffers so just need the pipe kit.

Heart Throb Exhaust makes a kit for 69-72 4WD Blazers. Part # 8141590. They list it for $441. If you search around you can typically get a better price from one of their distributers. Can buy with or without mufflers.
Good luck.

Thanks for the response, I checked out their kit and it looks user friendly.

I have used these on several builds. Not perfect, but still work well.

I used the stock exit 2.25" kit from LMC. No fitment issues. I installed it with the body off.

Thanks, I checked on it and looks to be a good option. LMC say "out of stock" for Blazer and Jimmy models.

Another vote for Heart Throb Exhaust - have used it on several blazers/jimmys w/o issue. As noted - it isn't perfect - but does the job if you have the OEM manifolds still.

Thanks guys, I’m leaning towards heartthrob if available.

By looking at these photos pulled from the Heartthrob site, the LMC kit installed on my 1970 K/5 looks identical to this. Heartthrob might be their supplier.

I used the heartthrob and my own Thrush Welded mufflers and am very happy. My only complaint would be the passenger side pipe runs really close to the transfercase. Edit:I used band clamps instead of the u-bolt style muffler clamps included in the kit.

I missed that they are offering these exhaust kits.

I ended up having to go to a shop & have a full system put in. I would have been more than happy to buy this system. I wonder if heartthrob would have been open to selling a partial system. I would have been more interested in a collector to muffler system where I either leave it dumped or have the tail pipes ran different.

Thank you posting this topic.

I have messaged heartthrob to see if I could buy just the tailpipes and never got a responce.:(

I went with the Hearthrob kit and I'm happy with installation, the kit is w/o mufflers I need to trim length of pipe to fit mufflers.

Thanks, the kit was very easy to install. I had to make a couple cuts for my mufflers to fit. I did this installation on my garage floor I would say that was the hardest part. I went with NAPA for my purchase.
