Hello! I have a 1998 Blazer Lt 4wd and I have an exhaust leak and instead of just "fixing" the leak I would like to do a complete replacement with either magnaflow or flowmaster I was curious of what your guys input was on both of these in your opinion which sounds better? which one will help with mpg? Any input is appreciated thanks again!

 

you can listen to them on their websites, use headphones. personal preference. I have dynomax but like flowmaster also

 

The GEARS tv show with Stacy David was working on a 1973 Plymouth Sebring project and was looking at the exhaust system for it. He was going to use a Heartthrob exhaust with Turbo mufflers. He liked the Turbo mufflers because they were quiet at low RPM but got more aggressive at higher RPM. What you should want to avoid is the dreaded DRONE at highway speed. Stacy then says he will install two electric cut outs for off road or racing applications.
I went to the Heart Throb site and they have complete cat- back systems for the S-10 pick up but not the Blazer!? However you maybe able to get just the Turbo mufflers.
I know you were looking for a complete cat back system.

 

I have a Roush Racing muffler from a 2014 mustang gt axle back system on mine dumped before the rear end. i love the way it sounds.. very throaty like a v8 at lower RPMS and just ***** to the wall like a formula 1 at high RPMS!!
