Flowmasters sound good, there are also dynomax and thrush exhaust that sound good and arent as pricey. dual rear exit flowmaster super 44 series arfe the ****!

 

x2 on the duals lol

 

i have a thrush welded muffler and 3 piping from the cat back and it sounds amazing if you live i washington go to pro exhaust in auburn there not lieing about the pro

 

I going flowmaster 44 with duels on the blazer...2 weeks till there on... Ill post pics and a video when they are done. Ill even get install pics!

 

I believe it has been decided the only real thing you get from aftermarket exhaust is a new note on the pipe. Unless you install a better intake, exhaust, headers, and reprogram the computer (pref. with a chip controller), etc....

Don't get me wrong, do it do it!! Just FYI

 

I think you may get like 10 hp with a high flow cat installed to but even if it doesnt give me a hp gain im still doing it

 

I had flowmaster not bad but win I had to replace it I did with a summit racing muffler it was only $30.00 & I love it had it 2 years now with no problem's. in my opinion sounds better than the flowmaster. I have people ask me all the time if it's a V8

 

Only if you're going down a mountain with a stiff tailwind.
10HP is a big gain and requires quite a bit of engine work and $$$.

 

AND, if it did make 10hp everyone in here would have one on! I sure as hell would.

 

^ oh lol
