I am too busy to read thru your 10 page thread although I'm sure there is some very good info there, so in short, did you have obnoxious drone and reduce it by a large amount by simply installing these insets?


Do the inserts come in different sizes?

Well, if you go to the Car Chemistry link, you'll notice the drop-down menu that shows what sizes are offered.   Shootself

And you actually replied back to him in the long-ass thread way back in Oct 2017, Geoff (after he'd installed them and reported his results).   whistling

To get back to the topic. The Torino is no trailer queen , in 8yrs it has made many 1-4 hr trips to cars shows. He put the magnaflow mufflers on a couple years ago . Cruising at 55-70 it is much better. I think it also picked some hp.

I'm old so i have an excuse not to remember that, plus my reply was probably too long for me to read now.

I am having engine rebuilt and headers put on, so I’m sure it’s going to be louder than before. I’ll let you guys know what I think after it’s done.

This is the answer I would like to know... hope the headers do work out well!

I have dynamax turbos with Hooker headers and 2.5" piping in a 4V and the sound is great. No issues at highway speeds.

 …. Well, I'm old too. Can't remember what I did 5 mins ago, let alone back in Oct 2017!!
 I'll look that up again.
Thanks young man!
Geoff.

 The Dynamax Turbos is what my local muffler specialist suggested. I think I'll look at those as an option.
I went back and re-read most of the 2017 thread. Most of what has been asked in this post is mentioned in that thread. However, I don't think the inserts are what I want to use.

Haha

I looked at the inserts, and they actually reminded me a little bit of SuperTrapp mufflers/exhaust tips - the more plates, the quieter the sound.  I'm not so sure I'd want to jam something like that into my pipes either.

Back to the Magnaflows: the exhaust shop I went to for welding in the O2 Sensor bung and some hangers, was pushing the Magnaflows pretty hard when I was there... I had to remind them that my exhaust system (including the mufflers) was 'only' 6 actual years old (less than 2 months old, if you go by actual mileage).  I guess when I finally get the windows and HVAC squared away and can actually drive with the windows up, I'll give it some consideration if there's a drone with the Pype Street-Pros that came with my exhaust system.
