Questions & Answers Ask a Product Question

if these are stainless steel can they be welded to standard metal piping

Asked by MATTHEW on July 09, 2019

You can stick stainless to mild, but a true weld? No

If youknew a good TIG welder, maybe.

But the high Chrome content doesnt work well withmild steel.

Use an exhaust clamp.

I tacked mine into place, and clamped it.

JOSH from NJ answered on July 13, 2019

Yes. If you want it to weld better, cut a piece of pipe about 1" long. Cut a gap in it and grind it so it fits inside the joint as a backing. The goal is to stop the back of the weld from being directly exposed to open air. Normally, an argon back-purge is ideal, but that's for sanitary/structural/high-end stuff, not a bargain $50 exhaust.

-This is a 409 stainless product, which is a low-grade of stainless steel. 11% chromium. The chromium is what makes stainless steel less likely to rust in humid areas.

- Higher grades of stainless like 304 can develop "sugaring" when welded without a backing or argon purge. 304 stainless can have almost twice as much chromium and up to 20 times as much nickel. Totally different material.

Yes

WENDELL from NC answered on July 13, 2019

The short snser Yes you can most definitely weld Stainless Steel to mild steel however if you just use mild steel filler wire or rod such as a 70s it will contaminate the base metal and lower it's resistance to corrosion and the structural integrity of the weld may be questionable as well without knowing the metallurgy and weld procedures for joining the 2 disimilar metals because Stainless comes in many different grades plus you have 4 different types of Stainless steels Ferritic,Austenitic,Martensitic,and Duplex so the variables are almost endless generally in order to weld 304 stainless to mild steel you would use 309 filler metal. Good Luck !

is there a female and male end to these mufflers or are they both male? (For clamping).

Asked by JAMIE on September 06, 2019

Thank you for your question. Flowmaster 71416 muffler has two male ends that have an outside diameter of 2.5 in. This is a straight through flow design muffler and can be mounted in either direction.

Summit Racing Answer - September 11, 2019

Both ends are female. The mid pipe and tail pipe fit inside the muffler.

Customer from AZ answered on September 11, 2019

Do you have a muffler 20" overall lenght 2.5" with inlet female and outlet male?
Thanks
Chris

Also on my 2012 Jeep Grand Cherokee I’m running on 5.7l straight pipe 2.5” in with 4” out tips will this muffler make it a little quitter but still great sound?

Asked by JOHN on May 20, 2020

Quieter than the straight pipes for sure But still loud

Hi,

If I have a 2.5 exhaust pipe and if this muffler is 2.5 male, how can I connect them? They won't fit together. I need at least a female...

Asked by CHRISTOPHE on January 11, 2020

Awesome sound

Installed these on my ‘12 challenger. It has a real nice deep throaty sound getting on it. Real mellow on the highway when cruising.

Fresh out of the box they look like a well made muffler. Clean stainless. Nice welds. Big logo neatly stamped into the material. I put them on my 64 Impala with a 350 that had open headers and they made a noticable difference in noise level and tone. They are actually quieter than I expected. Gives the car a decent muscle car tone. Would totally buy and use again. ...read more
