ok so in the time period of this year iv blown out the welds in 5 mufflers so far. flow master knock offs, real flow masters, and now my macs. any ideas how i can stop this? i dont wana have to buy new mufflers every 3 months or so

 

with a 3 inch drop you sure you're blowing them out and not scraping them apart by bottoming out when backing out of or pulling into driveways?

 

nah the casing on all the mufflers have been un touched the subframe connectors hit before the mufflers. if i hit the muffler with a screw driver i can hear the parts rattling

 

You sure it's not your cat falling apart?

 

points to Mac O/R H pipe in sig

 

Still wondering what springs you have for a 3 inch drop and how the hell you drive it lol.

 

ive had flows and flow knock offs on both my jeep and my mustang and ive never had a problem and the way i wheeled my jeep should have beat the hell out of them but ive never had a problem

 

I've never seen mufflers just fall apart, maybe the knock offs, but not a name brand unless your driving conditions are just brutal.

 

i chopped my springs and i drive it over nothing but smooth ground lol makes the center of gravity real nice though i have to actually have a friend lift my wheel well to get a jack under the car hahaha

and to Ryan i wouldn't exactly call my driving condition "brutal" but i like to have fun lol. however i have noticed a extreme amount of air moves through my pipes like at idle the air outa 1 of my pipes is the same as alot of peoples car and like 2500-3K rpms is it possible that i could be over flowing them? i don't think thats rly possible but i've been wrong before.

 

Well Flowmasters and many others will rust internally quite badly if there is a lot of moisture and exhaust has moisture in it.

We have a set of series 40's and there is almost no baffling left in them because it rusted out. I shake the muffler and chunks of rust come out.

Our Borla's are stainless and have never had that problem.

Maybe that is the problem that you have.
