My take on Gibson is that they are junk... I bought a SS exhaust for my truck that rotted off... Since it rotted at the seams it was not covered by the lifetime warranty.

Flowmaster is "junk" that isnt even stainless steel....


But you'll be hard pressed to find another system that sounds as good as some original 40series flows do on a 5.0 with long tubes. Regardless of how popular they are and how bad they drone, the things are not quality mufflers, but they sound good from the outside.

I don't understand the comment on flowmasters. I have never never never had a set go bad or rust out on me. The one off my z28 was bought in 1996 and came off because of an improper cat converter weld by a local shop->dragging the whole system down the hwy at 75mph. The muffler was tough and I kept it on the car until I sold it. I sold the muffler to a friend who put it on his chevy truck and left it on until one year ago only because he wanted a different sound! That is 11 years.

I since then have bought delta flow and they were also ROCK SOLID. I have had flows on other cars too and never once had an issue and quality was excellent.

My personal opinion of flow's isnt that they dont last....but read reviews on them. The general consensus of them is they arent a quality muffler and they dont perform well (although unless you are in a turbo/super charged car....the muffler doesnt matter n/a IMO).....go do some searches for flows....people will rag on them for being bad. My only point was that i dont care if a muffler is going to fall apart or doesnt flow the best, if it sounds great thats all i care about. Cause even flow's which people say are bad quality have been great for me.

Oh. Yes they have not flowed the greatest. I know what you mean. NA most peeps dont realize is prolly a 7rwhp max between mufflers but like you say for PA I wouldn't go flows.

Actually its less than 7rwhp even....

MUFFLER SHOOTOUT:

Results based on 5.0 Mustang Magazine December 2002 issue (page 55). Test car is a ’90 Coupe with 370 HP and 11 second potential. A number of 66 pulls were made to compile this information. Where does your muffler stack up?

The results in HP order:

1.Flowtech Warlock (open) 374.2 hp/ 333.1 tq
2.Bassani Real Street 373.7 hp/ 333.8 tq
3.Hooker Maxflow 373.5 hp/ 333 tq
4.Borla XS 373.3 hp/ 332.6 tq
5.Magnaflow 372.8 / 332.5 tq
6.MAC 372.3 hp / 331.5 tq
7.Flowtech Afterburner 372.3 hp/ 330.1 tq
8.Hooker Aerochamber 372.1 hp/ 330.4 tq
9.Bassani 372 hp/ 333.5 tq
10.Spintech 371.6 hp/ 332.2 tq
11.Edelbrock Performer RPM 370.9 hp / 331.3 tq
12.Borla XR1 370 hp/ 334 tq
13.Flowtech Terminator 369.5 hp / 331.3 tq
14.Dynomax Ultra Flo 369.4 / 333.2 tq
15.Flowmaster 369.4 hp / 331.8 tq
16.Flowtech Warlock 366.3 hp / 325.3 tq
17.No muffs 365.2 hp / 330.1 tq


The quality of air can change those numbers more than a simple muffler swap on N/A cars. Now turbo cars.....completely different story.
