MAC vs. Flowmaster

looking for a new catback

Right now I have MAC 1-5/8" Long Tubes with MAC 2.5" off road H pipe to the stock catback with 2.25" Flowmaster original 40's welded in (courtesy of Mike )

My car is extremely quiet at idle and barely opens up. As i accelerate normally the sound is odd... you can deffinately hear the 40s, yet it sounds as if the exhaust can hardly 'breathe', if you know what i mean. Also, there is almost no interior sound..which is what im looking for. I was told the quiet exhaust is due to the small piping of the catback.

So what should i save up for...

the American Thunder catback 2.5" piping with 2.5" tips with super 44 mufflers

OR

the MAC flowpath catback 2.5" piping with 3.5" tips

I was told the MAC flowpaths out perform the Flowmasters. I know that asking what is the 'best' set up is kinda vague, but with my setup (long tubes and o/r h) what will give me the louder and more badass sound


ugh lol

It's been years and years since my Fox body days, but I do know that a larger diameter muffler tip does help produce a deeper tone, but as far which is better, MAC or Flow...??? I tried that out once on my LX...it had the American Thunder kit on it and I took large wax/paper cups, cut an "X" in the bottom of each one, so that it would slip over the pipe and provide a somewhat tight fit. The cup lip was a larger diameter than the pipe tip and it did make for a deeper idle. The reason I did this was, I was thinking of having 3" tips welded on, but somebody else had plans for the car before I ever got the chance... The larger diameter pipe and muffler tip will increase both inside and outside sound

yea by stock i mean my whole catback is 2.25. i know i need to step up to a larger pipe, but now im stuck between mac or flowmaster. ive heard mixed reviews

hmmm airbox? what do you mean

bassani slp magnaflow on these cars to me just dont belong on them the modular v8's in the later years really sound good with them but not the 5.0, and the prices of the cat back???.... you could have your entire exhaust system paid for for the price of one of their catbacks. i have 300 bucks in bbk shorties o/r H pipe and dumped flows.

i agree with the fact that flowmaster and mac are great for the foxes. like if i realy wanted to just have the loudest and most obnoxious car then i would go to SLPs no offense to people who have them i mean they sound awesome had them on my v6 and it was loud but now that i have the 5.0 i dont want only LOUD but GOOD sounding too. And another reason i am probably going with MAC is just because everyone and their moither has flowmasters on their fox.

idk if thatd give you any more hp but this ride of urs has MAC ?
