MAC vs. Flowmaster

Post by RTW0223 on Thu Jun 24, 2010 1:58 am

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 Smile )

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

By "stock catback", you mean the pipes from the H pipe to the muffler are stock? To gain more sound, yes, you need to step up from the 2.25". 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

as far as mac vs flowmaster, honeslty those two manufactures are all that i would ever run. they offer a nice old school sound imo 302 cant sound anybetter with mac long tubes x pipe and 40 series dumped, or if you prefer tail pipes thats good too. as for the catback/weld in muffler, ive ran flows for a few years no complaiints sound great

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.

Good sound is subjective. Something other than "old school" isnt bad just because it's different or newer. There is more to exhaust than just "old school sound", some of us want something that sounds good and flows better than MAC and Flowmaster. MAC products have always been junk, IMO. Cheap prices for cheap quality.

Prices? Of course an entire stainless steel catback is going to cost more than aluminized steel. Better materials, better crafstmanship cost more money.

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.

maybe this is the whole reason my junk/ride N/A has a hard time running low 14's/high 13's on the motor and needs help from my secret to get down the 1320 quicker, hrmmmmmm guess if I removed my MAC exhaust, I could pick up some ponies?? Bassani ehh?? wonder if that'd help me?? pirat

yup, full length headers 1 5/8's 2 1/2 x-pipe 2 1/2 mac cat back, it's not terribly loud but more so a high pitch scream when you get on it and it has some drone to it but my 89 is far louder and it has a flowmaster catback and is a bit slower than my 85

Dunno, maybe you should ask someone with a fast car what they think! I believe i may need to look into acquiring a secret like yours, because i want to go faster too.

yea but it aint gonna sound that much different i had a 2.25 inch and 2.5 with original 40 series about 4 years ago didnt sound much different to me at all. you can also buy 2.5 inch tailpipes from latemodel resto. a lot of companies mac, flowmaster, magnaflow make stainless 2.5 inch tails. just bolt it onto your 40 series mufflers if you want but its not gonna sound much different especially since you want it LOUDER with some tone.

AHH but your current secret is much better than mine as for faster, why you wanna do that?? you're already faster then me. I mean you run 13's and I'm still in the world of the 14's ....once I saw you run solid 13's today, this was me after I left

Just an aside from the "Peanut Gallery"....I have equal length BBK shorties, Pypes X pipe into 2 chamber Flowmaster 40's. Has a nice deep idle and when I open it up you can hear me from a distance. Nice, deep sound. Again, as posted earlier...its a subjective thing for sure! Good luck.
