Magnaflow Vs. Borla

[00Z28DC]

hey guys, i'm new to the forum and this is my 1st post. I've got a 00 Z28 (A4) and i'm planning on gettin a cat-back exhaust soon, but of course i don't have a crapload of money to spend, so i've narrowed my decision to magnaflows new quadtip exhaust and borla's quadtip, i just want to know which one will be better in terms of torque and hp improvement as well as sound gratification : ) ?

[LS1formulafreak]

cant go wrong with either, but i would lean towards borla imo, but i really have nothing to back that up with, sorry...

but i know some of these guys do, GOOD LUCK

for the price the magnaflow is a very good system, stainless steel and mandrel bent

slp loudmouth FTW!!!!!!!!!!!!!

I have borla on mine and there is someone in my car club with similar car and Magnaflow. Personally i like the borla. The other car's owner said that magnaflow wasnt much different than stock(ws6 exh.). I dont mind the sound of the magnaflow but like the borla sound much better.

[sgt0704]

price wise, you'd be better off with Magnaflow. you can even find people selling theirs on the boards for cheap.

and there's a thread on ls1tech where there were numbers posted from a dyno'd mustang. and the differences between the cat backs were litterally 3-5 hp and 3-5 tq. and for the extra 300-400 bucks for a borla, for the 5 hp gain isn't worth it. and those higher numbers
(4-5) range, were flowmaster.

[Wesman]

I would go with the Magnaflow system. I've heard it on a couple different cars, and it sounds great both with stock manifolds/cats as well as long tube headers. Its also much more cost effective than the Borla, and its stainless steel I believe, too.

hope this helps.

The magnaflow here is all 3" so im assuming it flows better than what this says...

[Mr. Luos]

slp loudmouth FTW!!!!!!!!!!!!!

I had to cut mine off it sounded SO bad with longtubes.


Magnaflow is my choice from now on.

[rel3rd]

Had a Borla adjustable setup...Originally with stock manifolds, cats and stock Y pipe.

Swapped on longtubes and ORY.

Absolutely hated the gurgle sound when accelerating, sounded like it was going lots faster than it was...soon afterwards I sold it.

Swapped back on the stock catback, which actually sounds pretty good with the longtubes.

Have a Magnaflow setup coming...

[00Z28DC]

hey thanks for the help, i think i've decided on the magnaflow quadtip catback system. according to magnaflow, it gives a 17.7 ft-lbs of torque and 13.8 horses and it's gonna cost way less than the borla system. So thanks again for all the help everyones been.

Dont forget, his flow chart is for a mustang with 2 2 1/2" pipes.

The quad tip is pretty expensive from summit. Almost as much as borla from what i saw.

[JwMonE99]

In my carclub, we get sponderships from borla, being one of the few muscle cars in there borla is pretty much a must for me, plus its FREE lol cant argue with that

Dude you told me you had a v6 with a blown head gasket. Did you buy another car?

[LETHALxLS1]

I hated the way the loudmouth sounded too. I took the resonator off and put a Borla xr1 on. Sounds great now.

[Pitchlock]

Why 300 bucks more for the quad tip magnaflows. Nothing different in performance. Just looks like different tips. They do look nicer but not 300 bucks nicer.
