Magnaflow ehaust

[Kevin427 18]

Hello everyone, I am new to the board and have a question regarding the Magnaflow 3" exhaust system. does anyone have it on their car and if so how was the fitment? Thanks

I have the 2.5" system. It's a little close in a few areas but doesn't hit. I did have to move my emergency brake cable a little. It's a great system, I really like it and get lot's of compliments.

I have a 302 convertible and I regret putting a 2-1/2" system on it. Fitment is really tight on a vert. Unless you're running a high performance (really high-performance) engine, I think 3" is way overkill. There's even evidence that running pipes that are too big hurts performance more than it helps.

First set of 2 1/2" did not fit over the rear axle drivers side. Second set not much better. Ended up taking the whole kit to a local muffler shop who scrapped the the Magnaflow pieces over the axle for their own hand made pieces.

 

Engine is stroked to 408, sounds great. 3" would not fit on my car.

3" makes no sense unless you're running something way bigger than a Mustang ever came with.

 

Is the Magnaflow kit a cut and weld deal or is it bolt on?

Thanks for the info, I am currently running a Coast Performance 427 windsor so I thought the 3" would be better. it may not be needed but it would sure be cool looking and I like the idea of a complete stainless exhaust system weather it be 2-1/2 or 3". and even if it hurts performance a little the car makes probably more power than I will need.

I am running the 2 1/2" stainless kit as well and it just barely fit, I have to take it to a shop this week and have a couple of pieces "tweaked" to make it fit without hitting anything. Sound is great, but I do not think I could get a 3" in. Mine is a 69 fastback with a 351W stroked and bored to 428. I actually was able to drive it a bit a few weeks ago for the first time, but I need to adjust my brakes some more as I am not getting enough pressure to the rears.

I am running the 2 1/2" stainless setup from magnaflow. Click on my link below and there is a video of how it sounds pulling out of my garage. The fitment is good on mine, but I had my local muffler shop do the install.

 

351 Cleveland with long tube ceramic headers. My exhaust dumps right after the mufflers...I didn't want any pipes coming out of the rear of the car.

Sounds great! I have the 2.5 inch Magnaflows and some shorty Heddman in the box waiting for my 393 stroker to arrive. I hope it sounds as good as yours!:biggrin:

xsuperjoex, car does sound great, do you have the stainless tailpipes that came with the kit and if so would you be willing to sell them? I am currently running 3" mid pipes with cutouts in them into 3" flowmasters but the previous owner installed 2" tailpipes with the stock mach 1 tips to keep it stock in apearance, the 2" tailpipes I think are too restrictive. Thanks

Thanks everyone for your comments. Here is a video from inside the car going from 20-100mph. Excuse my brother who is a little over enthusiastic about the whole experience. :)

i installed 2.5" Summit Racing dual exhaust on my 302. everything fit well. Because the gas tank is slightly off center towards the drivers side, the exhaust on that side is slightly angled up wards at the tips. had to do some jerry rigging to get the hangers in right. i agree with not going above 2.5". Unless you are racing the car regularly, you'll kill your performance and 2.5" is a really tight fit as it is. my two bits...
