New Magnaflow Exhaust

vortec4800 · January 16, 2003

Just got my Magnaflow Dual Exhaust installed a couple days ago, I love it - sounds amazing... Its got that nice gurgle sound without being too loud, and when I'm cruising around town I can't hear it at all from the inside. I would suggest it to anyone looking for a mellow but powerful sounding exhaust when you get on it.

I totally agree with you. I just had Magnaflow muffler install in my GMC 2002 Z71 couple weeks ago and it sounds great. Quit in the cab and a very nice deep tone outside.

Is there any noticable loss of low-end torque? I'd love to put a mild muffler on my truck, but I can't afford to lose any low-end grunt at all...

Are you all talking about true duals (two mufflers) or are you talking about the single muffle (two in two out). I have a 8.1 with the 2- 3" in and the 2- 2.5 out and it sounds great. I was impressed with Magnaflows ability to make it so quiet inside the truck and at idle. I noticed mine has gotten a lot louder after about thre or four months. Magnaflow has out done themselves. Cost wasn't to bad either (225.00 including both tailpipes installed)

petemata, do you have the part number for the muffler? Any low end loss??

It seems like there might have been a little bit of low end loss, but my truck seems weird in that sometimes it has a lot of grunt and sometimes it doesn't, regardless of temperature or conditions like that... It seems like it might rev up a little slower if anything - but I was mainly going for a nice sound instead of a powerhouse.

It is not a true dual system, its one muffler that goes out the rear in two spots. Looks really nice, I'll take pictures and try to get some sound clips if I get a chance or if you guys express interest.

I actually heard that a true dual system isn't as good for these trucks as just the single like that, though I may be wrong... Hardly had enough cash to do a single muffler let alone two

According to the Magnaflow website, they only have side exit pipes. The tail pipes are 3" and have a 4" tip.

Costs??

Yea, pics would be nice.

Shane,

As you know, I had 2 mufflers/2 exit pipes put on mine with turbo(not Magnaflow) mufflers. I didn't notice any loss in power. I have 2 1/2 inch pipes coming out of the mufflers then into 2 3 inch 22 inch long tips that exit on each side of the rear tires. Sounds great outside. No interior resonance. I also have a FIPK and HPP programming as well, and can say that it is a nice improvement over stock. That might be a little more than you're willing to do though. It can add up quick. But if you're just interested in the exhaust, you shouldn't see or feel any decrease in power.

I have 2 40 series flowmasters if ya want em! (They were freaking loud. Interior resonance was aweful)
