Mufflers

gchemist · 06-29-2008, 01:35 AM

My Jimmy needs a new muffler this summer.
A single Magnaflow may be nice. I noticed the pipe goes down from 3" to 2.5" or 2". I can't remember if the down size is infront or behind the catalyst converter. I may go 3" all the way out.

What do you have on your door vehicle? Anyone have a suggestion?

A new highflow muffler is my final step to pick a little more MPG. The Jimmy already has a nice throaty sound at idle and off idle.

IIRC correctly, the piping is 2.5" from the y back...

I have a flowmaster 40 single in single out dumped right after the muffler and its loud, like almost to the point of being annoying

Yea, I had a single 40 on my full size 83. It was annoying on the road at 70 MPH. The 83 now has dual Magnaflows, x-pipe and no cats. Dump right behind the axel. The sound is very pleasing. At highway speeds, I can turn up the radio and drown out the sound. Not a lot volumn either. I'm leaning toward one Magnaflow and a high flow cat.

I can't remember if my Jimmy has 2 or 4 O2 sensors.

I have a 40 on my 93 blazer with no cat. its loud but i don't mind it. Its louder inside than out.

I had a super 40 3" in and out and it was too loud for me.

I changed over to a magnaflow with single 2.75 in and out and I love it.

I hear the spintech mufflers flow way better than the flowmasters. I am lookin for a muffler myself because im redoin my exhaust soon.

MY 40 DUMPS ABOUT 8" BEFORE THE AXLE AN CAN GET ANNOYING AT TIMES AND YES IT IS LOUDER IN THE TRUCK THAN OUT @ 70mph BUT IT'S A NICE RUMBLE @ IDLE.

i've got a Borla on mine... little bit of throat when you step on it, and nice little growl while idling

97 blazer · 07-17-2008, 10:04 PM

im running a magnaflow 2.5in/out w/a single 2.5" tail and it sounds nice...quiet w/a nice rumble @ idle but throaty and deep when i get on it. all my friends say it sounds awesome when i drive by them
