I am getting a cat back exhaust for the runner.

I am going to have have the shop use 2.25" pipe.

Mufflers: God forbid i ask about mufflers. but, I am thinking of the 40 series delta flow or a magnaflow 3 chamber. opinions. I have searched but many didn't give a definitive answer or opinion.

Thanks.

 

I like the 3-chamber Flowmaster (50-series) and the Delta-Flow version which is supposed to help reduce resonance in full bodied vehicles:

I had a buddy use a 40-series in his FJ60 and said it was quite loud inside on the highway.

 

alright, thanks 4crawler. I will see if the shop has one of those or can get one. i like the idea of no packing to blowout. Thanks

 

I got a magnaflow and i love it.



Don't mind i didn't make it up the hill, but you can hear what it sounds like on a 3.0

 

Alex,

In my '89 Runner I put on the Downey headers and ran 2 1/2" back to a Magnaflow cat then out into a Magnaflow #12577, Oval, 5x11", 2 1/2 in/out, offset.

It was too damn loud on the trail with the top off and in town I felt like a 16 year old kid driving a Honda. The cabin resonance in the Runner was terrible.

I yanked it out and went with a 70 series Flowmaster. That is their big block series muffler that advertises lowest cabin resonance. I really like it, and I got back a little low end torque. It has a good rumble to it, but I don't feel 20 years younger and want to turn my hat sideways.

I still have the Magnaflow, if you want it....

mmhmm. I am kinda looking for a better sound but not overly loud. the 50 series delta flow i guess is pretty quiet. might be worth a shot. thanks for the offer though.

 

4crawler has a sound clip on his site, but it's 22RE...

 

got the exhaust installed today. 50 series Delta flow with 2.25" pipe from the cat back. sounds great. haven't really noticed much performance when i drove it for a little bit, but that wasn't really a good test. very mellow sound with a good low tone. you can barely here it inside the cab unless you really romp on it. I would highly recommend this muffler for a stock replacement or if you want a good sound without it being loud or having the annoying tinny, sound.

I will try and get a sound clip here in the next couple of days.

 

Have a little interference with the vehicle height sensor at full compression . I will be shimming that a little bit rearwards to eliminate this problem. otherwise, it is very good.

 

Here is a sound clip.
