Just thought I would share with anyone who's interested in getting a performance muffler for their T100. This is just a muffler swap, not a cat-back system.

I did some research on this forum and the 4Runner forum. Seemd the Magnaflow was a popular choice among the 4Runner crowd for their sound and performance. Assuming it's the same 3.4 engine, I thought it would be a good choice, but after having it installed this morning, I kind of wish I had gone with Flowmaster 40-series as the Magnaflow is almost too quiet. I think it's quieter on a T100 ex-cab because our truck is much longer than a 4Runner. It still sounds good, and seemed to have better acceleration at mid-range, but it wasn't what I had expected. The total cost was $100+tax for parts and labor as they had to weld an extra 6" pipe and 2 extra hangers to make it work.

What I found interesting is that our stock T100 pipe is metric, and its measurement is somewhere between 2.25" and 2.5" (which is not bad for stock).

I will monitor it's gas mileage to see if there's any improvment. I just need to come up with an excuse later for my wife on why I just spent a little over $100 to replace a perfect good muffler. <img border="0" title="" alt="[Eek!]" src="images/icons/shocked.gif" />

I did a similar swap on my truck a few months ago. I bought a Holley Flowtech muffler, a 2 ft 2.25" extension pipe, 2 hangers and some clamps - about $50 total. I had to get the pipe and one end of the muffler expanded at a local shop (+$10) to get it to fit the oddball size stock pipe. I probably should have got the aluminized version, but it wasn't in stock at the local Checker Auto. I turned the outside edge of the muffler up about 30 degrees to get the outlet to line up with the tailpipe, but it still has more clearance than stock. Mine isn't as loud as I thought it would be either, but does have a nice rumble. I did the same swap on my wife's '00 Dodge Durange, that 5.9 sounds sweeeet now...

I'll be needing a muffler soon.

Anyone try the basic Walker replacement system?

I was surprised to see that they the have an OE replacement for the 1995-1998 T100 with 3.4 engine for the converter and muffler.

I don't know their cost compared to Toyota OEM, though. Probably cheaper.

With Walker: what changed in the two parts of the tail pipe from 1995 to 1996-97 versions?

Or what did Toyota change from 1995 to 96-97?
