Ditto on the expanding - that is insane - why not use the right size pipe/muffler to start with??? That REALLY brings the competency factor down - I would be worried.

The muffler is not rubbing all the time, that is why you don't notice it, it is rubbing when the rear springs are compressed, and I'm sure there are plenty of other noises going on while you are playing "Dukes of Hazard" to cover up that slight rub. Either way - they need to fix that.

As far as not spending money trying to improve a 3.0L, that is probably the most ignorant post in this entire thread. Been there, done that, the 3.0L responds very well to minor mods.

For under $500, you will have a very responsive engine that retains its bone stock reliability - do not think for a second you will have the same reliability and power with a $500 V8 conversion - that's just not true.

Toss a tuner on there and you are still shy of $1000; now you have a decision to make if you desire more power: V8 or Forced Induction. That is more reasonable....

thats a muffler for a chevy truck, probably one of the easiest to get and the cheapest also.

it has a 3 inch inlet and 2.5 inch outlets and is actually hurting his 3.0 due to the oversize in's and outs.

i bet they did the same thing at the rear of the muffler also seeing as they used 2 inch pipes there.

so at the end of the day he has the wrong muffler and the idiot at the shop was to stupid to realize it or just didnt care and probley got a kick out of butchering his truck!

x2! I made the mistake of having my mother bring my truck to the exhaust shop to get welded up....i was using those stainless band clamps from jegs before. Evidently the same shop that installed the exhaust, including muffler mounted vertical, this time they decided to weld it horizontal. Yes....it did rub the shaft, but only when flexing. It was one of those Super 40 5x10" cases too.


I do really dig your turndowns/dumps....ican't figure out a dual out setup for mine that i like...i think i'll probably go straight out the back, at the sides of the hitch, but end it early with dumps....barely visable.

How much was yours?

I built mine using an aluminum one out of a Mark VIII. Ended up costing me $90 in total to have a 3lbs lighter aluminum one. I will probably spend $60 on making one for my 86 mustang from an aerostar d/s. Shortening/balancing is cheap where I live.

The real question is:

A 2 1/2" section of straight pipe flows 560cfm at 28" of water.

What do you think a 3" inlet flowmaster flows. I guarantee its less. I flowed a 2 1/2" 40 series and it only went ~345cfm @ 28" Thats like cutting out the 3" flowmaster and replacing it with a 2" pipe.

Oh man I was expecting flowmasters, not a flowmaster. jk

That's usually how they mount if you want a dumped SI/DO setup, dumped as in with turndows right after the muffler. I noticed that it rubbed sometimes on my ranger.
