I ordered the wrong size inlet, like a dumby. The piping is 2.5'' and the inlet I ordered is 3''. Can the exhaust shop make it work? It looks like all they would have to do is weld a new 3'' pipe from my pre-cat running into the Flowmaster. Do you guys think this would work? I'm going tomorrow to have it put on but I wanted some ideas in case I just made a $100 mistake. I'll need to see what Jeg's return policy is. I already took the muffler out of the packaging. I would really rather just make it work than send it back.

I've never dealt with a professional exhaust shop like this before. Will they know how to make it work? The only thing I can think of is like I said, weld a new 3'' pipe from my pre-cat running into the Flowmaster.

Oops.

 

I did the same thing with my flowmaster. what the exhaust shop did was just crimp the 3 in pipe around the 2.5 and then they welded it together. not exactly what i wanted but it worked.

 

That should be no problem for a shop to handle. Most auto parts stores have a selection of adapters to correct problems like that as well.

 

The exhaust shop can easily make it work. Had a 2.5" outlet muffler expanded to fit inside a 3" dia pipe already. A hydraulic expander does the trick.

 

You wan the shop to keep a long straight 2.5" run, then step up to the 3" right before the muffler. I'm not sure what engine you have, but chances are 3" is too large for the section in front of the muffler.

 

Thanks everyone.

The exhaust shop made it work. And it all looks good. I have a YouTube vid uploading right now. I didn't rev it much, I didn't know my mom was going to take it.

Guys, I can't tell you all how pleased I am with it. I FINALLY got my 300 I6 to sound like a V8. You won't believe me unless you hear it in person. The video was taken by a digital camera.

Even one of the exhaust shop guys said it. "300's are hard to make sound mean. You hit the nail on the head with this one, though." Several other people said it sounds good.

Ah ha, and here's the vid;

YouTube - Finally got it!

$110 for the work, $100 for the muffler from Jegs. The man who done the work really did a good job.

Alright guys I need to go. A hurricain may hit us tomorrow so I'm off to get gasoline. You all take care!

 

Good work, that looks very nice and sounds good.

 

Thanks a lot Beat River! You have no idea how much I messed with my exhaust untill I got it just right. I-6 motors just sound different.

 

6 Cylinders in general sound different, but yes, I have heard the I6 is a different beast. My 4.0L V6 in my van with the exhaust I have sounds a lot like a V8 most of the time. I got lucky however, and only need to do it once. It just sounded right the first time.

 

Sounds great.

 

Thanks Sycostang! I'm loving it. I have to wear earplugs on extended trips but on the bright side I can't hear my loose dash!

 

Thats actually pretty similar to how I did the exhaust on my first truck, an 83 F-100 with a 4.9. I had the cat, a 12" glasspack and then one of those late 70's Trans Am exhaust tips that I used to split the pipe and run duals out in front of the rear tire. It didn't sound quite as good as yours though.

 

Did yours drone really really badly in the cab? I can't figure out why mine is so loud. I was really hoping by running the pipes past the cab it wouldn't be loud. Wrong.

The reason yours may not have sounded quite as good as mine is because of the cat. I no longer have any (the first cat is supposed to be gutted, but I'm not so sure). Cats kill the tone more than anything, and make it much much quieter.

 

I had 33's on that truck too so the whole truck was pretty noisy on the highway. I also had smog testing back then, so the cat had to stay.

 

So much for the radio, huh? lol!

Is your current truck with the 460 and stacks noisy in the cab? There's a Cummins powered flat bed pickup that goes up and down my work place. The truck has dual stacks, like yours, only his truck is a single cab so the stacks are RIGHT THERE by his head. I noticed one day his truck was not loud like normal. I guess he put mufflers on it or something!
