2001 Sig. 500hp ism straight pipe

[Romeo84]

Hey guys I had my flex pipe under the motor between the muffler and the  downpipe fall off on my drive home this weekend. 

Seems like it's a pretty standard part but if any one has a part number that would be cool. 

Real reason for the post is Does anyone have a picture of their rig with a straight pipe.  

After hearing her roar Like that, I kind of want to put a straight pipe on It. Looking for pictures and parts they used. 2001 sig ism .

Thanks in advance

There was a post someone on this topic in the last couple of years.  I was looking at it for my 2001 Signature.  I had other things more pressing at the time, however was thinking in the future I would need to address this issue also.  It was a good post with options for mufflers and videos of the sound.   I have searched and can't find it.  I was thinking it was on here or IRV2.  Anyone remember this.

This is the muffler I put on my ISM500

I would also post an audio clip, but it sounds very much like Bliksem's...maybe a very small touch less muffled.

Where it sound neat (and the only time I hear it in the driver's seat) is going up Vail Pass thru the tunnel and floor it 🙂

 

It is straightforward plumbing job.  Just measure your sizes, get pipe / adapter / clamps to match, get some quality hangers, ensure you are connecting to something solid, put some rubber isolators in the strap and go for a drive.

On my 2001 Monaco we found that the exhaust piping needed replacing all the way back to the turbo, a big hole had blown thru the pipe next to the block.

I removed my muffler (full of holes) and installed a straight exhaust I picked up at a truck repair facility. It was intended to be installed as a straight up exhaust on a semi. Goes from 5" to 7" all chrome and truly straight. Had to build a new support system for it and ran it straight out the back. Had to modify the fiberglass where it exits from under the rig. Saw the same exhaust at a chrome shop on I-40 in Texas last year. Has a beveled tip, looks and sounds awesome! It's a little dirty right now. On a trip for the past 2 months!
