Alpine Muffler

Was under the Alpine yesterday installing a trailer brake controller (thanks for all the tips, there was an extra wire running the length which sure made for an easy job).

one thing I noticed is that the muffler is TRASH!

does anyone know a part number or where to get one, or a suitable alternative?

thanks

I replaced the muffler on my 2001 Alpine with a Aero muffler AT4040. You can get one for about $100.00 online. Once installed my boost pressure increased by about 2psi. The increase in noise was minimal, and I do notice any noise increase while driving.

Go stainless with a life time warrantee. Magna Flow is a good product too.

Hello Aaron; I had to go take some pictures so I could post them. I used a tight 90 degree 4" elbow, and welded it to the straight pipe. If I were to do it again I would get a tight 90 degree with an expanded which would slide over the 4" straight pipe. I have found them on the net. I welded hangers on the old muffler hanger and exhaust U bolts to attach to the new muffler.

I hope the pictures explain what I am talking about. If you more questions please let me know.

Do a search Exhaust--MuffleróReplacement This muffler woks great for me. It rumbles a little but is quite in campgrounds. It's very loud when going through tunnels up hill - downhill is no problem. I mean very load, but I don't go through many tunnels.
