edelbrock sdt muffler discontinued?

Hey everyone. Quick question... I'm trying to purchase an edelbrock sdt muffler with a 3 in. inlet and dual 2.5 in . outlets but am running into roadblocks left and right. The part # off of edelbrock's site is 55763 but I can't seem to find this anywhere. Even when i finally thought i found it i received an email saying that the part was discontinued.

can anyone verify this or shoot me a link to where it is. it might mean that i have to buy the whole catback which is something i'm trying to avoid. my pipes are in good condition and i plan on deleting the cat anyway. thanks for your help

brian

Re: edelbrock sdt muffler discontinued?

Here's one that's 2 1/2" inlet and 2 1/2" dual outlet http://www.summitracing.com/parts/EDL-55762/

Looks like it's been marked down. So maybe they are getting discontinued.

Re: edelbrock sdt muffler discontinued?

thank you..a bit to raspy for me.(school bus sounding).
Do not take that the wrong way!!!
ill stick with the RPM muffler.

with a 11.1 and mech cam..the edelbrock RPM Muffler. sounds fantastic.
but that's Just Me
3" in 2. 2 1/2" out no raspy school bus sound..

Re: edelbrock sdt muffler discontinued?

I actually wound up buying the whole system and i have been 200% satisfied with it. It sounded better than i thought it would and it came with 2, 24in by 3 in. polished stainless tips which IMO look great. the install was pretty straightforward. i'll post some pictures/videos up when i get a chance of before and after.

as for the name of it. if you read correctly the muffler is sDt, not sTd. I believe it's Sound Deflection Technology

Re: edelbrock sdt muffler discontinued?

Personally, I like the RPM more than the SDT... When I bought my RPM, it was right before they dropped the RPM and introed the SDT...

check my sig for links to a sound clip
