Hey all,

i just bought an ITR muffler for my planned exhaust setup for my 95 LS. I was going to fit it to some custom 2.25" catback piping for a light mod. Over the research i've done on the topic of using an ITR muffler on other dc2's, it states the ITR muffler has a 2.25" inlet, which ties into the ITR catback piping size as well. Problem is, the ITR muffler i've just bought measures a 2" inlet (this is measured right at the inlet hole, where the bpipe and other piping has been chopped. I only purchased the muffler itself.)
Now people might suggest I've bought a bogus muffler, but I got it from an acquaintance, and also, it looks EXACTLY like the muffler in this post--->

If anyone could shed some light on this it'd be greatly appreciated. A friend suggested that the '96 ITR muffler could have had a different sizing, or that the muffler is in fact a 2" inlet, tapering from the 2.25" system?
At the end of the day, if i fit this to my original plan of 2.25" catback, it'll be a waste of time correct? As in the 2" inlet muffler will merely "choke" or bottleneck my little modified exhaust system?

thanks in advance guys,


Jon

 

see link in sig, check the specs section.

 

Dude i just checked out your "specs" section.

There's nothing there that helps me.

 

I have this saved in my notepad, but it's regarding the exhaust. It was posted my SMSP.

Stock ITR is 57mm OD (2-1/4") with multiple bottle necks. The worse being at the B pipe inlet which is 1-3/4" ID. The B pipe necks down to around 2" or 2-1/16" OD at the B pipe to Axle back joint and the muffler tubing is 54mm OD and then necks again to 52-53mm right before it enters the muffler.

Awesome, thanks for that. I suppose I'll sell it and find something with a 2.25" inlet.

cheers for your help.

 

Why not just remove the bottleneck and weld on a larger pipe? I did it with the inlet to my B pipe with a pipe from SMSP.

 

why not go 2.5"?
