Muffler help

[soobscript]

The tailpipe after muffler on my 88 RX has corroded through. Exhaust has deformed my rear bumper and eaten a hole thru the floor. Obviously needs fixed.

I got a Dynomax Super Turbo muffler new off ebay (mfg. link). It has center inlet and offset outlet (stock is offset / offset, top & bottom). 2.25" pipe both ends. Want to install it - if not possible, then replace tailpipe.

Stopped at two muffler shops for estimates to install. Monro said no way without extensive fabrication, no stock tailpipes available, different size pipes. Local (recommended) shop says no problem, maybe $50. ...But he didn't look at it on a lift, just on ground.

Problem is where pipe runs over rear crossmember(right name?), plus it's on a curve.

 

What is stock RX pipe size?

Can I use the new muffler backwards, with reverse flow? (offset inlet, center outlet)?

Anyone have experience with this?

Well because i dont own an RX, so this isnt definate, but the exhaust system is 1 & 3/4" or maybe 1 & 7/8"

Is it a straight through muffler, ie. you can see through it, in this case i know u can use it anyway u like.

 

Here is a pic of mine

I can't see through it, but I can see all the way inside from each opening. It does like an 'S' curve lengthwise inside. Here's a pic from the site, but mine is center/offset not offset/offset like shown.

 

Oh, just saw this...

Flow any direction (unless stated).

 

Heading to the muffler shop in a few.... *fingers crossed*
