Going to start making an exhaust soon, what muffler dimensions/size?
I will most likely be going with a Magnaflow and was wondering what fits under there, what inlet/outlet/center/offset/dimensions/etc.
I will be doing new piping, most likely 2.5" does anyone have a good undercar shot of a 90q20v so I know what bends to order?
Thanks!

Why not the Vibrant 1134?

there's a thread on the 20v sedan exhaust option on the 20v list this week

than the Super Hemi Turbo (maybe superceded in name only by "Super
Turbo" style that has fiberglass matting as well (or at least a lot more
capacity for it) as in the 17748. I went for the Super Hemi style based
upon dyno tests and other reviews in an old issue of Hot Rodding or
some such thing (can't remember now).

> The Walker Dynomax 17748 is about $43 plus shipping from Summit and
is about 20" by over 25." IME size DOES matter.

> The 17748 is specifically marketed as having a "deep," "throaty"
sound so that may account for the somewhat "ricey" sound you describe from
the 17715. The fact that you paid more for the system than I did using
a rear muffler that goes for about 42% of the cost of the specified
17748 probably isn't good news for you either. Granted, the 17748 is a
tight fit, but it does work. It gets EXTREMELY loud after four years and
you blow out the rust hole when the car backfires. This will also
scare the living crap out of your German Shepard/Husky cross, but the
muffler can be replaced for such low dollars I'd do it again....and I did.
The dog will go near the car again after a few months.

agressive during wide open throttle and not intrusive towards other
motorists. I have purchased several other 'performance' exhaust setups, and
all of which performed the same but were very loud. The price is
excellent as well. (as low as 40 dollars on the internet).I paid 108.10
including tax for the muffler and installation. However, only time will tell
to see if this product lives up to its reviews. Dynomax claims to have
a lifetime warranty, but we will see about that.

p.s. your car leaking? There are spots on my driveway where your car was parked...I NEVER park on that side, so it's not mine.
