Any negative side-effects from raising the rear 1 or 2 inches for exhaust clearance?
So, now that my engine is done, I need to work on the rear. I'm swapping the 2.73s for 4.11s, but also, would like the rear to look a *bit* more aggressive.
Then I remembered that my exhaust guy said it would be too hard fitting 3 inches over the rear axle, and we settled on ending the exhaust with a glass pack and a downward angle just before the rear axle. Well, it's a tad too loud for a DD imo, and would definitely like to go back to the original plan of putting the 3 inches over the axle, and maybe into a 1 in, 2 out muffler.
I figured that maybe if I raise the rear an inch or two, that would be plenty of clearance for the exhaust, and would make the rear look a tad more aggressive.
Anyone ever seen or done this? Any negative side effects? I figure with only 1 or 2 inches it wouldn't be dramatic enough to look bad, but I can't know unless I see it.

But a single 3" is factory sized and even 3.5" and 4" single exhaust systems fit if they are done properly.
No reason to raise the car, honestly...

I have a Hooker 3" on my car; fits like a glove. No raising required. Fits exactly in the stock location.
I'd STRONGLY suggest a boxed-set approach from a major mfr like that, as opposed to a "custom" muffler shop setup.

Can you buy a full, 3 inch, "headers to y-pipe to straight over the axle to catback" that fits with aftermarket headers? I have hooker shorties, with one side different to clear the clutch slave cylinder.

The above is direct fit--no modding, cutting, bending, etc.

Yup.
I have SLP 1¾" headers with their included Y-pipe, a similar Catco cat as James except mine is the 4-bolt-flange one, and I think that same Hooker part # he listed. Bolts up as good as if not better than stock.
Not sure about anything having to do with "slave cylinder" making any difference. The above fits fine with both a T-56 and a T-5. If however, you have some random headers that you already know fail to fit the car, all bets are off. Might be a good idea to start over in that dept with something that actually fits the car, and then exhaust that fits the car will pretty much be a slam-dunk certainty that they'll fit that too.
As far as buying something off-the-shelf to fit whatever random headers you now have, that's impossible to predict. My gut however doesn't feel warm or fuzzy about it.

Find a new "exhaust guy." if he can't fit a stock sized exhaust on the car then he's either incredibly lazy or incompetent.
