exhaust

i have a "82: camaro z-28, and i'm planning on putting custom duel exhaust on it, the shop i'm having it done at says they will run 2 pipes side by side (2 1/4")on the passenger side (jump the driver side over the drive shaft) and split them up past the rear end. (clearance problems , makes sense), but then i talked to a buddy that said he did the same thing on an "86" and ended up smashing the exhaust, i didn't get the details how or why it smashed... so my question is has anyone put duels on their camaro and had any clearance to ground problems, or should i just stay with the single exhaust and go with a bigger pipe?

Yes dual exhaust can be fabricated to fit a 82 Camaro following the stock exhaust path pretty close. Ground clearance is not an issue when done right.
I have a custom made 2.5" dual exhaust from front to back on my 88 Firebird.
With dual transverse mounted turbo type mufflers mounted behind the axle in the stock position. Its a lot lot of work to do right. Its tight. very tight.
You cannot bend up a system like this that fits well. It has to be custom welded up using mandrel bent pieces of bends and straights. No Exhaust shop is going to do this for you. Not for any price you can afford. It takes way too long to fit and fabricate it properly.
Do not waste your time or money. Get a shop to fabricate a 2.5" into 3.5" 2 into 1 big pipe exhaust system using a Flowmaster #Y250350 Y collector, 2.5" pipes off the long tube headers and a 3.5" main pipe going back and over the axle on the passenger side. There is even enough room for twin small case cat converters before the Y pipe, but its tight. The trans cross member needs the flange edges trimed to allow the pipes to be snugged up close to gain the best ground clearance. use welded up mandral bend pipe curves ( Dyno Max parts) You can mount a big 3.5" in/out Flowmaster or MagnaFlow muffler transversly across the back behind, the axle and add a 3.5" tail pipe to exit under the rear bumper. This exhaust system will support up to 450hp without much restriction at all and reasonable noise level Just as good or better than dual ex will.. And fits the chassis much better than a dual exhaust system on these cars.
A 2 into 1 big pipe system is defiantly the way to go on these cars.

This is the general idea for the head pipes and Y pipe. this is for a 4th gen Camaro. Yours will be similar when done.
