My True Dual 3 Inch Exhaust
This is pretty much in the stock location, although i did do a bit of hammering to the floor pans to make it fit.

Re: My True Dual 3 Inch Exhaust
Looks a little illegal without the cat. LOL. Just kidding man. That looks cool as hell man. Are those Borla mufflers? You may wanna fab some Turndown tips so that the hot exhaust does melt your rear bumper.

Re: My True Dual 3 Inch Exhaust
i figured the cat was the least of my worries when i had a 13 to 1 compression 454 running on leaded race gas, and i have a set of turn downs on it now, the exhaust was turning the rear bumper all black and sutty

Re: My True Dual 3 Inch Exhaust
Good ideas there!!
Got more pics of the passenger side frame rail modifications?
Got pics of how you got over the axle with dual 3" pipe?

Re: My True Dual 3 Inch Exhaust
Whoa... That looks great! Either that camera handles loud sounds really well, or its got a pretty nice tone/db to it! I was expecting the camera mic to get blasted out when you revved it.
I think I speak for everyone...when I say Ide like to see some flybye and in car vids of how that sounds!!!
Great work!

Re: My True Dual 3 Inch Exhaust
Very nice work and welding man,the only thing I'm not in love with is the mufflers at the rear, but you do have them tucked good.
Re: My True Dual 3 Inch Exhaust
Nice design.
Where any mods necessary to the panhard bar or brace where you go over the axle?
Is there a chance of clear look at how it follows the torque arm and driveshaft?
It's getting me to thinking of better ways to incorporate a pressure wave tuning chamber into one of these cars.

Re: My True Dual 3 Inch Exhaust
Very nice. The only thing I hate about these cars is the spare tire well does not allow even placement of the mufflers in the rear.
