Just got a Flowmaster
Also one tip coming out the back of a T/A would be rice cake city.
So to add another tip would be a good idea, making it functional would be an even better idea. To do this the shop cut another hole on the inlet end of the muffler. Welded on a flange and welded to that another piece of pipe with a tip coming out the passenger side. There you have it, good ol southern enginering. And now that I'm thinking about it, the extra tip on the inlet side would probably help with flow if there was backpressure in the muffler. I do know for sure that it has a unique deep smooth sound to it. Also any concerns with flow could be solved by un-capping the cut-out. I feel like I got my money's worth and besides what's a muscle car with out a little bit of that southern enginering.
Thanks for your concern and what a great eye on noticing that about the 40 series Flowmaster.

thanks for clearing that up....
sounds like a good setup you got there...
Alot of mufflers sound good on the LT1, and sound like crap on the ls1. The LT1 is a totally different car than the LS1, and you can't even compare muffler to muffler on the two cars. It's like comparing the sound of a flowmaster on a 4.6 mustang vs. an LS1....totally different. The LS1's I've heard with flowmasters and stock exhaust manifolds sound like a V6. IMHO, it sounds like your runnin around with your tail between your legs. No offense to you guys who run them, it's just my personal opinion.
