Hey Steve what muffler did they put on there?

It's the SGF70 system which uses a crossflow that flows straight through from side to side. The driver's side goes straight through the top and out the other side and the passenger side goes straight across through the bottom. It's not like a stock transverse muffler that just dumps both into the muffler can.

Well, I finally got some new tires for the Gramma car. Discount Tire Direct was having a sale with $50 off a set, plus another $50 off if you used Paypal on ebay, plus another $50 debit card rebate from Nitto and free shipping! So I ended up getting the tires at around $97 each instead of $140.

Those BFG G-Force T/As were just too darn short for the wheelwells. They were 275/40xZR17 and only 25" tall. The replacements are Nitto 255/50xZR17 which are 27" tall. Nitto seems to be the only company that makes a reasonably priced tire in that size. So instead of 2,800 rpm at 60 mph, it is now 2,600 rpm at 60 mph. And the best part is that they fit the wheelwells properly.

So, with that in mind does anyone need a nearly new set of BFG G-Force Sport T/As in 275/40xZR17 with around 500 miles on them? These are the same size that came on the 1998 to 2002 Camaro SS and Trans Am WS6, by the way.

Looks really nice Steve!

Thanks, It rides a lot nicer now too. I think old cars like tall sidewalls. The 40 series tires seemed to feel like they would follow any road defect - kind of like driving on old bias ply tires.

The new tires really fill out the wheel wells nicely!
