will 3" fit?

[tlandrum]

hey guys,
been lurking around here getting info for a build i a m doing for an old hod rodder wanting a sleeper. i put a a tall deck 427 stroked to a 496 in an 81 supreme. man what i tight fit. he wanted to keep the air and man was that a pain to work around. but all is coming to an end and i am needing exhaust. this beast needs 3" and i cant find anyone who makes a system for it. i can find 2.5 but thats a no go for this motor. motor is a 496 10.5 to 1 with grumpy jenkins 345 heads,comp custom grind of 306 ,310 and 715 lift on a solid roller. has a dart dominator intake with a 1050. so definately needs 3". has any one used 3 and are there any issues with clearence. thanks for any help

I have a full 3" system on my 442 from TorqueTech.
It was a bit pricey, but it fit well.

I'm running mandrel bent exhaust. With a notched crossmember it will fit fine. Cleareance over the rear axle is the tightest spot. It can be done. I don't know of any kits that big, you will most likley have to have it custom fab.

pypes sells a 3" xpipe system and a 2.5" you can get with many different muffler options or none at all and also your choice of ss or gn tailpipes

the 3" kit for an A body from magnaflow will work . the nice thing being that it all slides & clamps together & if you need to pull the transmission out, it all just unbolts easily !
