zeroburn Posted January 4, 2003 Report Posted January 4, 2003 Does any body know the size of the stock exhaust piping? On another note, does anybody know if the stock down pipe from a 3.8 will bolt up to a 3.4 DOHC engine? Quote
Redfox340 Posted January 5, 2003 Report Posted January 5, 2003 Zeroburn, It's 2" in diameter for the W-Body. (and for most GM's right?) Nope, Patgizz, you're right... 2.5" As for the downpipe from the 3.8L, that's a good question to ask RedZMonte of M and S Production. RedZ, got some info? - RedFox340 Quote
zeroburn Posted January 5, 2003 Author Report Posted January 5, 2003 The reason i ask is because i found some nice stainless steel down pipes that are for the 3.8, but if they fit or are the same thing for the 3.4 DOHC engine and others that would be great. Quote
patgizz Posted January 5, 2003 Report Posted January 5, 2003 the stock exhaust from my 91 3.4 cutlass was 2 1/2" and stock my 94 lumina 3.1 was 2 1/4" i can tell you for sure the 3.1/2.8 downpipe is different than the DOHC one. cant say for the 3100/3400/3800 Quote
Robby1870 Posted January 5, 2003 Report Posted January 5, 2003 yeah my 3.1L stock size was 2 1/4". I wish I knew about the down pipe question Quote
