[baios]

here is what my m38 looks from behind my friend who help me with the restotation told me that he has put a muffler from a m38a1 and thats why is longer thn the original!!!!But this is very ugly and o don't want to have as it looks!!!!So i must change with the original. my question is if realy there is difference between the two mufflers? any ideas????

The M38, M38A1 & M170 all use the same muffler ORD# 7375076 and the same front head pipe ORD# 7375077.

The M38 has an 80" wheelbase, the M38A1 has a 81" wheelbase and the M170 has a 101" wheelbase. The middle pipe differs in length on each:
M38 ORD# 7375078
M38A1 ORD# 8329739 (1 inch longer than previous pipe)
M170 ORD# 8333278 (20 inches longer than previous pipe)

I was able to provide you with this answer simply by looking the part numbers up in Both ORD 9 parts books. You can do this if you have both parts books. They are free here on our web site's downloads page:

M38 ORD 9 SNL G-740 - http://www.willysmjeeps.com/v2/modules. ... tit&lid=95

M38A1/M170 ORD 9 SNL G-758 - http://www.willysmjeeps.com/v2/modules. ... tit&lid=87

Η (M38), αγωγοί, Μ38Α1 & M170 όλοι χρησιμοποιούν το ίδιο σιγαστήρα ORD# 7375076 και το ίδιο κεφάλι εμπρός σωλήνα ORD# 7375077. Ο M38 έχει μια 80" μεταξόνιο, το M38A1 έχει ένα 81" μεταξόνιο και η M170 έχει 101" μεταξόνιο. Τον ενδιάμεσο σωλήνα διαφέρει σε μήκος για κάθε: M38 ORD# 7375078 M38A1 ORD# 8329739 (1 ίντσα περισσότερο από προηγούμενες σωλήνα) M170 "ORD# 8333278 (20 ίντσες περισσότερο από προηγούμενες σωλήνα) ήμουν σε θέση να σας παρέχει με την παρούσα απάντηση απλά κοιτάζοντας τους αριθμούς τόσο σε ORD 9 τμήματα βιβλίων.

have qe got the measures from the m38 muffler??? i will go and measure that muffler that is in my m38 and see if τhis is from m38a1 or from another car and my friend just said to me lies!!and also the measures from the middle exhaust pipe extension if there is the problem

The three mufflers are all the same length. It is the middle pipe that must be measured.

Οι τρεις κασκόλ είναι όλα το ίδιο μήκος. Είναι το μεσαίο σωλήνα που πρέπει να μετρηθεί.

The problem is not the muffler. You have the M38A1 long extension pipe on the M38 jeep and it is longer than the M38. The muffler was the same between these two jeeps as was the header pipe. The difference is the long extension pipe between the muffler and the header pipe.
