Subject: My modded mufflers are much quieter than I was expecting....... Author: rhett : member since March, 2005 : 1455 posts Posted on: 2005-10-13 23:03:57

Finished getting everything back together tonight (tranny,waterpump, and the exhaust).

Here are a couple more pics of everything

New internals of the muffler:


And to compare to stock:


It was about 10pm when I took this pic, but the car is not in the garage anymore



When I first started it to top off the coolant, I noticed how deep the exhaust is now at idle. Its not "loud", but has a very low frequency - sounds nice at idle. Sitting there and revving it up to 3-4k - has a strange (differnt but good, almost exotic to me) sound to it, hard to describe, but its still not loud at all. Went out on the highway and its no different than stock at 80mph.

I haven't done a full throttle acceleration run yet even though Kirt said there is no break in period on the tranny - I can't bring myself to do it yet.......

I will be doing a full write up this weekend and putting all the pics in order, but this should do for now.

2000 740iL - 140k+ miles, stock other than 2 10" JL audio subs and big RockFord Fosgate amp :)
5% tint back 3 windows, supposed to be 30% on front doors (might be 20%)
