Thread: Custom Exhaust System

Towed two different trailers yesterday and found that the new exhaust modifications are more noticeable when towing.
You can tell that it's breathing better, especially up hills. Very happy.
Still have to post some photos.

Cheers, Craig

I've managed to dislodge a baffle in my main muffler on my Simpson trip it now has a rattle / vibration at idle, so I'm looking at the best option to replace mine. Details please Craig?

Finally got around to posting some photos of my less restrictive muffler & cat



Cheers, Craig

Hard to guage the fuel at this stage Tombie. When I took the D4 in to get the exhaust done, I wrote down the Trip A speedo reading (bit over 4,000Klms). I intend to check the fuel usage once I get to the same 4,000 odd Klm mark.
Its hard with me, because I have 3 trailers and a boat. Some days I'll be towing a heavy with a load, others days, none.
I will say that it seems to pull better with the trailers.

Let you know, Craig

Hi Craig,
Has the note from the exhaust change either on the inside or outside of the car?

Hi Rich,
You can definately hear the rumble Rich.....sounds good. Especially under load.
The noise inside is barely noticeable at some speeds / revs. It is more or less a competition between the exhaust & the Cooper LTZ's. Nothing annoying though.
