Title: Gp4 Exhaust Post by: Nigel1967 on 11 September, 2023, 11:12:32 AM Hi all... I have a series one zagato which has what looks like a gp4 exhaust but has a silencer in the centre under the car and another at the exhaust exit.
The car is semi-track prepared and so is lower than standard so the centre silencer can cause ground clearance issues. The question is have is, should there even be a centre silencer or should they both be towards the rear? Many thanks Nigel.

I have that sort on standard cars but the one i have is a lot smaller than the traverse type. Maybe i have something that somebody thought was a good idea at some stage :) Thanks v much Title: Re: Gp4 Exhaust Post by: lancialulu on 11 September, 2023, 01:11:31 PM the centre silencer is normally transverse as Richard Fridd says and there should be a heat shield in front of the axle indicating location. Gp4 tended to have a more pancake silencer mounted to the side

By the looks of this photo, they should both be at the back. I'll see if mine has been fitted incorrectly. Thanks again cheps Title: Re: Gp4 Exhaust Post by: Nigel1967 on 11 September, 2023, 01:21:41 PM chaps even!

I guess it doesn’t matter as long as it fits. Where mine is lower than standard, if I’m carrying a passenger,sometimes over bumps, the axle comes up and takes the exhaust with it and causes the end pipe to knock on the rear valence. All the joys of a modified car I suppose . :) Thanks again for the info |
