Gillet vf Bischoff Muffler - difference in fitting?

[chinoloco]

Hi All

If I currently have Gillet mufflers (I think they're motorsound, how can you tell?), can I fit Bischoff RSR mufflers? Is there a difference in the fitting? Am I likely to need new heat shields (90k miles), what happens if you don't use new ones?

TIA!

Yes you can use them as long as they come with the doughnut rings as that is the main difference between the 2 types

See if you access my photobucket site to see the two types next to each other

the heat shields are the same but are in need of replacing as they are nackered

Post the part n that is stamped in the housing.

what happens if you don't use new ones?

You risk melting the rear bumper and the tail lights.

The replacement heat shields are expensive. Chances are your old ones are toast. mine had disintegrated completely.

You do risk heat damage to the bumper if you don't replace them.

thanks for the replies everyone. 125euros for replacement heat shields from carnewal! any cheaper sources out there? begs the question if these heat shields fail on most 993s at some point why don't all bumpers melt?

do the doughnut rings always come with the gillet mufflers if they're original with the car? i have bischoff currently but would like to put gillet RSRs on, can you order the doughnut rings seperately?

Phone Gert at Carnewal,

he will explain about the doughnut rings and should be able to supply them.
