I have bought a Piper cat back Twin DTM exhaust, an Arvin Timax CAT and also a SS Lexmaul Manifold thats all supposed to be fitted on Thursday but I just remembered that the manifold is 4-2-1 design and have noticed that the downpipe has a twin pipe welded together and is sort of ovalish in shape.
Has anyone had a similar setup on a vectra or similar, or can anyone see me having a problem ?
I better tell you also that I manifold hasnt arrived yet and will do on the morning of fitting hence my worry !
Don't know about this combination, but when I had my SBD manifold fitted I had to get a full new SS exhaust as well, as the std one is only 2" and the SBD manifold has a 2.5" output. However I think the lexmaul manifold is milder than the SBD one and might mate up OK. Even if not it is not a huge job to make a flange to connect them up. Any Powerflow type place should be able to do it.
