Personally I would just get the right muffler for the right car... no point in trying to adapt it... you will lose power, might not get the right sound and will certainly not get the full benefit of having a remus muffler. ← agree totally! ← Triple agree, If it's from a 307, it means it's specifically for that model, add it to yours and you wont get the same result as that specifically for the Corolla. ← thanks for u opnion guys.. might just forget it then :) what about the apexi WS muffler.. would u think it'll be better than the remus?
