Hello,

thank you for your enquiry.
All our tips are made of Stainless Steel AISI 304.

As for the difference in mounting, the tips for welding are supposed to be welded into the back box. So you cut off the original endings and weld our tips in their place.
This is however not possible to be done in all cases, as those tips are 20cm long, so if your back box is further than 20cm they will not show under the bumper. Second thing is not all back boxes are suitable for such procedure - this is mostly determined by the shape of the back box.

The other type of tips - the universal ones  have an assembly cup, which ranges from 45mm to 60mm max. Please note that not all our universal endings are offered in the full range of assembly cups (this is shown in our offer). The stainless steel piece is usually 12cm long and then there is an aluminized steel assembly cup (usually 6-8cm long) this cup can be easily reduced by cutting it of. This way you can make the tip shorter to adjust the length.
This type of tips are to be put onto the existing tailpipe. We give the inner diameter of our universal tips assembly cup, hence is your tail pipe has 55mm outer diameter, you choose a tip with an 55mm assembly cup.
Please note that if the tail pipe diameter needs to be even in order to slide our tip onto it and if it is not in the straight line the tips will also not be in the straight line
