Im sure this thread is somewhere but googling and searching has lead me no where. I currently have HKS Hi-Power on my vert with a rocket bunny rear bumper. I cant extend the muffler far enough to clear the bumper as much as i would like. this exhaust doesnt owe me anything and before i start looking into generic mufflers with longer tips, anyone know of a cat back that clears aero? i know there is a tanabe? or someone that makes a cat back with an adjustable tip but it ran 1K.

Sorry if this has been asked 10000 times.

Im having the same problem currently. I just installed an origin rear bumper, and now I have to chop up my brand new hi power to make it fit -_-

Yeah thats my dilemma, it doesnt look like i have enough space before the muffler hits the sheet metal though. Id rather sell the Hi Power and just buy something that fits.

cut the muffler piping, add pipe length, reweld hangers... thats about your only option unless you wanna go find the discontinued HKS titanium based exhaust that had an adjustable length tip made for aftermarket bumpers.

catbacks are built around using the OEM rear bumper... not aftermarket bumpers.

Weld longer pipe to existing exhaust. Rocket Science.

I've got the Apex-i Ti, which has the extendable tip as well, but it is pricey. I was actually thinking of selling it, but I think I'm going to keep it until my build is done, and see how it looks since I'm running aftermarket aero as well.

The point being that HKS muffler has such a huge diameter, it will hit the body before it gets out far enough or you have to hang it low enough to clear that and will look terrible.
