View Full Version : High flow cat + exhaust question

12-17-2005, 11:00 AM
Will the milltek high flow cat bolt up to a borla exhaust system?

I'm guessing no, since the borla is 2.25 and the milltek is 2.5.

But I thought I'd see if anyone was running it.

Thanks guys.

Well, if I'm not mistaken you can run the Milltek HFC with the stock cat-back and you can run a Borla cat-back with the stock cat. If this is the case you'll be fine. The piping is bigger on the Milltek but I believe the mounting flanges are the same.

that logic makes sense. can anyone verify that the milltek hiflow can be used with the stock exhaust system?
