1G 1g Megan Racing downpipe and catback?

[bgold87]

Just ordered a 3" Megan Racing downpipe and Megan Racing catback. Is the dp cat eliminating or will I need a testpipe to get rid of cat?

The dp is just the down pipe everything else you can decide how you want to do your exhaust.

The MR 1g downpipe is not cat eliminating. You will need either a test pipe or high-flow catalytic converter.

From 1G Rally-Crosser:
1) Outside diameter appears about 3".
2) Inside diameter about 2.5" at Turbo flange, turbo is Stock 14b, as best can tell.
3) Flex appears to be very large and about 12" long(?). Will have to measure for accuracy.
4) System is fairly straight, most Pipe joints installed for best flow except for extension after resonator.
5) Mounted solid to floor pan, I ass-u-me, possibly , for less chance of being damaged/ripped off in Rally-Cross & less things to break.
6) Clearly, not a quiet system (FWTW)
