Quick Q;
Following on from some previous mods, I noticed that i still had the OEM shielding around my up-pipe, and thus am led to believe that I still have the OEM up-pipe, to which in the MY01s, have an additional cat in them. I do not like this.
So, next mod is to pull it out and replace it with an aftermarket one. I have had a look at a few, Perrin Vs Grimspeed.
One has a flex joint, the other does not. Do we need, and is it recommended to have a flex joint on the up-pipe? I was keen to wrap it, and the flex join presumably should not be wrapped.
Grimspeed:
$300.00
Perrin:
$340.00
What are the feels on these up-pipes? Assume this will also require a re-tune afterwards. Anything else in the market that is worth considering? Should I look to ceramic coat instead of wrap, or both?
Keen to keep temps down and this is the hottest part of the exhaust.
Cheers
