Hi new to this board,
I purcahsed a Catco direct fit with the DynoMax cat-back. The catco inlet is 2.5 however the outlet reduces to 2.25. The dynomax is 2.5 all the way to the exit.
Should I cut the 2.25 section off the cat and make it 2.5 all the way through or should I let it reduce to 2.25 then increase back up to 2.5 at the DynoMax.
Are there any benefits one way or the other? Will I even notice anything if I cut the 2.25 section off (this is the way I'm leaning).
Thanks
Mark
