Vert bracing a problem for headers?

[Indydriver]

Researching header applications for my soon-to-be LS3 Vert and I'm beginning to read about interference from extra structural bracing for certain header applications.

I'm specifically looking at ARH LTs + HF Cats short connectors into OE catback vs. their 'to-the-axle' system into NPP. Anyone know if the latter has interference issues? If yes, how are they addressed? While we're at it, is there much difference in sound level between the two? Keep in mind this is a convertible so I'm looking for a mellow sound at least while cruising.

Thanks for the feedback.

Look at my sig. Been running ARH for two years. They are 2" also. They fit just fine.

By the way the corsa exhaust has no drone and is very quiet while cruising.

I had a rattle with my catback hitting the front brace due to the small amount that headers hang down compared to stock manifolds - got the arh chassis brace and no problems

I just got a response on this issue from my prospective tuner, a very well respected guy, who says regarding imstallation of the ARH 'to-the-axle' system:

I deleted the original comment posted here because it was wrong. Now, after discussing with ARH, my tuner informs me that the "to-the-axle" ARH system requires replacement of a chassis brace with their $475 replacement part. This is in addition to the $500 premium over the short connector LT system. I was willing to stretch the $500 difference in cost of the pipes but no way on a grand with replacement of the brace. So, its back to the short LT system leaving the complete OE catback in place. Oh well, probably be a little quieter anyway which will be better for my situation.
