Im in the process of installing some lt's and since I already have the LMII catback ive decided to just have a custom ory pipe made to accomidate the catback. My question is should i have 2 cut outs ( one placed after each header) or will 1 in the I pipe work best. will the gains be so minimal that i wont notice them seeing as im basically stock. But for further reference I do plan on doing a full head and cam package as well as possibly nitrous in the future. Please someone tell me what would be best. PS im not worried about it being loud cats are definatly out of the question but a muffler change may be in order as i want loud but not an unrefined sound.

thanks in advance

if you put cutouts off the headers it will be ridiculously loud, i ran open headers for two weeks when i ran into exhaust probs and it was a nightmare..plus you have no back pressure....and i like loud but this was too much!! I say one after the y-pipe, it will sounds good and you will have enough back pressure.

I would go 2. Look at the QTP y-pipe and you can do something like that.

2 will be louder and will be worth a couple hp. 1 is enough though IMO.

2 > 1

Go with one after each heder...and go with the electric plates, so you can silence that bitch around 50.
