ITR exhaust+ custom

Is this a good idea?: I recently spotted a crack forming around the weld on my twin loop's inlet. and I just dont like the way the muffler shop did the piping (air restrictive). I was looking into a hi-flo cat, 14" resonator, then the ITR muffler. but the thing I'm unsure is the dc headers collector size, because I'm trying to be wary of bottlenecking anywhere. hopefully the ITR exhaust can be welded on though :???:

when you get all that done just make sure they dont use smaller id pipes than th header then u go no problem. no point of even posting this

but if u do the work in sac i know a shop who did the work for my homies gsr'd sol 3 inch pipes all the way back plus exhaust for 220 its a pretty good deal.

i think the muffler is a 2.25" inlet, so wouldnt that create a bottle neck between header and cat?

I'm not even sure what your asking.

lol let me rephrase. right now i've got the twin loop, but the weld is cracking so I was looking into another custom piping exhaust done. I've got the DC sports ceramic headers (I think it has a 2.38" collector, not sure about this though), and I was thinking of redoing the exhaust using an ITR muffler+custom piping+hi flow+ resonator.

If the header's collector is a 2.38" does it create a bottleneck with 2.25" hi flow? Because I believe the ITR muffler has a 2.25" inlet. Correct me if I'm wrong about that...

o yea, this is for a 91 LS.

DC header is a 2 inch collector, so you'll be all set.

ohh awesome thanks for clearing that up tegsox !
