rivierakid55 Posted September 25, 2006 Report Share Posted September 25, 2006 (edited) first wondering how much of a bolt in the dynamaxx long tubes and cats are and if they have the factory 02 bungs already in place. being here in california it is a must for me. also, it says legal for sale in california but is that strictly for smog and not for fittment? secondly is anyone here running a spintech dual muffler setup? i ran one on my previous dodge that was a true dual with x pipe and perf cats and it sounded nasty. (and passed smog ) haven't seen any for the sss chevy but was wondering if anyone was running this?

thomp62301 Posted September 26, 2006 Report Share Posted September 26, 2006 i ran spintech on 5.0 mustangs in the past and they sounded pretty sweet. i don't have any experience on the small block chevy's. as for the headers, i would check with dynatech i didn't think they were smog legal in ca.

thomp62301 Posted September 26, 2006 Report Share Posted September 26, 2006 as far as i know they bolt right up with no problem (o2 sensors etc...) Quote Link to comment Share on other sites More sharing options...
misterp Posted September 26, 2006 Report Share Posted September 26, 2006 The dynatechs work/fit/smog well, I think the company just did not go to the expense to get the CARB approval. Mr. P. Quote Link to comment Share on other sites More sharing options...
CaliChevyV8 Posted September 26, 2006 Report Share Posted September 26, 2006 But its $1000 per cat fine for relocating them. I wonder if the dynatechs count as "relocating" your cats... Quote Link to comment Share on other sites More sharing options...
rivierakid55 Posted September 26, 2006 Author Report Share Posted September 26, 2006 so here's the deal. i talked to tybrne today and they in turn talked to dynatech and said that "theoretically" the long tube headers should bolt up to an 06 but they have not test fit one yet. so is there anyone out there who knows if the 03-05 have the same exhaust configuration as the 06 as far as cats/02 bungs and such? i'd definately like to get in on these headers but am not feeling real confident about buying these right now. the good thing about california is still that we have 6 years of no smog for new vehicles so who cares if the cats are moved!

KissMySilvSS Posted September 26, 2006 Report Share Posted September 26, 2006 I believe that Dynatech Supermaxx Long Tube headers come with their own "higher flowing" cats, at least thats what it says on Tbyrne's site. Quote Link to comment Share on other sites More sharing options...
