hey everyone!
i just bought my new Dynomax Super-Turbo Cat-Back exhaust system today! i got it pretty cheap too- got it from Pep-boys for only $106 b/c they weren't selling them anymore. anyone gimme some info on them?-like friends having it or u personally having it, any info would be great since im not gettin it installed for a few weeks b/c ive been out of work b/c i had surgery. how much would it cost to get it installed at a shop?

thanks alot guys+gals

wait elaborate on how u got it so cheap? whats the retail price on those things? any chance i could score teh same thing at my local pepboys?

I dont want to break your heart but measure the intermediate pipe. I had bought one of those systems too and it only had 2 1/2 in pipe, smaller than stock.

is 2.5in pipe really that bad? what would i have to do in order to change it and how much would it cost? would i have to mount it differently or anything? change any hangers? im new at this so thats why i ask you guys, the experts....also do u recommend getting a new cat or could i just gut the factory cat?

thanks alot guys

im assumin NY emissions is similar to NJ? total assumption. i would just keep the cat as is, unless it is totally used up then replace it with a new one (freer flowing if youd like ...catco, random technologies are two brands) keeping the cat doesnt kill power the way people make them out to and it could save you some hassle in the future. if hes right about the pipe diameter, you might wanna try and sell that cat back , i bet you could get what you payed seeing as you got it on discount.
while your 305 doesnt seem to be crankin out loads of power, you would still want a 3 inch pipe. good luck!
welcome to the boards and the wonderful world of thirdgens!!

considering that i only have a 305 and i dont plan on doin too many upgrades on this engine(exhaust, open element,etc.), a 2.5" pipe would be ok right? i mean i am saving most of my money for a new engine so then id upgrade all the pipes to 3". but for now this could suffice right?

thanks

I think that 2.5" pipe is fine for a mild 305. Which 305 do you have? If its an LG4 then 2.5" will be plenty. I have a dynomax on mine. It sounds better than stock but its very quiet. I ordered a Flowmaster 40 series from summit yesterday, so that should solve that problem

Yes. The cat inlet is only 2-1/4", so the restriction will still be there even though the Dynomax I-pipe is 2-1/2".

hey man i was wondering if u liked the sound of the dynomax but u just wanted a louder muffler or were u not happy with the dynomax? i know its quiet but i like it like that, not to loud and angry lol... what about when you got on it and WOT, how was it then?? thanks alot

It wasn't a bad sound at all, just quiet. You can hear it at WOT, but its not horribly loud. I was very happy with the sound, just not loud enough for my tastes.
