ive got the super turbo catback kit for my 84' Z28, but i want something a little more free flowing for my GTA project car and was wondering if dynomax made an Ultra Flow catback system. if not can you piece different parts from the super turbo kit (like intermediate pipe and tailpipes) with a ultra flow muffler? i think the ultamite catback would be a 3" inter pipe with an ultra flow stainless muffler. is such a thing possible and is anyone using something like this? thanks in advance

 

Yup they do, if u want the part # ill get it from work tomoro, but i hope u like big price tags... For the price of this system u could get a borla and another superturbo setup... IMO its not worth it I would just piece something together. But if ur a flashy spender go for it. Ill have that part # tomoro for you

 

Yeah, I ordered the ultra-flow catback and was told by the Summit rep that it was a 3" catback. What a crock, it was only 2-1/2" and was only 3" where it meets the cat. I sent it back immediately and got borla instead. After coming to my senses I decided borla was too much and sent it back also. Now I'm gonna just get the 4" Mufflex system instead. Definitely do yourself a favor and make sure you get a true 3" system like flowmaster.

 

Dynomax does not offer a true 3" kit. It has to be pieced together. I bought the 2 part I-pipe and crossflow muffler for about $250, and reused my old tail pipes from my superturbo kit.

 

i checked part #s from dynomax's website and this is what i got:

intermidiate pipe - 46669
ultraflow muffler- 17266
RH tailpipe - 43243
LH tailpipe - 43244

are these parts for a 3" system, or are they 2.5"?

 

Nope. The 3" i-pipe is 2 parts: 44063 Front I pipe & 43248 OA I pipe. The 3" in/ dual opp 2.5 out ultraflo muffler is p/n 17227.
