Some exhaust dilema... - Third Generation F-Body Message Boards

Hey, I am considering an exhaust options for my new engine
(basicly modded ZZ4 MPFI, putting a bit higher numbers then originaly ZZ4)

I am not yet shure what headers I will get, there are three options - SLP 1 3/4 shortys, Hedmann long tubes 1 5/8 and Daugs longs 1 3/4...

Then cutouts - the best idea (just for having really, really loud agresive tone) would be to have both, palced just after the headers but I dont know if they would fit there.. I mean without sacrificing to much clearance..

Then my main question - do I put a cat there?
I do not have to take any emission tests in my country, all I want is the best power I can get.

As for a muffler I was thinking about Powerstick or maybe GMMG chambered. Either a 20' in place of an I-pipe or two at the cars end like at the GMMG website.

What do you guys think?

Imo the powerstick would sound sick.

Hehe, that is what I hope for

How about the cat? Do I need it..? I will be using heated O2 sensor of course, but the Powerstick is probably less restrictive then normal muffler..

cool motor & car, how did you get it to Poland? Forget the cat if emissions are not a problem and power is the goal

I got it from Germany, hehe

It was a good deal, payed almost nothing.. but had a V6 then.. So only thing left to do is buy an engine and get more power

I also have a 1966 Pontiac Catlina Convertible directly from USA
