What can I do to the exhaust of a Z28 prolly a LT1to make it nice and LOUD and I mean LOUD.. Stand out in a crowd loud... like able tomake a few 2nd gen camaros sound like 4cyls but keep it emissions legal? Mufflers? Headers? Cam?

 

Put megaphones at the end of the tailpipe.

 

IMO loud does not always mean it sounds good. You need compression and a big cam too. The SLP Loudmouth is the loudest exhaust that I know of that is a ready to bolt on deal.

 

Yeah,for great loudsound. What would be the best combination from theheaders on back?

Now that im looking around at exhaust... What is the design of a Z28s catback? Is it this?

Is there a chance for going true dual... with two mufflers? Have a pipe fabbed to go from each header (no crossor mid pipe)to a single in single out muffler on eachside? Rather than the catback above?

 

Like this without the cross pipe:

 

$th gens don't really have room for true duals. It has been done but it either never fits right or looks hack. A 3 inch y-pipe and 3 inch cat back can support 500+ hp.

 

I know a guy here in sweden with a 95 Z with Procharger, he had a 3" exhaust up to around 600hp but he had to get a 4" exhaust when he got more power, has around 850hp now in the same engine.
So a singel 3" goes a long way!

 

hmm...Well, if you don't care how the back of your car looks, get some Long tube headers and stick 2 cats on the collectors, and run duals and dump them before the axel, it'll be loud, er, really really loud. Frankly, I'd go with a good set of emissions legal long tubes(they're hard to find...Kooks worked well for me!) with a catted Y from the same company, and then you could get the SLP Loudmouth system and drop the resonator and weld in a piece of pipe, then you'd have straight pipes back. IMO it'd be way too loud...after starting my car with open headers I'm glad that I have an exhaust system that at least cuts out some of the sound.

 

but Y pipes suck.. my friggin V6 had Y pipe... What prevents a 4th Gen from having dual exhaust? Doesnt the Y surpress power anyway?

 

Cut outs my friend
