Need recomendation for exhaust size

[poonman]

Ok i got my header on and my muffler, live in florida so i cut out my cat. Question is, I'm running a 4-1 down with no cat to a 3a exhaust. it is just becoming way to loud for me to drive, becoming very annoying so i know i should make my pipes bigger. im only running an intake and a few transistor mods, what would someone recomend switching my exhaust pipe size too? 3" 3.5" 4"??

If its too loud its probably too big.

I don't know what the diameter of the 3a exhaust is but if its 3" try 2.5" or maybe even 2.25"

I would like to see a 420a with a 4" exhaust tho.

my exhaust inlet is 3.5 and i think my pipe now is 2 1/8, i have no problem at all going to a 4 as long as i don't loose back pressure.

i have the DTM3 i was even thinking about blocking off one of the tips, but i don't know what out comes it will result

I dont think any N/A should go 3inch but I could be wrong. Far as I would go on a non turbo set up would be 2.5 max. After that and it will just sound ugly.

it sounds nice now it just gets loud around 3 grand and gets very anoying when i drive by a cop, i wouldnt mind it being loud if the pitch was a lil lower

since yours is an n/a i would say no bigger than 2.5 max...an exhaust too big will actually hurt performance

I think you're talking about the muffler outlet size.

You shouldn't be thinking about getting 4" exhaust piping...unless of course you did a turbo diesel swap

Resonators.

They tone it down a bit and I believe they make the sound deeper.

 

[zimfro]

+1 for a resonator. They really help tone down the pitch of your exhaust, without too much restriction. The hard part is picking one because you won't really know how it will affect the sound.

An exhaust resonator is a restriction, regardless of where it is placed in the exhaust system.
