hey whats up guys,
pretty straight forward question:

with new 4.2.1 headers and exhaust system, would i be able to keep my stock sir muffler?

or do i need sumthin a little more power driven?

....SUCH AS a type R or GSR muffler?

thanks---

i would sugest a aftermarket performance mufler

shlammed

no point in getting everything else done if its just gonna be bogged down at the end

vtektchi_

see, the point is that i dont want anything that sounds like thunder, lol...
if you have any suggestions on some relatively quiet aftermarkter mufflers, but stll hold the performance then please tell me...
thanks.

take a look at speedy auto that's were i got my mufller, price is not bad ,it's a dual tip stainless steel muffler, as long u keep the resoner and the cat u should be ok, and if u keep the same pipe it's a bit better to, but i sure went with the 2 1/4" stainless still

shlammed

custom 2.25" stainless cat-back with hi-flow cat on my piece of **** DX and i could feel the difference

reddevilcivic

ya but how loud is it? he wont's to have performance but still quiet

Go with a dynomax superturbo...really quiet exhaust

imported_Cablerat

Isn't a type-r exhaust 2 1/4?

bogged down at the end... how much wider u need? planning a turbo?

vtektchi_

nah i aint planning a turbo...
pure motor,
im prolly going with the 2.25 inch... any objections?

but i was wondering if the stock sir muffler would be fine to complete the exhaust system...

doesnt seem so, i'll go checkout that dynomax superturbo for now... but if i put on a GSR or type R muffler, would that "bog it down"?

imported_eth0r

if ur going with a turbo ur going to want a free flowing exhaust..i myself am using a type r exhaust.. i have no complaints

cee_mon

He isnt going turbo he said...
Also 2.25 sounds fine....i would try and find a Type R exhaust, cause it will mate up to the piping no problem and is the best flowing stock exhaust for hondas.

vtektchi_

awesome, so far its the type r muffler....
thanks for responses

Just got a dynomax superturbo installed on my hatch on the advice of some pple here. ABSOLUTELY FREAKING LOVE IT!
Replaced a Vibrant straight thru that just got too loud for my tastes. The superturbo has a nice deep sound for city driving... not loud.. and as quiet as stock when you hit the highway.
Sweet azz bump for Dynomax... 200 installed at Hot Rod Scott's.

vtektchi_

anyone got any sound clips of this dynomax superturbo?

vtektchi_

FOund one, yeah it duzz sound very nice,
i'ma look into it

dingus8

my list:
type r muffler
apexi world sport
mugan twin loop....ractive also makes a replica that isnt' 1000 bux..
comptech
turbo muffler..flow master or dynamax

I'd go with a type r muffler for the clean stock look

spracingsports

like dingus said, the apex'i world sport is a sweet as exhaust, and very quiet too?

Last weekend, I got sick of my loud exhaust. It sounded really nice in the city, but when I drive on the highway, it drones and makes me get headaches... (I've been driving far for work lately).

I threw it out on Saturday (only 4 months old, still mint), and immediately went looking around for a Dynomax super turbo muffler. I couldn't find one, and also didn't want to risk it still being "too loud" for my tastes... so I broke down and got.... guess what muffler... a muffler from NAPA that was huge but had the right offsets.... a replacement muffler for a Mercury Capri or cougar... lol It actually fits! (But the tailpipe ended pointing straight up into the air! ya ya, I quickly ghetto fixed that with a grinder.) It was the best fitting muffler, which I hand picked from their back room of hanging mufflers.

The inlet/outlet was 2.25 so I was happy, plus it was relatively cheap ($75). This matches my bent 2.25 piping everywhere else.
(Which was a huge improvement over the aftermarket "stock" 1.5 inch piping I had previosly, with a B18B! Choke choke!)

I bought some clamps, a coupling/adapter, and then threw it on in haste and mig welded some hangers. Its positioned too far back and looks awful... I'll fix its appearance when I get more time...

The weird thing is, that my performance has definetly improved!!! I would have guessed that the loud - no-name-3-chamber performace muffler I had on prior to this would be noisier but faster, but this quiet setup I now have is amazing.

My car is stealthy quiet, and it still seems obscenely fast. I swear I have more torque at low rpm's too. I was semi-unintentionally peeling out in 3rd gear, and that never happened so easily before!

I guess just proved to myself that crappy-no-name three chamber performance mufflers are trash, and even a stock big-*** american car muffler outperforms that!

I think that I might simply have gotten lucky with a chance combination of pipe sizing, resonance frequency, placement of the components (resonator, cat, muffler) etc., which has now given me a better "tuned" exhaust.
