What Size Is Your Cat-back Exhaust?

[gotRICE?]

I cant vote.. Mines a 3.75inch

Mines a daily driven street car too. HKS Hi Power Silent...

mines a 3.5in fujitsubo, got a new mani + turbo going in at the mo, so i'm not sure what it sounds like yet

[ClutchBurndout-:(]

sorry guys, let me clarify, i want the loud exhaust with no drone, i understand this is hard to accomplish without spending big bucks

Trust PE2 is pretty rowdy when you smash the go pedal. But normal driving its really nice.

Lithium has one on his R33 with GT3076r. Its beautiful to drive/ride in normally, and then gives you the heebies when it opens up. Just roars.

We are currently working on some comparison clips. Will post up if we get some dry weather.

Pretty sure my A'pexi N1 is 3.75" after the muffler, doesn't drone imo and is also reasonably quiet until you hit the go pedal hard

get a better muffler or second muffler/resonator.

you cant have both.

i got 3" all the way to 5" tip.. jun exhaust loud i like it.

3 1/2in front/dump to 3in xforce cat, then 3 1/2 down to an apexi cannon. is a bit droney below 2500rpm, but above that is just music.

=/ i had a Trust PE2 before and thought it was way TOO loud...droned too much for my liking too.

Replaced with 3.5 x-force catback mid muffler and rear cannon.. better but still loud and droney.

Cut off rear muffler and replaced with a 3.5" varex - MUCH better. The varex mufflers are very large (as they need to have enough room to make 3 chambers for the gas to flow through in silent mode) so even at full open mode it's not too loud/droney and it sounds good too. Had to get the mid muffler repositioned too - thing was too low like previous posters mentioned and was scraping when attacking corners that were bumpy.

Now I don't have an R33, but I just fitted a 3.5 inch CES custom exhaust to my s15.

I thoroughly recommend it as it is not loud nor drony. I previously had their 3 inch system on my s15 which they claimed had legal db's and I can honestly say there 3.5 inch system is NO louder even with a 100 cpi cat. It has a large oval mid muffler and large oval twin tip muffler (with twin 2.5 inch dual skin perforated outlets) which are custom made at CES.

It cost me $1600 plus freight. Now that might be a little more than your willing to spend but...but what extra price do you put on a drone free and reasonably quiet exhaust?

I live in Perth and the exhaust was custom made at CES in QLD and yet despite this it's a beautifull fit even though the car was not there...tucks up nice and close to the body.

Also has twin tips as I wasn't keen on the cannon style to which Trevor at CES advised it would be slightly louder with the cannon.

Can snap some pics if you want to get an idea of the quality and fit.

You can't.

If you want a loud exhaust, it's going to drone @ low RPM. That is how sound works.

You can't have it silent and then suddenly loud legally.

You'd need to buy a valve of some sort that only opens above 2500rpm or something.

End of the day its always subjective anyway.

What some people say is "fine", is ridiculously loud to someone else.
