I should post a sound clip from the 4age with a magnaflow exhaust....Its so freakin loud driving it. Its got the good ol deep sporty tone and at high revs it sounds like a bomb exploding.
I have a ricer question - 6G Celicas Forums
ooooook here is what i learned and read on the subject... Long long time ago i was experimenting with all the tipes of mufflers / resonators.. I did 3 my own mufflers (straight trough design) and 3 resonators, all of them where different.
Basicly - the sound depends from whole system, if you have good flowing system and inside the pipes where are no sharp edges, no welding marks left - it will sound clean (no puf puf and no dra dra when you rev it and realise the gas pedal)
Second thing - Resonator / Muffler ( when they are the straight through design), the size / diameter of them will make your sound either risey or a nice deep tone. The Diameter will deside what tone your sound will be the bigger diameter and short lenght will give you higher pitch sound, cuz the big bang will be slowed down but all the small ding ding sounds will be left untouched. The smaller diameter and longer ones will give you a loud but clean deep tone cuz all the small pitching will be damped and deep but loud sound will go out.. The combination of these two parameters will give you desired sound.. When going custom it all depends on the design of these 2...
Why do you think Greddy SP sounds so damn good? take a look at the rear muffler - the size of it is almost the same as Stock one, and the resonator is almost the same too.
In this case - size matter - but matter only if you want to quiet down the sound, but queting the sound - means slowing donw the exhaust gases... so... it is for you to chose.
Best exhaust - straight pipe of 1 meter long and some sort of funnel type tip on the end... Sound will be amazing

It also makes a difference how many valves per cylinder an engine has, 4 valve engines alyways have a higher pitched note compared to 2 valve. My 18rg and 2tg celicas sound heaps deeper and gruntier compared to the 5s
how much of a factor does boost play?

Huge. You can run open down pipe and you will be able to drive and sound wount be so damn huge. Turbo cuts away about 50 - 70% of sound, cuz it slows down the gases.

My friend has a RB26 in his s13. Single turbo, 4inch exhaust from front to back(straight), experimental engine and trans mounts, AEM standalone coustom tuned. It took him 8 months from start 2 finish including tuning time. He runs 12.8s, but hez got mad boost leak. Hez sellin his car soon for $21K soon, hopefully.

very soon i will have one...and i would love to rb26, but u dont understand the work and money thats involved...first u need a custom drive shaft, rwd tranny of an rb25....the most elaborate downpipe if you want to keep both turbos..pluse the engine it self is close to 5k, and thats even shipped. not to mention you gonna need to fab up engine and tranny mounts...all in all, if u got the cash go for it, but the rb20 is 10x cheaper and 10x easier to install..u jus bolt up the k member, i can use my drive shaft..hell i could use my own tranny if i wanted, but it's not as strong..PLUSE, most parts like clutchs and things are that nature are the same as an n/a 300zx, so parts wont be that hard to find
