Celica Forums General Discussion Engine and Performance custom exhaust

alright, sound aside (dont need anyone whos gonna be complainin about how loud its gonna be or the tickets ima get because i dont really care), if i went with a custom exhaust similar to the kazuma,(no cat, no muffler, just str8 pipe with a resonator) would i be getting the biggest hp gains? and that should probably be cheaper then buying the kazuma itself correct? how much should i expect to pay? just askin to see if i should even bother goin to the shop for an estimat.

exhaust alone will not make a huge difference. I would recomend going with a reputable aftermarket exhaust. I have a greddy axle back, it's nice because it has some of the best gains, and is very quiet at idle and low rpm, but sounds great at high rpm. I've heard TPR's exhaust is great, but you may have to wait. If you buy a used system, it should be about the same cost as a custom one.

depends on what size piping you go with, i have the kazuma with 2.5" piping and the gains to me are great. more power at higher rpms. if you buy the kazuma new its $350 bucks.

yea im gonna go pretty much wit kazuma specs eg 2.5" piping, i was just wondering if anyone knew how much i could expect to pay for it custom made, and also i still dont know the freakin gains on the kazuma, i want an actual number, or atleast an approx number

a good custom set up will cost over $500, you'd probably get similar gains (but smaller) from a TRD exhaust that you could get for like $250 used. i have a custom Veilside titanium canister with madrel bemnt piping that i spent about $550 total for. very nice top end but its loud and has a not so good low end. I also have a TRD exhaust that has excellent low end but top end sucks badly.

ive heard that custom exhuast is usually cheaper, not sure how true that is. any one else with an exhaust similar to my idea or if you have a kazuma plz post.

well it depends how nice you want it. i dunno how you can run with out a cat (sensor will give a CEL) but if you get really nice piping thats madrel bent and have a nice welds you're looking at a lot more than i paid cause your talking about making a whole new mid-pipe. too big a piping and i think you'll lose a lot of your low end power.

doesnt kazuma eliminate the cat? and no cel pops up?

no it welds on after the cat.

i had a custom 3in mandrel made for me for 260$ from my DP back. i do have a little hook up but not much

how are the gains on that and do you have a muffler on it?

ya i have a muffler
its a lot more responsive than stock 2.25
sounds really nice, never had a chance to dyno since i
blew the motor

just got back from the shop and im excited my friend works there and hes tellin me custom intake and custom straight 2.5" exhaust with a resonator and muffler 250 installed. thats very cheap.

If it's a crush bent exhaust, I wouldn't bother with it. Mandrel bends are the way to go as far as flow rates of piping.

And to those who want to run straight pipes without a cat, do us and the enviornment a favor and buy a carsound hi-flo cat. It will flow much better than the stock cat, keep the exhaust quiter than a straight pipping, and still keep smog down.

Also, use magnaflow straight through resonators on your custom exhaust setup to get rid of any "ricer buzz" without sacrificing flow.

my 3in with no cat but the DP cat, does not have the ricer buzz, but actually has a sweet WOT sound and is wicked with the turbo

well i just talked to the shop and this is wat im gonna do, theyre gonna custom design the intake for me for 70 bucks installed and everythin. right now i got no work so i dont got the 250 for everythin. as soon as i get a job though ima go and get that exhaust.

Make sure you get a resonator with that exhaust!
