Do you need a big bore pipe with a 330 kit ??

[lee37vernon]

will i be ok running a sparks mx pipe and silencer or will i get loads better performance from a big bore pipe , (330 pro x) .. ?

[matt250r21]

I have read that any bore over 310 needs the big bore pipe so that it flows the exhaust right.

[Eddiesanders250]

No it doesnt need it.... take beerock for example, he uses a sparks TT pipe on his 330. I cant tell you how much performance you will gain but it does not need one..

[beerock]

yea im runnin the TT like he said, I never put my mx pipe on it, but I can bet it will still do a decent job and the mx pipe will give it GOBS of low-mid end. My 330 pulls ok in the low to mid but once you get past 1/2 throttle it pulls real hard.

the big bore pipes giv emore power ALL around so if you run the TT big bore it will be just like my pipe but with the entire power band amplified to even more power and the MX big bore is probably gut wrenchin

CPI makes two bigbore pipes, High rev and a midrange pipe. I switched from the TRX-5 center to the high rev and wouldn't even consider going back to the ESR. The only negatvie I've heard about running smaller diameter pipes on these big motors was heat issues.

:D you would be amazed what a 700 cpi pipe would do on a stock ported cyl. I have the 800 on my big bore 350 pv I will never buy a different brand of pipe. :D

Is this a question? When I talked to them he told me it would work fine for 330's on up to 380's. PV or non PV motors

[arego]

no i read your last post wrong thought It was all special orders and for 350 or larger....

I will just give em a call..

thanks for the number

Would I benefit from taking my 270cc mid range duner from the trx regular to the centermount, or would it not even be worth it? ESR said I would get more top and less bottom, but I don't know if that monkey was just trying to sell me a pipe.
