Exhaust Size For Rb30

[sillo88]

hey guys, just wondering on your oppinions on what size i should go for with my exhaust. I own a r31 n/a skyline (rb30) and have been reading that a 2 1/2" system does it wonders, which it might on the track with your foot planted on the noise pedal! but its only a 3 litre and its my daily and i dont want to kill my toque, but maybe 2 1/2 isnt much at all and i wouldnt be endangering my performance and it could do it good! I plan on having extractors with a 2/12in outlet and then a hi flow cat straight out to the cannon.

soo what are your thoughts? 2 1/2in good or bad? be very happy on your thoughts

2 1/2in is fine.

Hey mate, I had the exact set-up on my ol VL, it worked very well and gave noticible power gains. The only thing I would recommend is a muffler, I really liked the sound for a couple of weeks after installing it but after a while I got tired of the drone and installed a 'hi-flow' muffler between the cat cannon/endpipe.

I dont know how people put up with it?!~?!?!

the muffler under the bum of the Supra is HUGE! plus a centre muffler as well, and it is loud while breathing through the 2 tiny standard turbos and standard dump and mid pipe

+1 for the tail end muffler on a supra being the size of a small europian country, there masive! lol

2.25 for auto.

2.5 for manual

One middle muffler (big oval one) , one cat , no rear muffler but rather a straight pipe and itll sound great. No rasp, not to loud etc.. Thats what I had on my old R31

[drift nut]

my manual had a 2.5 from the extractors to the muffler, no centre muffler

[20's_plenty]

ive got extractors with a new standard exhaust it goes really well and its dead quiet

[bozodos]

keep rear muffler delete centre one if more noise is wanted, otherwise it'll be drone city

[drift nut]

mine was fine the cat acted as a partial resonator, it was pretty quiet till you put your foot down

[Brendonams]

[Captain Natro]

[Brendonams]
