What Exhaust Set Up Would You Recommend?

[KyuubiGTR]

Hey all just wanted to get some info about exhausts whats a good set up?...ive got an r32 GTR with 280kw ive currently got a stock exhaust I assume for the sound and what not..im after somthing pretty loud but not straight pipe loud and good flow... What size pipe would be best eg dumps??,front?? So forth blah blah

Any info would be greatly appreciated

[scotty nm35]

Bigger is better for power but obviously you need to quieten it down for the street, and it would depend how low you are as to what size pipe would fit under the car.

There are plenty of 3 or 3.5 inch cat backs available in the for sale section, or you can get me or someone else to make you a full system if you want custom. PM me if you want me to organise a quote or just to drop around for a chat seeing as you're local.

[KyuubiGTR]

yeah I wouldn't mind a 3.5 but should i change dump and front sizes as well?

I've got 34 gtr dumps, and planning on a 3.5 inch custom. Go big, but get proper mufflers, stuffed with rockwool not fibreglass like the jap ones

[Hadouken]

Haha, I think so too. The MINES exhaust I have is quiet so I can't contribute.

im confused are you asking me if that set up is acceptable or is your input to the thread good haha...if your asking if the exhaust is good I have no idea about exhausts but it should be sweet for an rb20

[thekidd]

then a straight jasma muffler. that any good?

ahh I thought JASMA was a brand thanks for the info=)

[freyb]

jasma cool info. i thought its a brand as well haha. i saw it had trust written on it.

with regards to the cat. i dont care if its legal or not. im looking for an optimal exhaust design flow. not too loud and not restrictive as well. how about a 3" straight deisgn no cats no mid mufflers, just a straight bellmouth muffler on the end? would that work? im only aiming around 280-300hp

[KyuubiGTR]

anything straight will be pretty damn loud..but again i don't know much about exhaust i was actually hoping to get some info on it as well haha but yer you couldn't get much better flow then straight your neighbours will hate you as well

[freyb]

does the engine need back pressure btw? specifically to a rb turbo engine?

[BOOZTJUNKEY]

Ideally no u don't want back pressure on a turbo system it can lead to higher exhaust gas temps etc but u don't want to big of an exhaust generally rule thumb work out what power u want and build exhaust to suit of u want 250hpatw build a 2.5inch system . If u want 300hpatw get a 3 " system

Hope that helps bud

[AngryRB]

your already up near 280kw, id go 3.5inch dump and then 3.5inch system and add extra mufflers and resonators to quieten it down to what you want.

i wouldnt go any less than that.
