Brand Name exhausts + 4 door

[Spook's_Skyline]

will brand name cat back exhausts fit my 4 door? (N1, super dragger etc)

i know some exhausts are made for 4 doors, but will i just be able to source a second hand example of the above and have it fit ok?

[4door_Sleeper]

the floor pan is the same for a 4 or 2 door so it should fit

you will find that 95% of parts for a 2 door will fit the 4 door (the other 5% is fairly obvious - with the exception of the rear strut brace)

I reckon that the most you would have to do is replace the tip with a slightly longer one. I don't know about you guys but mine is 5cm longer in the boot. That's not much when you think about it.

Mine is being fitted in about a week so I'll let you know what I find out then.

Some can, some don't. So better checkout websites like www.takakaira.co.jp or www.perfectrun.com.au as their online list is pretty detailed mentioning whether a certain exhaust will fit 2D only, Manual trans only or models with A-LSD etc. etc.

G'luck.

Jap coupe exhaust fits my sedan fine... Only quirk is the tip sits slightly under the bar... at most 1.5inches...

There's a clause in regards to ADR or vehicle modification guide that states exhaust gases must exit within a certain distance from the last edge of a car's floorpan. This could mean all floorpan including the edge of your boot floorpan.

In your case, it may have caused the car to be non roadworthy, and when certain authorities start to realise this, there's a whole lot of new possibilities to defect cars based on this ground rule.

See Vehicle Standards Information 8 Section 12 regarding Exhaust.

The exhaust outlet must extend at least 40 mm beyond the furthermost outboard or rearmost joint of the floor pan which is not continuously welded or permanently sealed which could permit direct access of exhaust gases to the passenger compartment

Any exhaust shop could modify the Jap exhaust to fit for very cheap.

The tip is still within the surrounds of the rear bar... I've got bigger issues to worry about...
