Exhaust for E36

[topclub]

What is the best exhaust diameter for my E36 325i ? 57mm? My car is a M50 I believe the branch is good and should leave it stock just replace the down pipe and right through to the back, what u guys suggest

 

[DROP IT - ZN]

A dual 50mm 2 box system works well

I`m with drop on this. Also planning to change mine to dual 50 mm:thumbs:

if you doing a full system then you should do branches as well... if it was just a decat then you can keep the stock items...

I can offer you:

Viper branch R 1685
Dyno tested Full Viper exhaust system including branch R 7640 (JHB and DBN only)

Sorry double post

you looking at a 10-20% gain on a full Viper system but every engine is different so there is some variation in results...

let me see if i can get a dyno sheet problem is they filed under car reg so finding the right car takes time

Moranor what size pipes u guys normally put on the E36 325i ?

 

[moranor@axis]

Abel wont give out his recipe but duel 50-54mm works well for that size engine...

the bends and welds are also critical its not just about pipe size...

plenty shops out there are willing to slap a crush bent system together cheap with over penetrated welds that can knock or rattle so be careful who you choose...

if you just after noise a Decat (not sure if your car has cats) and a free flow back box are your safest cheapest bet

Moranor how much without the branch? mild and stainless price?

 

[moranor@axis]

no point in doing mild steel its the labour that costs not the material...
