ashley exhaust

[novanova636]

im lookin at gettin a fully ashley exhaust system but i have a 1.2 spi mk2. what would be the best one to get? cheers dave

Ashley only make 1 type of exhaust system/manifold for a Nova.

[novanova636]

o right. they have the GTE,GSI and the SR listed separately and thought they were different

[Mike]

Does your standard manifold have a lamba sensor in it?

They only make on "type" so to speak, with teeny tiny alterations for injection/carb

[Sturge]

The 1.6 exhaust is slightly bigger bore than the 1.3. Get the sr one for the 1.2

[novanova636]

yeah its got the senser on the manifold. can i not get the 1.6 for even better flow?

[Sturge]

There's such a thing as too much flow. You'll lose back pressure and with it will go torque, dragging power with it.

Ashley are motorsport systems, designed for optimum flow on high output engines. The sr one is prob too big for a 1.2

[novanova636]

what exhaust would you sugest then?

[Sturge]

if you want a full system you'll be in the same boat with all of them tbh. Wont make much difference, but i'd imagine you'd notice it. Personally I'd just get a backbox, will still free things up a bit

[novanova636]

already got a back box. lookin into goin all out tunein the 1.2

[Sturge]

get the sr one then :)

[novanova636]

sweet. thanks for your help

[Mike]

^ i wouldnt waste your time nor hold your hopes up TBH as its never going to set the land speed record a wee 1200cc.

[novanova636]

no i know it wont be mega quick but i wont to see what i can do with it. iv owned a stupidly quick bmw so wanted to try a lil light nova

[Sturge]

stick a 1.6 in it, engine weighs the same

[novanova636]

was thinkin that. im lookin at a 1.4 on the bay atm

ALL novas have the same bore exhaust system.

I had a 2" bore ashley gte system on a 1.2i, no problems. Had to use a GTE manifold/downpipe too
