Wanting some advice!

 

Looking at buying a Maniflow exhaust when payday rolls around.

 

Looking at 2" twin boxes vs 2" single side exit.

 

i've looked on youtube to find that the cheaper single box has a nice raspy sound BUT at a constant speed is this going to be annoying and too loud?

 

Oh and any photos of the 2inch exhausts would  be cool!

Twin box every time for me. Single box is annoying loud

I've had a 1.75'' twin box side exit, with mini sport pro flo manifold, and it was really quiet. I've got a single box side exit 1.75'', with maniflow cooper freeflow manifold going on next. Personal preference really. I bought my car with a 2'' single box system which was quite loud.

Loud and really annoying. Stick with a twin box and drop the diameter abit

[robminibcy]

can't comment on 2" as mines 1.75 but I noticed very little difference between single and twin box (with an otherwise standard 998) there is slightly more noise on the overrun with the single box but other than that i didn't notice much. My mini is a 79 so doesn't have any real sound deadening like some later ones as well

What engine is it?  Unless it is 120bhp+ then a 2" system will be too big and you'll be throwing away power.

 

The ideal diameter are small bore engine: 1-3/4"; big bore engine: 1-7/8"

The fact that this question was posted in the styling section suggests your not concerned about the best system from a performance perspective ???? Exhausts are not actually there to look good !!!

nope, that just proves my point

[MBayliss]

I thought an exhaust was solely for making that bwarrrppp noise? I'm not too fussed on power gains as its a 998cc and have a daily with a nice bit of power. The mini is just something for the weekend. Thanks to those that have commented on noise -  will be going for the twin box i think and will look at a smaller diameter :)

I've got the twin box system and it's plenty throaty enough. It's got a nice rimmed edge too

I have a Peco single box and it's loud as hell. 1. 75" system on to a maniflow lcb. I try not to rev it too hard before 9am though incase I wake the neighbours hehe

[minifreek1]

I have a Maniflow LCB and centre pipe, mated to a centre exit Play Mini backbox and it aint loud at all.... just a nice throat to it on acceleration and a little bit of pop on overrun, but it aint loud....

I do love a rimmed edge.
