Straight through exhaust, no boxes..

How loud will this be?

Anyone done this/seen a video on youtube?

Thanks

Your a braver man than me. I have tried a straight through system before and it sounds the nuts... however your get pulled by the rollers (police) and you will be banned on track days...
However when the 5 cylinder starts reving it sounds awesome!

it will sound rather like an S1 i guess....

Guessing from sig, this on the TDi?
Diesel exhausts are a lot quiter unsilenced than a petrol.

Or you're doing it to a 4 litre BMW or 2.0 litre fiesta?

[Jas11n]

Duh, just seen project thread for that TDi, AAN going it.
Same as above, ears bleeding, but nice

I started my tdi up with just a downpipe when i was de-catting it and it honestly wasn't that loud at all.
Very tractor esc on idle but wasn't too bad once on boost.
I now run no cat and no box's apart from the stock backbox and its only slightly louder than standard but picks up a lot better

interesting to know about your system juggs.

And with regards to straight thru exhaust, stupidly loud will be the answer, I know another forum members running 400+ with a small side exit on his saloon and it sounds the nuts but you hear it miles away (which ain't a bad thing )

Yep this is on the TDi, I've removed one box from the 540 and its not enough but that's another story!

I guess that's what I will need to try, remove the system and just run the downpipe and see what its like!

i had a straight through 3" pipe and no cat at one point. if you are standing next to the car you have to shout to speak to anyone next to you like your in a nightclub!
Never got pulled by the plod but I only really slugged it round town with it in 6th gear permanently keeping the noise down. Only on the motorway I used to open the taps.

Throttle response is fantastic and the noise when you blip the throttle and get a cackle from the overrun is nothing short of amazing.

I have a straight throug exhaust, its a 2.75 and people exaggerate!

It's very very loud but you don't have to shout when standing next to it. It's boomy below 4000rpm and starts to sound amazing starting from 3500rpm.

But I do have earplugs in my car...

im no liar and im not exagerating.

it was that loud.

Maybe 3" has more of a ring to it, but im telling you now I had to shout to people if they were at the window and I had the engine running otherwise it was lots of "aye...what....eh...say that again."

...or I could've shut the engine off
