Spoon N1 - Raspy Sound or other?

I currently have the standard EP3 backback and an unsilenced sportex B-Pipe. This gives a very nice raspy sound, especially at lower to mid revs. The problem with this setup is the B-Pipe scrapes on certain speed bumps. The other thing is when the car gets to higher revs, the engine note changes from raspy to droney. Idealy, I would like to keep the raspy sound.

One option of was thinking about was to go back to the standard EP3 B-Pipe to cure the speed bump issue and get a Spoon N1 back box. However, I really don't want to lose that raspy sound. Would I keep this raspy tone with this setup or would I get a totally different sound again going back to the OEM B-Pipe and a Spoon N1 backbox?

I have viewed some Youtube vids but in all honesty its quite difficult to tell listening on a computer. Would be interested to hear from people who have this setup. Cheers.

I have had the Sportex b pipe and Spoon N1 setup, Most of the rasp comes from the b pipe. It was fairly deep sounding on start up, there was a lot more rasp higher up the rev range with this combo. I hadnt tried the setup with the standard b pipe as mine was past it. (I dont notice any drone currently with same set up as you, i find a pretty quiet set up) I now have the sportex b pipe and OEM back box (as ive had to sell the N1 :( due to paycut).
I think you would lose alot of the rasp you have now as the N1 will deepen the tone.

Have you looked at other unsilenced b pipes that dont hang as low? as i know the sportex hang very low. The sportex b pipes hang really low on all different car fittments. The mild steel on the sportex is heavy and unforgiving with scrapes.

Thanks for the reply. I had not considered any alternative B-Pipes as I thought they all hanged down low. If others don't and its just the Sportex one then this could be my answer. Do you have any recommendations for alternative B-Pipes?
 
Unless your car is lowered you shouldn't have any issues with a b-pipe and scrapes, they don't or shouldn't hang that low and should be similar to the standard one. The Spoon b-pipe (which is what I would look at) sits fine and has no issues with scraping on a standard car or indeed one lowered on springs (within reason)
 
+1 for Spoon Bpipe.

I would only go for the spoon stuff if you absolutely positively never plan on doing a trackday/ spa or ring trip.

My EP3 before it was lowered would scrape on certain speedbumps but we do have some aggresive speed bumps around here :(
 
The sportex b pipe does scrape even at stupidly low speeds on harsh speed bumps even when not lowered. It's a faily crap design. But for the price you can't complain.

I have the same setup, apart from mine is 2" custom unsilenced b-pipe... and I know what you mean, when you get close to 4000rpm the engine note changes and becomes droney... but it seems to calm down abit once you pass 45-4700rpm. Is this the same with yours?

Would changing to a silenced b-pipe affect performance? and would it get rid of the drone?

Yes, thats what mine does. I do believe going to silenced would affect performance. To what degree I don't know but I guess not a lot. I'm sure someone with more knowledge will be able to clarify.
