I purchased a full exhaust system 1 week ago for an SV1000, replacement stainless steel exhaust system and new mufflers. I was really impressed with the quality of the product throughout and would thoroughly recommend them. The resultant sound is also very pleasant, slightly deeper than the original with a small amount of crackle when rolling off the throttle, but nothing anti social. Really nice. The only reason I haven’t given the product 5 stars is that the kit didn’t come with enough exhaust paste and I had to buy some more (it may be I used too much, but at £1.99 a tube it wasn’t much.) It was also a bit of a bugger to fit (be prepared for skinned knuckles & make sure you do some research on how to remove the rear header pipe from the block!). Overall extremely pleased & well worth the money.
